Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.
======================================================================

I have removed ~/.asoundrc , but the result is the same (100% CPU load with
5.1).
@Raymond: What am I supposed do with the information "center_lfe is device
3" ?!?
----------------------------------------------------------------------
bitmage2 - 07-14-06 20:59
----------------------------------------------------------------------
For your information: *After* removing ~/.asoudrc , the output looks like
this:
chris@bjork:~> speaker-test -Dplug:surround51 --channels 6
speaker-test 0.0.8
Playback device is plug:surround51
Stream parameters are 48000Hz, S16_LE, 6 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 16 to 16384
Period size range from 8 to 512
Periods = 4
Buffer time size 2525
To choose buffer_size = 16384
To choose period_size = 4096
was set period_size = 512
was set buffer_size = 16384
0 - Front Left
4 - Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE
Time per period = 17,710859
It says "3 - Rear Right", and it actually plays sound at "rear right".

For the bug reported in alsa-user mailing list,
pcm.stereo41 {
type route
slave.pcm surround41
slave.channels 5
ttable.0.0 1 # 0 + 2 left channel
ttable.0.2 1
ttable.1.1 1 # 1 + 3 right channel
ttable.1.3 1
ttable.0.4 1 # 4 - subwoofer
}
AFAIK, 5 channels (surround41) is most likely not supported for most ALSA
drivers. If surround41 and surround50 is not defined in CS46xx.conf, it
usually mean unsupported(or not yet supported). Please correct me if I am
wrong

This is the normal behaviour of ALSA application for sound card with
mutilple subdevices since snd_pcm_hw_params() fail.
If you run 10 instances of 'speaker-test -Dsurround51 -c 6 -t wav'
concurrently, run another instance of 'speaker-test -c 2 -t wav'.
All 31 pcm_channels of cs46xx should be used up by now.
What happen if you run an OSS application (e.g. mplayer -ao oss
stereo.wav') ?

Are there any reason which prevent you to upgrade to ALSA 1.0.12rc1 ?
In kernel 2.4, I can easily switch between different version of ALSA from
1.0.2 to 1.0.12rc1.
you have to ask the ALSA developer how to switch between stable and
development version of ALSA in kernel 2.6
The only way to find out the maximum number of instances of "surround41" ,
"surround51" and "surround71" is to open pcm, set_channels and other
parameter and call snd_pcm_hw_params() until snd_pcm_open() or
snd_pcm_hw_params() fail
You may try set_params_test4.c and post the result in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1724 if cs46xx
can use the new function snd_pcm_set_params().

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.
======================================================================
----------------------------------------------------------------------
Raymond - 08-01-06 02:40
----------------------------------------------------------------------
There should be a female voice speaking the channel name on the
corresponding speaker when you specify '-t wav' option of speaker-test
(you need to use speake-test in alsa-utils 1.0.12rc1)
----------------------------------------------------------------------
Raymond - 08-01-06 04:15
----------------------------------------------------------------------
Are there any reason which prevent you to upgrade to ALSA 1.0.12rc1 ?
In kernel 2.4, I can easily switch between different version of ALSA from
1.0.2 to 1.0.12rc1.
you have to ask the ALSA developer how to switch between stable and
development version of ALSA in kernel 2.6
The only way to find out the maximum number of instances of "surround41" ,
"surround51" and "surround71" is to open pcm, set_channels and other
parameter and call snd_pcm_hw_params() until snd_pcm_open() or
snd_pcm_hw_params() fail
You may try set_params_test4.c and post the result in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1724 if cs46xx
can use the new function snd_pcm_set_params().

Yes, 'speaker-test -c 6 -Dsurround51 -t wav' runs correctly for 20 rounds
(correctly = shown channel gets played every time).
BTW: I found one (probably unrelated) information about the rear channel
(on Hercules Game Theter XP7.1): The rear channels volume is regulated by
controls Surround.0 and PCM.1 - this is very strange, as PCM.1 is the ONLY
"index 1"-device I found that is doing something useful.
PS: This test was made with ALSA 1.0.9b.

May be the wrong noises is related to the problem of '-t wav' option as

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.

How many instances of surround40 or surround51 can you run ? It hard to
notice 'out of sync' when using speaker-test
You may try the upmix plugin in alsa-plugins-1.0.12rc1 for up-mixing 2
channels to 6 channels.
Wound you mind run set_params_test.c and post the result in
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1724 ?

I have tested and can run multiple instances of all three commands (means:
also the "-Drear" one works) without commenting out the "lock".
It also works if I comment out the "lock" in the "CS46xx.pcm.rear.0"
section of /usr/share/alsa/cards/CS46xx.conf .
After testing further I have good news and bad news:
The good news: "speaker-test -c 6 -Dsurround51 -t wav" does not go to 100%
CPU load when removing the "lock". :-)
So far - so good. But my original stated goal was: "use the rest of my 5.1
speaker set". And this goal includes playing back 2-channel MP3 files on
all 6 speakers.
So here's the bad news: I created a .asoundrc with a channel duplicator
"pcm.ch51dup" or "pcm.duplicate" (see below. I found those on the
internet). Using any of those two, the CPU goes again to 100% (Example:
"speaker-test -Dch51dup -c 2 -t wav").

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.

If you can run multiple instance of
speaker-test -Dfront -c 2 -t wav
speaker-test -Dcenter_lfe -c 2 -t wav
but not
speaker-test -Drear -c 2 -t wav
00-00: CS46xx : CS46xx : playback 31 : capture 1
00-01: CS46xx - Rear : CS46xx - Rear : playback 31
00-02: CS46xx - IEC958 : CS46xx - IEC958 : playback 1
00-03: CS46xx - Center LFE : CS46xx - Center LFE : playback 31
The problem will be the lock in rear device if you have more than one
applications using the rear device
Just comment the lock like EMU10K1.conf
http://hg-mirror.alsa-project.org/alsa-lib?cmd=changeset;node=ad1bdc38bce9;style=gitweb
----------------------------------------------------------------------
bitmage2 - 07-25-06 21:53
----------------------------------------------------------------------
I have tested and can run multiple instances of all three commands (means:
also the "-Drear" one works) without commenting out the "lock".
It also works if I comment out the "lock" in the "CS46xx.pcm.rear.0"
section of /usr/share/alsa/cards/CS46xx.conf .
After testing further I have good news and bad news:
The good news: "speaker-test -c 6 -Dsurround51 -t wav" does not go to 100%
CPU load when removing the "lock". :-)
So far - so good. But my original stated goal was: "use the rest of my 5.1
speaker set". And this goal includes playing back 2-channel MP3 files on
all 6 speakers.
So here's the bad news: I created a .asoundrc with a channel duplicator
"pcm.ch51dup" or "pcm.duplicate" (see below. I found those on the
internet). Using any of those two, the CPU goes again to 100% (Example:
"speaker-test -Dch51dup -c 2 -t wav").

I just validated, that the problem is still there in 1.0.12rc1 . I did
install that version on a clean linux installation.
I also did a "strace speaker-test ...". While everything works fine, it
looks like this:
...
poll([{fd=4, events=POLLOUT|POLLERR|POLLNVAL, revents=POLLOUT}], 1, -1) =
1
ioctl(4, 0x4122, 0xbfeb2ab8) = 0

ioctl(4, 0x4122, 0xbfeb2ab8) = 0
poll([{fd=4, events=POLLOUT|POLLERR|POLLNVAL, revents=POLLOUT}], 1, -1) =
1
ioctl(4, 0x4122, 0xbfeb2ab8) = 0
ioctl(4, 0x4122, 0xbfeb2ab8) = 0
...
When the problem shows up, the strace output is this (not calling poll()
anymore):
ioctl(4, 0x4122, 0xbfeb2ab8) = 0
ioctl(4, 0x4122, 0xbfeb2ab8) = 0
ioctl(4, 0x4122, 0xbfeb2ab8) = 0

It is possible that you have many sound servers(e.g. esd, arts, ... )
running without notice since cs46xx support hardware mixing ( multiple
subdevices )
00-00: CS46xx : CS46xx : playback 31 : capture 1
00-01: CS46xx - Rear : CS46xx - Rear : playback 31
00-02: CS46xx - IEC958 : CS46xx - IEC958 : playback 1
00-03: CS46xx - Center LFE : CS46xx - Center LFE : playback 31
The problem will be the lock in rear device if you have any sound
server(OSS emulation) which use more than 2 channels

It seem that the lock in CS46xx.pcm.rear may has side effect since the rear
device of CS46xx support hardware mixing ( multiple subdevice )
https://bugtrack.alsa-project.org/alsa-bug/view.php?id=1823
hooks.0 {
type ctl_elems
hook_args [
{
name "Duplicate Front"
lock true
preserve true
value 0
optional true
}
]
}
Are there any difference in calulating the period_size, period and
buffer_size surround40 , surround51 for cs46xx (multi plugin with front,
rear and center_lfe) and ice1724 ( single device support 2,4,6,8 channels
) ? https://bugtrack.alsa-project.org/alsa-bug/view.php?id=2244

But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional

The installed RPM package "alsa" is 1.0.9-23.2 (includes alsa-lib ,
alsa-utils , alsa-conf and libasound. This means alsa-lib and alsa-utils
should be the same version.
If it helps, I can install alsa 1.0.12rc1 now on a clean Linux
installtion. Should I do so?
About the test cases:
speaker-test -c 2 -t wav # Does not produce high load
speaker-test -c 4 -Dsurround40 -t wav # Produces high load
speaker-test -c 6 -Dsurround51 -t wav # Produces high load
While playing around I made an interesting observation: The two
probleamtic cases do not produce high load, if the machine is otherwise
*completely* idle (means: don't move the mouse). If I start some activity
(for example starting Firefox, use a file manager or execute something
like "cat /boot/vmlinuz"), speaker-test immediately goes to 100% CPU time.
In this case often a "Broken pipe" can be observed (see below).
"speaker-test -c 2 -t wav" always works, no matter how hard I stress the
machine.

It seem that the lock in CS46xx.pcm.rear may has side effect since the rear
device of CS46xx support hardware mixing ( multiple subdevice )

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.

Well, you could just install over your current drivers, then if it does not
work, reinstall the version that your distro supplies.
"PS: I am still somewhat astonished, that a driver/library/whatsoever
being younger than a year cannot be fixed. Actually, if installing drivers
wouldn't be so complicated and time-wating on Linux, I wouldn't care so
much. :-|"
Sorry, that's just how Linux works. There is very limited manpower to
support an insane amount of hardware and we don't have the resources to go
back and fix 50 old versions every time a bug is found. If you want
support for the latest and greatest hardware you need to run a recent
version. A year is a LONG time in the Linux world.

Info: I can confirm that the bug is there in ALSA 1.0.10rc3 , Linux kernel
2.6.15-23-386 (just downloaded Kubuntu 6.06 just for checking this).
My check against "1.0.12-rc1" will take plenty of time, because it means
to find a spare HD/filesystem, install a Linux distribution, get ALSA
compiling (it is more than a year since my last compile/install of ALSA).
If I find a current live CD, it might speed up the process.

By "too old to debug" I mean that even if the bug is found, a year old ALSA
version can't be fixed - the answer will be to just upgrade. 1.0.12-rc1
will work with 2.6.13.
We need to determine whether the bug is present in the latest version, so
you'll have to try 1.0.12-rc1.

2.6.15-23-386 (just downloaded Kubuntu 6.06 just for checking this).
My check against "1.0.12-rc1" will take plenty of time, because it means
to find a spare HD/filesystem, install a Linux distribution, get ALSA
compiling (it is more than a year since my last compile/install of ALSA).
If I find a current live CD, it might speed up the process.
Chris
PS: I am still somewhat astonished, that a driver/library/whatsoever being
younger than a year cannot be fixed. Actually, if installing drivers
wouldn't be so complicated and time-wating on Linux, I wouldn't care so
much. :-|

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.

Haven't tried. 1.0.12-rc1 is just too new too install. Even most current
Linux distributions like SuSE 10.1 ship something like 1.0.11-rc2.
Is ALSA 1.0.12-rc1 qualified to run with Linux 2.6.13 (my current kernel)?
Just don't want to mess up my ALSA application development environment if
this setup isn't supported and/or chances are slim that installing
1.0.12-rc1 will help.
Would it be easier to debug when I install 1.0.12-rc1? rlrevell's comment
indicates this, but I don't see currentlx how. Do I need to build a debug
version of ALSA?
----------------------------------------------------------------------
rlrevell - 07-14-06 22:57
----------------------------------------------------------------------
By "too old to debug" I mean that even if the bug is found, a year old ALSA
version can't be fixed - the answer will be to just upgrade. 1.0.12-rc1
will work with 2.6.13.
We need to determine whether the bug is present in the latest version, so
you'll have to try 1.0.12-rc1.

Summary: Playing surround sound produces 100% CPU load
Description:
I am using the CS46xx with a Hercules Gametheater XP 5.1 . It plays back
stereo without problems.
I wanted to use the rest of my 5.1 speaker set, so for a test I ran the
speaker-test program. Running it without parameters or with 2 or 4.0
channels works also fine. So far so good.
But when I run it with 5.0 channels or 5.1 channels the CPU load of
speaker-test goes to 100%. I'll show the output of top along with the
command lines below (for the 2.0 and 5.1 case) in the "Additional
Information" box.
