[Qemu-devel] Audio

[malc]

Hello,

At http://www.boblycat.org/~malc/code/patches/qemu/ you will find
latest(7th) audio patch.

If you are using Win98 guest make sure that 16bit DMA for SoundBlaster is
set to 5.

There might be regressions since code was changed heavily to accomodate
different/multiple sound cards (none are included in this patch, hopefully
that would change soon)

Three backends are included, they can be selected via environment
variable, i.e.:

QEMU_AUDIO_DRV=oss|sdl|wav

WAV driver will produce `qemu.wav' in current working directory.

Applying this patch and manually setting Win98 DMA to 5 has my sound worrking 
in both 98 and XP. 

Thanks a heap for your efforts, Malc.

Hi Malc,

    No luck for me; Win98 guest 'sees' the card OK now (patch applied to
latest snapshot) but no sound arrives on the host from the act of
playing a sound in the guest :(   Perhaps something odd on my setup?  As
a side note, applying the patch appears to break the compile for the ppc
target in ppc-softmmu/:
g++ -Wall -O2 -g -fno-strict-aliasing -fomit-frame-pointer  -I.

Malc,

    Definitely seems to be something wrong with my setup; with
QEMU_AUDIO_DRV set to either oss or sdl I get no output, but if it's set
to wav the qemu.wav file is generated correctly and upon playback
contains the correct sounds...

Cheers,
D

Hi All,

    Found the problem (or at least, found the area that it's in); it's
tied to the oss driver used for this laptop in the 2.6 kernel.  I went
back to a 2.4 series kernel and the sound is perfect, but, of course,
the emulation for qemu is now ~much~ slower *sighs* (I didn't realise
just how much of a performance boost 2.6 was giving me!).  Ah well,
can't have everything, can we?  :)   Alsa sound works perfectly in 2.6,
but myself not really understanding the audio code in qemu at all and
not being particularly familiar with alsa I'm afraid that I'm not the
person to try coding up an output driver for it...  :-/  *looks around
hopefully*  ;)

Hi All,

    Found the problem (or at least, found the area that it's in); it's tied
to the oss driver used for this laptop in the 2.6 kernel.  I went back to a
2.4 series kernel and the sound is perfect, but, of course, the emulation
for qemu is now ~much~ slower *sighs* (I didn't realise just how much of a
performance boost 2.6 was giving me!).  Ah well, can't have everything, can
we?  :)   Alsa sound works perfectly in 2.6, but myself not really
understanding the audio code in qemu at all and not being particularly
familiar with alsa I'm afraid that I'm not the person to try coding up an
output driver for it...  :-/  *looks around hopefully*  ;)

Malc,

    Definitely seems to be something wrong with my setup; with
QEMU_AUDIO_DRV set to either oss or sdl I get no output, but if it's set to
wav the qemu.wav file is generated correctly and upon playback contains the
correct sounds...

Cheers,

The code was just commited that enables "polling" audio mode (oss and
alsa), it's also unconditionally enabled now to obtain some testing
coverage, so please give it a whirl, feedback is welcome.

Hello,

At http://www.boblycat.org/~malc/code/patches/qemu/ you will find latest
(21_aqemu) audio patch.

New things relative to previous one:

  1. ALSA failure to set the format is no longer considered to be a
     hard error, in this situation ALSA is queried for the format it
     deems acceptable and work with that (On this PPC Linux box ALSA
     always returns EINVAL when asked for S16_LE but merrily works with
     the default - S16_BE)

  2. Added support for 32bit per sample formats

  3. Intel Controller Hub N Function 7 AKA AC'97

New things relative to the CVS:

   1. All of the above

   2. EsounD driver by Frederick Reeve
      (If someone wants aRts driver (s)he is welcome to do it, the task
       is mostly renaming the identifiers and linking with libartsc)

Now to some mildly amusing performance observations. [1]

QEMU running Slackware 11.0 (Kernel 2.4.33) on PPC 7447A 1.3Ghz
demonstrated that:

i810_audio [2] is faster than es1370
snd-intel810 is on par with snd-ens1370

i810_audio and es1370 blow snd-intel810 and snd-ens1370 right out of
th water.

The difference is toned down on Athlon 1G - where QEMU has a luxory of
using KQEMU, but nevertheless.

Perhaps the situation is improved in latest ALSA incrarnations, i don't
know.

[1] Observations courtesy http://www.boblycat.org/~malc/apc/

[2] i810_audio might, and usually does, require setting the `clocking'
     parameter upon module installation

latest (17h_aqemu at the time of this writing) audio patch. Changes
are as follows:

1. Cosmetics (Thanks to Mike Nordell)
2. Fix of several SB16 commands (mainly related to Sierras audblst.drv)
    (Thanks to rozojc for rising this topic on users forum)
3. Workaround for FreeBSDs incorrect handling of SNDCTL_DSP_OSPACE ioctl
    (Big thanks to Juergen Lock for lending me a shell on his box to debug
     the issue)

Been there. Those FAQs and HOWTOs are enough to maybe write a wav player,
the general documentation quality of ALSA leaves alot to be desired.
To set the record straight i did the driver out of curiosity and learned
enough to have no desire continuing it.

look at alsa homepage, there are tons of links to developer FAQs/HOWTOs.

[Qemu-devel] Audio

[malc]

At http://www.boblycat.org/~malc/code/patches/qemu/index.html you will
find latest audio patch (13_aqemu). Highlights of the release:

a. ES1370 emulation
b. ADC support (only for ES1370)
c. ALSA driver
d. Evil adlib hack replaced with less evil one (good for Windows hosts)
e. Internal cleanups

There are following issues:

Playing audio through ES1370 under Windows guests is much more
expensive than under Linux.

No UART support for ES1370, no ADC support for SB16, no gameport
support for either.

ADC on non-linux guests is only available through FMOD audio driver
(be aware that current version of FMOD - 3.74 has a bug that prevents
ADC from working on Linux, this should fixed in 3.75 which is expected
sometime in the near future).

ALSA driver could have been better, i guess, but given state of ALSA
documentation this is not terribly surprising, if you are an ALSA
expert by all means fix it.

Let me reiterate, are you certain that the SB16 driver is installed on the
guest at all? I am not familiar with XP, but guess you should install it
manually.

The web page hosting the patch tells about QEMU_AUDIO_DRV pretty bluntly.

You are most certainly running ALSA (with OSS emulation).

Again, if XP can not recognize SB or driver is not installed at all, no
amount of tweaking of your host audio will do much good. (Partly it's
mistake on my part to ask you to try different host audio drivers, sorry,
i wasn't reading your original message careful enough)

I'm not sure if other guests produce audio.  Know how to test this
with the dsl iso?

I wasn't aware of QEMU_AUDIO_DRV.  I tried setting it to "sdl" before
starting qemu, and still XP ended up with no audio device.

Another thought. QEMU's SB16 is non PNP ISA device, so perhaps, you should
try to install device driver manually, make sure that settings are set
correctly IRQ=5 DMA8=1 DMA16=5, maybe then it'll work.

What sound card and audio system (oss, alsa) do you use? Other guests
produce audio? Have you tried alternate audio output drivers
(QEMU_AUDIO_DRV=wav or sdl)? And also, i do not have WinXP license, so
there's relatively little i can do about it. Anybody else is having
problems with XP?

I added a little change to work on Windows and back ported to 0.5.5.

http://www.h7.dion.ne.jp/~qemu-win/download/qemu-20040621-6_aqemu.patch.gz
http://www.h7.dion.ne.jp/~qemu-win/download/qemu-0.5.5-6_aqemu.patch.gz

I tested to play .wav sound in Red Hat 7.2 guest.
modprobe sb io=0x220 irq=5
play test.wav

They work well on Windows2000 and WindowsMe. A little thing is that I hear a
little noise two times when a sound starts. It seems that it occurs when a
device is opened.

But the problem is that it doesn't work on Fedora Core 1 host with these
patches. I tried to find out what was the problem but I couldn't. It seems
that oss and sb16 work....
I can hear a sound and almost the same noise when I used original 0.5.5
source.

	It detects now, but is mute and acts like the interrupt isn't
working correctly.  Getting closer, though :)  Thanks!

Hello,

Patch that fixes audio for Win98 guest and also workarounds SDL deadlock
is now available at:

http://www.boblycat.org/~malc/code/patches/qemu/index.html

Quite a few things have changed so it can introduce regressions. Would
be nice if someone with big-endian host can verify(or fix) audio output.
