Summary: Exaudio produces noise on all speakers for 5.1
channels
Description:
I am using a soundblaster extigy with ALSA ver. 1.0.9b and am happy to say
that stereo sound works find and that all 6 speakers can produce some
sound.
With more than 2 channel output, I experience problems. speaker-test,
which
works for 1 and 2 channels, results in a hissing/crackling for 3,5,6
channels, which changes in pitch depending on the number of channels. For
4
channels, it loops, producing the following output
speaker-test 0.0.8
Playback device is extigy
Stream parameters are 48000Hz, S16_LE, 4 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 8192
Period size range from 48 to 4096
Periods = 4
Buffer time size 2525
To choose buffer_size = 8192
To choose period_size = 2048
was set period_size = 2048
was set buffer_size = 8192
Unable to set hw params for playback: Invalid argument
Setting of hwparams failed: Invalid argument
Rate set to 48000Hz (requested 48000Hz)
[ The "Rate set to ..." part is repeated continuously ]
Setting my capture device to mixer, I was able to record the output with
arecord -c 6 -f dat -r 48000 /root/speaker-test-6ch.wav . The distortion
is
still present when playing the file, forcing 2 channels in aplay.
In addition to using speaker test, I tried using the route plugin to
isolate
the rear channels. When I route to any channel, I can hear the same output
on
all 5 (not sure about Woofer) channels, no matter which channel I route
to.
Here is the relevant setup:
pcm.route1 {
type route;
slave.pcm "extigy";
slave.channels 6;
ttable.0.0 1.0;
}
The music that I played had similar distortions like the one for speaker
test
and played considerably slower than when player with 2 channels. Again I
could record and replay the effect. The setup was slightly different in
order
to route the stereo channels to all 6 speakers.
For routing with 4 slave channels, I get a failure (as expected), this
time
with the output:
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,

This is all the relevant bits that I can think of at the moment. Thank you
for
reading this far. If anybody thinks it is important to get the recorded
files, I am happy to sent them. I am grateful for any nudge on what I am
doing wrong with my setup.

Sorry, I did not mention it. Everything with 2 speakers works fine.
Playback and Recording.
I assumed that the card did not support 4 speakers. As far as I understand
it, the channel routing mode can be used to select only 4 channels for
playback (and for that matter the routing plugin). If I run speaker-test
then the channel routing mode does turn off certain speakers when I cycle
through the different values (don't know if this is relevant though).
As far as the recording is concerned, I recorded from the "mixer" capture
setting and that should work no matter how many channels I set, shouldn't
it?
----------------------------------------------------------------------
Clemens Ladisch - 06-24-05 17:22
----------------------------------------------------------------------
When you're recording with the "mixer" setting, you probably get the two
front channels.
What I meant to say above was: if you record two channels while playing
more than two channels, the distortion should still be present in the
first two channels you've recorded. Is it? Could you upload a _small_
test file?

it is

I have managed to get surround sound somewhat working with the card now. I
cannot use 6 channel individually but I figured out how to pass an AC3
stream to the card. This will then produce sound on all speakers.
The main issue that still remains is that speaker-test (and any other
program) sees the card as being able to do 6 channel when it really cannot
output to these channels individually. I suggest that the number of
speakers is set to 2, since this is the only setting that produces good
output on the card.

Summary: Exaudio produces noise on all speakers for 5.1
channels
Description:
I am using a soundblaster extigy with ALSA ver. 1.0.9b and am happy to say
that stereo sound works find and that all 6 speakers can produce some
sound.
With more than 2 channel output, I experience problems. speaker-test,
which
works for 1 and 2 channels, results in a hissing/crackling for 3,5,6
channels, which changes in pitch depending on the number of channels. For
4
channels, it loops, producing the following output
speaker-test 0.0.8
Playback device is extigy
Stream parameters are 48000Hz, S16_LE, 4 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 8192
Period size range from 48 to 4096
Periods = 4
Buffer time size 2525
To choose buffer_size = 8192
To choose period_size = 2048
was set period_size = 2048
was set buffer_size = 8192
Unable to set hw params for playback: Invalid argument
Setting of hwparams failed: Invalid argument
Rate set to 48000Hz (requested 48000Hz)
[ The "Rate set to ..." part is repeated continuously ]
Setting my capture device to mixer, I was able to record the output with
arecord -c 6 -f dat -r 48000 /root/speaker-test-6ch.wav . The distortion
is
still present when playing the file, forcing 2 channels in aplay.
In addition to using speaker test, I tried using the route plugin to
isolate
the rear channels. When I route to any channel, I can hear the same output
on
all 5 (not sure about Woofer) channels, no matter which channel I route
to.
Here is the relevant setup:
pcm.route1 {
type route;
slave.pcm "extigy";
slave.channels 6;
ttable.0.0 1.0;
}
The music that I played had similar distortions like the one for speaker
test
and played considerably slower than when player with 2 channels. Again I
could record and replay the effect. The setup was slightly different in
order
to route the stereo channels to all 6 speakers.
For routing with 4 slave channels, I get a failure (as expected), this
time
with the output:
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,

This is all the relevant bits that I can think of at the moment. Thank you
for
reading this far. If anybody thinks it is important to get the recorded
files, I am happy to sent them. I am grateful for any nudge on what I am
doing wrong with my setup.

When you're recording with the "mixer" setting, you probably get the two
front channels.
What I meant to say above was: if you record two channels while playing
more than two channels, the distortion should still be present in the
first two channels you've recorded. Is it? Could you upload a _small_
test file?
----------------------------------------------------------------------
andersin - 06-24-05 17:47
----------------------------------------------------------------------
I added two files, each representing one complete iteration of the
speaker-test program. I hope the files are small enough.

This device does neither support playback with four channels, nor recording
with any other number than two channels.
Is the distortion still present in a two-channel file that you record from
"hw:X"?

Sorry, I did not mention it. Everything with 2 speakers works fine.

works for 1 and 2 channels, results in a hissing/crackling for 3,5,6
channels, which changes in pitch depending on the number of channels. For
4
channels, it loops, producing the following output
speaker-test 0.0.8
Playback device is extigy
Stream parameters are 48000Hz, S16_LE, 4 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 96 to 8192
Period size range from 48 to 4096
Periods = 4
Buffer time size 2525
To choose buffer_size = 8192
To choose period_size = 2048
was set period_size = 2048
was set buffer_size = 8192
Unable to set hw params for playback: Invalid argument
Setting of hwparams failed: Invalid argument
Rate set to 48000Hz (requested 48000Hz)
[ The "Rate set to ..." part is repeated continuously ]
Setting my capture device to mixer, I was able to record the output with
arecord -c 6 -f dat -r 48000 /root/speaker-test-6ch.wav . The distortion
is
still present when playing the file, forcing 2 channels in aplay.
In addition to using speaker test, I tried using the route plugin to
isolate
the rear channels. When I route to any channel, I can hear the same output
on
all 5 (not sure about Woofer) channels, no matter which channel I route
to.
Here is the relevant setup:
pcm.route1 {
type route;
slave.pcm "extigy";
slave.channels 6;
ttable.0.0 1.0;
}
The music that I played had similar distortions like the one for speaker
test
and played considerably slower than when player with 2 channels. Again I
could record and replay the effect. The setup was slightly different in
order
to route the stereo channels to all 6 speakers.
For routing with 4 slave channels, I get a failure (as expected), this
time
with the output:
Playing WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz,
Stereo

BUFFER_TIME: (170666 170667)
BUFFER_SIZE: 8192
BUFFER_BYTES: 32768

This is all the relevant bits that I can think of at the moment. Thank you
for
reading this far. If anybody thinks it is important to get the recorded
files, I am happy to sent them. I am grateful for any nudge on what I am
doing wrong with my setup.

What are the contents of /proc/asound/cardX/stream0 while you're playing
with 6 channels?

Summary: Exaudio produces noise on all speakers for 5.1
channels
Description:
I am using a soundblaster extigy with ALSA ver. 1.0.9b and am happy to say
that stereo sound works find and that all 6 speakers can produce some
sound.
With more than 2 channel output, I experience problems. speaker-test,
which
works for 1 and 2 channels, results in a hissing/crackling for 3,5,6
channels, which changes in pitch depending on the number of channels. For
4
channels, it loops, producing the following output
speaker-test 0.0.8
