Hi all,
I have a following problem with my system. I can play stereo music well
enough from my front speakers, but when I try to play 5.1 surround
sound, I only get sound from all the other speakers!
I'm running Debian testing/unstable using 2.6.12 kernel (x86) with
Soundblaster Live! 5.1 installed and have installed ALSA from Debian
reposity. alsa-lib version seems to be 1.0.10. More system details can
be found from the end of the email.
After configuring ALSA with alsaconf I'm able to play stereo music
(using, say, XMMS) from my front speakers. I can control the volume from
alsamixers Wave slider and I also get music from all the other speakers,
if I want to, with Wave Center, Wave LFE and Wave surround sliders.
When I try to play surround sound, however, the front speakers stay
silent. This happens both with DVD playback and with speaker-test. When
running speaker-test, I see
[EMAIL PROTECTED]:~$ speaker-test -Dsurround51 -c6
speaker-test 0.0.8
Playback device is 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 64 to 16384
Period size range from 16 to 16384
Periods = 4
Buffer time size 2525
To choose buffer_size = 16384
To choose period_size = 4096
was set period_size = 4096
was set buffer_size = 16384
0 - Front Left
4 - Center
1 - Front Right
3 - Rear Right
2 - Rear Left
5 - LFE
but I don't hear channels 0 and 1. Others are fine. I have tried
unmuting and setting all possible sliders to maximum in the alsamixer,
but nothing has helped. Surround, center and LFE sound volumes can be
controlled from respective sliders correctly.
I have tried to Google for the solution and search from the mail list
archives, but nobody seems to have same problem. :-] I would be grateful
if someone could help somehow.
Regards,
Esko Arajärvi
Below some more information which maybe could help pinning down the problem.
