Hi

I have been trying to get sound to work correctly on my Acer Apire 8930G with no success. I have already tried to get a resolution at the forum. The user who was helping me there suggested that i file a bug.

I am pasting my findings here (the entire thread is available at https://forums.opensuse.org/english/get-technical-help-here/multimedia/48437...)

I ran also-info.sh and my output is at http://www.alsa-project.org/db/?f=83678a06bd03818ed55d40674cd315453af74cee

When i run speaker-test -c6 -Dplug:surround51 -t wav -l1, i get a segmentation fault! ----------------------------------------- speaker-test -c6 -Dplug:surround51 -t wav -l1

speaker-test 1.0.26

Playback device is plug:surround51 Stream parameters are 48000Hz, S16_LE, 6 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 22 to 87381 Period size range from 11 to 43690 Using max buffer size 87380 Periods = 4 was set period_size = 21845 was set buffer_size = 87380 Segmentation fault ----------------------------------

When I run speaker-test -c6 -l5 -twav, this is what i get

speaker-test -c6 -l5 -twav

speaker-test 1.0.26

Playback device is default Stream parameters are 48000Hz, S16_LE, 6 channels WAV file(s) Rate set to 48000Hz (requested 48000Hz) Buffer size range from 32 to 349525 Period size range from 10 to 116509 Using max buffer size 349524 Periods = 4 was set period_size = 87381 was set buffer_size = 349524 0 - Front Left 4 - Center 1 - Front Right 3 - Rear Right 2 - Rear Left 5 - LFE

I hear sound for all the channels except LFE. However, this is how it is - most sounds from all speakers Front left - 'Front left' is heard from Rear left and Front left Front Center - 'Front Center' is heard from Rear Right and Front Center Front Right - 'Front Right' is heard from the Sub Woofer (Tuba in this case) Rear Right - 'Rear Right' is heard from Front Right but it is barely audible Rear Left - 'Rear Left' is heard from Front Left but is barely audible

I noticed in the also output that the output is shown as Mono. Should it not be Stereo? There is definitely something wrong here. I have also tried changing the model in options and the index and turning on enable_msi. Some of them does not produce any sound and some do but none in the right channels.

The segfault of speaker-test is basically irrelevant from the silent speaker issue. We need to track it in a separate bug. And unless you pass -Dsurround51, only the stereo output will be chosen and 6 channels are reduced implicitly to 2 channels. But, this is also irrelevant. So, you are testing with the speaker outputs and none of the speakers works? It doesn't work even if you run with speaker-test -c2 -twav, correct? Also, what about the headphone output? The openSUSE 12.3 kernel is a bit outdated, so it's harder to debug. It'd be appreciated if you can test the 3.9.y stable kernel, which is available at OBS Kernel:stable repository. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
