No rear/center sound

[Rafal Zawadzki]

My soundcard is:
0000:00:11.5 Multimedia audio controller: VIA Technologies, Inc. VT8233/A/8235/8237 AC97 Audio Controller (rev 60)

I don't hear sound from rear/center speaker (using mplayer -6, playing aplay 6 channels sounds).

Note: the original reporter indicated the bug was in package 'alsa'; however, that package was not published in Ubuntu.

I have the same problem with an hda-intel card.
Product/vendor ID: 8086:27d8 (rev 01)

[Almanildo (audunskaugen)]

Running feisty of course

[Selmi (selmi)]

i have same problem, so i am adding myself to mail notification...

[cj100570 (cj100570)]

same issue here on feisty. it's made me go back to edgy since i play a lot of vovies on my system and absolutely have to have this.

[Ralf Nieuwenhuijsen (ralf-nieuwenhuijsen)]

Same here! Same card, same issues.

[RJ Clay (rjclay)]

You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

[cj100570 (cj100570)]

Everything works in 8.04.

for me it also works with 8.04, but i had to connect rear speaker as center/lfe and center/lfe as rear, otherwise sound was played incorrectly. it seems that default connectors (also marked with color) in windows xp drivers match hardware and alsa has it somehow changed.
