A NOTE has been added to this issue. ====================================================================== <https://bugtrack.alsa-project.org/alsa-bug/view.php?id=321> ====================================================================== Reported By: 64bitten Assigned To: ====================================================================== Project: ALSA - driver Issue ID: 321 Category: PCI - ice1724 Reproducibility: always Severity: minor Priority: normal Status: acknowledged Distribution: gentoo Kernel Version: 2.6.6 ====================================================================== Date Submitted: 06-02-2004 08:09 CEST Last Modified: 06-20-2006 23:29 CEST ====================================================================== Summary: Left front channel always muted on boot Description: ice1724 (M Audio Revolution 7.1 in my case) always restores the mixer settings at boot, but the left front channel is muted regardless. The fix is to run alsamixer and adjust the slider again. This forces the channel to unmute. Should I be worried "amixer scontrols" reports everything as "Mono" as well? ====================================================================== ---------------------------------------------------------------------- goldenfish - 11-18-05 21:03 ---------------------------------------------------------------------- I have the same problem with my Revo7.1 on the left speaker. I was created diff from proc filesystem. Test options: alsamixer cp -ar /proc/asound procfs_before/ alsamixer --> DAC volume 20->22 and 22->20 cp -ar /proc/asound procfs_after/ diff -Nru proc_before proc_after diff is attached. ---------------------------------------------------------------------- effie - 06-20-06 23:29 ---------------------------------------------------------------------- Well, I have the muting problem too (M-audio Revolution 7.1). In most cases it is indeed the left channel that stays muted. In my case it seems that the first channel that is tried to be unmuted, whichever it is, remains silent although the new volume value is set in the mixer. When I boot up my computer (with alsa volume restore script disabled) and try to unmute the left channel first with amixer cset numid=20 40, that channel remains silent (although the new value is reported by the mixer). When I do the right channel first (numid=21), the right one remains silent. The second change of volume always works, whether it is the same channel as the first one or another (providing you really change it, to a different value, not the same). So the very first change of volume seems to be the problem (at least in my case). Note: I haven't tested it with the rear channels, as I don't use them (headphones) :).
