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: 06-21-2006 06:10 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? ====================================================================== ---------------------------------------------------------------------- effie - 06-20-06 23:31 ---------------------------------------------------------------------- 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 same is true for the right one. 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) :). ---------------------------------------------------------------------- Raymond - 06-21-06 06:10 ---------------------------------------------------------------------- Please post the content of /etc/asound.state (alsactl store) Issue History Date Modified Username Field Change ====================================================================== 06-02-04 08:09 64bitten New Issue 06-02-04 08:09 64bitten Distribution => gentoo 06-02-04 08:09 64bitten Kernel Version => 2.6.6 12-17-04 03:15 K6-III Note Added: 0002845 12-17-04 06:46 herby Note Added: 0002846 12-17-04 06:51 rlrevell Note Added: 0002847 12-21-04 07:09 64bitten File Added: amixer.bad 12-21-04 07:10 64bitten Note Added: 0002896 04-09-05 17:24 jdthood Status new => acknowledged 10-20-05 02:36 sst4 Note Added: 0006497 10-20-05 05:18 Fran Note Added: 0006498 10-21-05 03:51 64bitten Note Added: 0006509 11-18-05 21:03 goldenfish Note Added: 0006758 11-18-05 21:04 goldenfish File Added: proc_changes.diff 06-20-06 22:55 effie Issue Monitored: effie 06-20-06 23:05 effie Issue End Monitor: effie 06-20-06 23:29 effie Note Added: 0010356 06-20-06 23:31 effie Note Edited: 0010356 06-21-06 06:10 Raymond Note Added: 0010382 ====================================================================== _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.sourceforge.net/lists/listinfo/alsa-devel
