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: 06-22-2006 06:30 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? ====================================================================== ---------------------------------------------------------------------- Raymond - 06-21-06 14:25 ---------------------------------------------------------------------- alsamixer expect index controls are continuous, but the driver implemented in non-standard way (i.e. Deemphasis appear between DAC volume controls).
