Please report this but to the ALSA bug tracker. https://bugtrack.alsa-project.org/alsa-bug/ See the link from http://alsa-project.org/ I think the problem you describe is that the emu10k1 has a single mute control for both channels, so you do not have the left/right mute. You need to do a test first to find out if the is separate left/right mute or if they are separate. If there is only one, the "SND_MIXER_SCHN_FRONT_LEFT" controls both channels. Maybe it would be sensible to change the alsa-lib api so either SND_MIXER_SCHN_FRONT_LEFT or SND_MIXER_SCHN_FRONT_RIGHT will control both left/right is the mute control is shared. > > Now they both are working but there's one thing that seems to be going > wrong.
