[mythtv-users] Creative Audigy LS: please help to setup volume control to work from Myth

[Andrew Junev]

Hello,

I can't control LiveTV (or recordings) volume via MythTV. When
pressing '[' and ']' I can actually see the volume slider moving, but
the loudness itself does not change. It looks like it has something to
do with my Myth configuration, since I can control the volume via
alsamixer just fine.

Can you tell me what I have to put to the mythtv settings? I think I
tried everything but it either gave me no sound at all or a sound with
no volume control from Myth.

At the moment my Myth's Audio settings are:
Audio output device: /dev/dsp
Mixer device: /dev/mixer
Mixer Controls: PCM
