[mythtv-users] envy24 sound and internal volume controls

[Jeremy]

Is there anyone out there using an envy24 based setup (M-Audio,
Audiotrak) that is able to use the internal volume controls?  If I use
OSS (/dev/dsp), I get normal output but as soon as I timeshift or seek I
get Audio buffer overflows (I've tried all combinations of 'extra audio
buffering'  and 'aggressive buffering' options).  While using ALSA
(ALSA:default) I get 'unable to find control PCM',  most likely because
my card, an Audiotrak Prodigy 7.1 has no PCM control it only has a
Master and a string of digital controls.   It works fine with internal
volume controls disabled, but I really like having the internal as I
don't have to switch to the TV remote just to adjust the volume.

Any help is appreciated,
Jeremy
