Hi all,
I am using an onboard Audigy LS with the ca0106 driver on Fedora Core 6.
This is on a mythtv box and I would like to use mythtv's internal volume
controls, but of course I don't have a Master control. I first tried
just using softvol to create a Master control and that did not work. I
then read that you need to be able to run aplay on the device from 2
consoles simultaneously in order to use softvol. I could not, so I then
set up dmix. I can now run 'aplay -Dduplex file.wav' from 2 different
consoles simultaneously just fine. I can also control the volume with
'amixer set "Master" 90%' and the volume is correctly set. In mythtv I
have it set to use the internal volume controls and control Master and I
have the mixer set to /usr/bin/amixer. Sound comes through fine but I
can not control the volume with the remote. Also note that with my
new .asoundrc xmms no longer has sound other than 'clicking'. I can
deal with that later as for now I just want to control the volume with
my remote. Here is the pertinent info:
