On my frontend I have a Soundblaster Audigy SE, which installed just nicely. I had to unmute the channels via alsamixer, and then I got sound. I'm not using SPDIF, simple sound output is enough for me.

One problem I havn't been able to resolve still remains: I can't change the volume level with my remote! The volume meter shows up on the TV screen and it is gong up and down as it should, but the actual volume level stays at the level I set it with alsamixer.

I have tried different variations of the settings, both "ALSA:default" and "/dev/dsp" as output device, and "default" and "/dev/mixer" as mixer device - none work. I was already planning on changing the volume controls from lirc to amixer +-2% -commands.

Does anyone have any ideas on how to get it working? If so, I would once again be ery grateful of any possible hints...

Try changing "Mixer Controls:" in Setup -> General -> Audio. Some of my audio chipsets I have that set for PCM, others Master.

Thanks slowtolearn! Unfortunately that didn't work. However, I got the result I wanted by changing the .mythtv/lircrc file as follows:

Code:
begin
    #prog = mythtv
    prog = irexec
    button = vol_down
    #config = [
    config = amixer -c 0 set "Channel Front" 2%-
    repeat = 2
end

begin
    #prog = mythtv
    prog = irexec
    button = vol_up
    repeat = 2
    #config = ]
    config = amixer -c 0 set "Channel Front" 2%+
end


man amixer helped a lot.
