[mythtv-users] Change volume when watching TV through X

[forum at pdebrabander.nl]

I've setup Mythtv on FC1 and watch TV on my television. When i change the
volume the volumebar moves, but the output stays the same.
Is it possible to change the volume output through the televisionspeakers by
the remote control.
For reference, i use the PVR350 and an I810 soundcard.

Another option could be the sound of the TV trough the soundcard just like
listening to CD or watching DVD/Movie

Thanks
