Have spend a lot of time searching many threads but not seen a solution
Have installed mythtv to kbuntu (32 bit) and configured the backend with HDHomerun and receive video but no sound The ] key brings op the volume bar but sits at 0 and will not adjust.

However caffeine and he HDhomerun conf GUI viewer play the video and sound perfectly.

Strangely, in setting up the backend I never saw an entry for alsa or mixer, it appears somethimg is missing there for HDHomerun, although those are present when I added an entry for a Hauppauge 950Q USB tuner. Can not get this source to work as yet so have not seen the sound problem there.

The speaker test
speaker-test -c 2
also works as do the login/logout sounds and the test in system settings/multimedia.

alsa -l reports

After considerable experimentation with the TV setup/General I now have sound. Had to set Audio out to /dev/dsp and the sound worked, Alsa default fails. Also has to change the mixer parameters since the F9/10/11 keys did not work. Set the mixer device too software and the Mixer controls to Master. This for a mainboard with Realtek sound chip on board. 1080p video on the Samsung P2370 monitor or the Viewsonic VX2235 1680x1050, ATI 4670 display adapter.
