no sound watching livetv
With the new release of mythtv I felt it was time to checkout mythtv
again. Last time I set it up with 0.8 and got everything setup and
working perfectly.

This time after getting mythtv all setup, I get no audio when watching
livetv or recorded shows. When i do the test with xawtv and aplay that
is recommended in the documentation, I hear the audio correctly.
Just to be sure it wasn't a permission problem is did a "chmod -R 777
/dev/snd" but that didn't fix it.

When i go to watch livetv I get these messages from the backend.

Changing from None to WatchingLiveTV
recorder: /dev/null: error setting audio input device to
44100kHz/16bits/2channel
Could not detect audio blocksize
audio volume set to '32768'
recorder: /dev/null: error setting audio input device to
44100kHz/16bits/2channel


I have a soundblaster ensoniq and am using the latest alsa drivers on
gentoo linux. I have made no changes to my hardware setup since i had
the 0.8 release working. I have even tried reinstalling the 0.8 release
and now that doesn't work either.

I try to fancy myself as a linux expert but I am really stumped as to
what might be going on. Any help would be appreciated.

It's trying to capture audio from '/dev/null'.
Sounds like you need to re-run your backend setup. Note that when
specifying the audio capture source, you can't type, you must select from
the list.
