[mythtv-users] Sound Problem in Mythfronted

[Or Duek]

Could you output your settings and the output of a playback where the
problem occurs, starting mythfrontend with -v audio

Does the problem always occur, or is intermittent ?

After a reboot, does it occur immediately or only later on?

Ok, I'm really sorry. Those things are probably a little bit hard on me.
I attach the beginning of terminal output with what looks like my settings:

I hope it is better.
About my setting:
I use AverMedia Volar Black HD as my DVB-T dongle.
I'm using Mythbuntu 10.04.
I have alc1200, intel integrated sound card which is connected to
a receiver using adapter from headphone connection to RCA.

Thank you very much for your help.
