[mythtv-users] Problem with sound

[raptor jr]

Sometimes i have problem with the sound on LiveTV and recordings. It appears in different ways, but sometimes it is like the sound is coming from inside a metal box, or there is a echo, or the sound is delayed several times so even though only one person is talking it sounds like several people is talking and saying the same things. And it appears all of a sudden even though i haven't changed any settings or anything.
 
I really dont know how to find the problem but it is annoying. And i dont really know how to make it good again, i restart the frontend several times, i restart the recording or LiveTV, and all of a sudden it works again. I am using internal volue controls. Tried to disable that but still the same problem.
It is not tied to a recording, because recordings that i do know sounds good before sounds bad when this happends.
 
How can i debug this?
