[Solo0815]

I upgraded from  around 0808 (don't know exactly) to 0309 or newer and I got sometimes crackling sound in videos, LiveTV and recordings. In the log there are many lines with

Code:

I'm back on 0808 and will do more tests. Has anyone the same problem or a clue, what is causing this underun?
