First I thought about not responding here but decided otherwise. May I
ask you first if you did a basic search about this issue before posting
here?

If I look for "'PaAlsaStreamComponent_GetAvailableFrames( self,
&framesAvail, xrun )' failed" the first result is a link to the Gentoo
forum [1] which suggests the installation of alsa-oss to fix this issue.

So did you look for the issue and put some effort into it before posting
here? No offense but you post a lot of questions about problems you have
here which in my opinion are often solved with little effort you could
have done yourself. So the thought pops up that you are just lazy and
let others do the work. Also I only every see you asking questions but
never trying to answer questions of others.

Explaining your problem and also stating what you already tried or where
you have looked for a solution will avoid that people get that
impressions and they may be more helpful. Or the post is completely
unnecessary because you solved it yourself after 5 minutes of
investigation which saves the time of all the other list participants.

Just a friendly recommendation from me as over time this annoys me a
little and probably I am not the only one here. If people are annoyed it
is unlikely for them to help. So help yourself to make others help you.
