Comment 33 for bug 367671

It's an interrupted syscall -- there is no result... And the for loop only repeats on EINTR.

I take it that no support, or at least help, will be forthcoming from the Ubuntu side?

Even though the lead PA developer seems like a smart guy who understands real-time quite well, I'm sorry to say that PA is a stability and usability nightmare, and it has always been so. See the myriad of guides on removing PA from Ubuntu installs.

I think the problem is that PA developers put a low priority on making the software "just work" for the user. They are, however, quite happy to explain what the "right thing" is, how to contact the non-responsive ALSA developers, how to invest hours upon hours debugging Pulse etc.
