[pulseaudio-tickets] [Bug 50324] pulseaudio continuously creates and frees input streams

--- Comment #13 from Dirk Thierbach <dthierbach at gmx.de> ---
I'm experiencing the same problem, not with Chrome (which I don't use), but
with several ALSA clients. All Pulseaudio clients (including paplay) work.
aplay also works for some reason; alsaplayer, timidity and mocp are not usable
(sound is like what you get on fast forward). The -vvvv pulseaudio log looks
very similar (extract for "alsaplayer" below).

This is on Debian/Sid, pulse packages version 5.0-2. It worked before, some
upgrade (I didn't run into that problem immediately, so I don't know which one)
broke it.

Please tell me if you need the full log, or other details.
