Public bug reported:
On my system, I had problems with both excess CPU usage and tried to
resolve them by using a simpler resampling algorithm. However, that
resulted in crackling audio from DOSBox and Windows 3.1 games running
under Wine 1.2.x.
(Both are configured to output audio at 22050Hz, with which ALSA dmix
has no problem, and, in the case of the Windows 3.1 games, that's not
something that can be reconfigured as far as I know.)
Nothing I changed seemed to help and I was forced to return to speex-
float-1.
(As such, the pulseaudio config files in the debug dump don't represent
PA in a broken configuration... just one that consumes more CPU than I'd
like it to.)
