[Pkg-pulseaudio-devel] Bug#522598: work around to improve the situation a bit

Just a little followup. Discovered from
https://fedoraproject.org/wiki/Features/GlitchFreeAudio that following
helps the situation a bit:
The PulseAudio sound server has been rewritten to use timer-based
audio scheduling instead of the traditional interrupt-driven approach.
Timer-based scheduling may expose issues in some Alsa drivers. To turn
timer-based scheduling off, replace the line

load-module module-hal-detect

in /etc/pulse/default.pa by

load-module module-hal-detect tsched=0

After the above modification, I still get following messages in syslog:
Apr 21 20:36:31 red pulseaudio[16799]: module-alsa-sink.c: ALSA woke
us up to write new data to the device, but there was actually nothing
to write! Most likely this is an ALSA driver bug. Please report this
issue to the PulseAudio developers.
Apr 21 20:37:02 red last message repeated 14 times

but the sound chopping appears to have gone and sound plays smoothly now.
