Title:
pcm_pulse.c:275: pulse_write: Assertion `pcm->last_size >= (size *
pcm->frame_size)' failed. (Intrepid & pulseaudio_0.9.11-0ubuntu1~ppa3
- TheMuso PPA)
Status in ALSA driver:
Invalid
Status in PulseAudio sound server:
Fix Released
Status in alsa-plugins package in Ubuntu:

Status in pulseaudio package in Ubuntu:
Fix Released
Bug description:
The pcm_pulse plugins do not work correctly *for some ALSA
applications* with PulseAudio 0.9.11 from TheMuso's repository (I am
using the patched version, see bug #262322). Applications with native
PulseAudio support work correctly.
System: Intrepid i386 (w/latest updates) & pulseaudio 0.9.11-0ubuntu1~ppa3
Sound card: 00:1f.5 Multimedia audio controller: Intel Corporation 82801EB/ER
(ICH5/ICH5R) AC'97 Audio Controller (rev 02)
Example 1:
conn@dimension:~$ mplayer /usr/share/example-content/ubuntu\ Sax.ogg -ao
pulse
<snip>
AO: [pulse] 44100Hz 2ch s16le (2 bytes per sample)
Video: no video
Starting playback...
A: 1.7 (01.6) of 26.0 (25.9) 0.5%
<snip>
Example 2 (asoundconf set-pulseaudio has been enabled):
conn@dimension:~$ mplayer /usr/share/example-content/ubuntu\ Sax.ogg -ao alsa
<snip>
AO: [alsa] 44100Hz 2ch s16le (2 bytes per sample)
Video: no video
Starting playback...
mplayer: pcm_pulse.c:275: pulse_write: Assertion `pcm->last_size >= (size *
pcm->frame_size)' failed.
<snip>
Expected results: both examples play sound correctly (same behaviour as
0.9.10)
Actual results: Example 1 plays correctly, while Example 2 fails to play an
audio stream, with the error output above.
Edit: At first I thought that all ALSA applications suffered from this
problem, but I was mistaken.
Confirmed to cause assertion failures: Skype, mplayer
Confirmed to work correctly (sound plays, no assertion failures or warnings):
GStreamer ALSA backend (Totem, Rhythmbox, etc.), flashplugin-nonfree
10.0.0.569ubuntu1 without libflashsupport (not yet in Intrepid, available in my
PPA).
Other: VLC using ALSA plugin (no assertion errors, listed as client in Volume
Control, but it plays silence).
