Hello, I hit the following (Ubuntu natty): pmeerw at pmeerw-pc2:~/Desktop$ pulseaudio E: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! E: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. E: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. alsa-time-test hw:0 outputs the following ... 477445 477433 137324 6253 4220 196 4 1 3 477450 477433 137324 6254 4219 197 4 1 3 496587 496584 156371 6255 5058 -642 4 1 3 alsa-time-test: alsa-time-test.c:220: main: Assertion `(unsigned) avail <= buffer_size' failed. Aborted 00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05) is this still relevant? http://www.pulseaudio.org/wiki/BrokenSoundDrivers regards, p. -- Peter Meerwald +43-664-2444418 (mobile)
