Comment 3 for bug 463685

I created several audio files:

2646710 2010-03-27 22:05 test26.wav
2616876 2010-03-27 22:15 test26_u1004.wav
3885100 2010-03-28 20:20 test26_u0910.wav
5648428 2010-03-27 22:28 test26_u0804.wav
5685324 2010-03-28 18:29 test26_vl060.wav
5546060 2010-03-28 18:36 test26_win_hp.wav
5967948 2010-03-28 19:44 test26_win2k.wav

test26.wav is audio file created in Audacity; it has length 30s and contains silence, sine 440Hz and chirp from 220Hz to 8800Hz.
I played this file in several OS and recorded audio at different PC. u0804, u0910 and u1004 are U10.04 (OK) U09.10 (very bad) and U10.04 (bad), win2k is sound played under Win2k. vl060 is Vector Linux 6.0. win_hp is played under windows but different HW with different sound card; only for a reference.
U8.04 plays the best sound, even better than W2k (difference is visible in audio analyser, like Audacity). Sample from U10.04 clearly demonstrates that some buffers are lost.
