FM801 sound chips doesn't play nice songs

Retested in Ubuntu 10.04 i386 beta. HW is still broken. Audio buffers are played in random order or lost; difficult to say.I hear sound but it is strange.

Song of length 2:53 played in 1:28, this points to the buffer lost. I cannot hear shift in frequency.

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.

Thank you for taking the time to report this bug and helping to make Ubuntu better. We need some more information from you before we can start working on this bug.

Please include the information requested from the "Reporting Sound Bugs" section of https://wiki.ubuntu.com/DebuggingSoundProblems as separate attachments.

If you are using Jaunty or later this information can be gathered for you automatically using the command apport-collect -p alsa-base 463685

First, I upgraded my system from U9.10 to U10.04
Second, problem with sound are not fixed in U10.04

This bug also affects me with 12.04. How can I send my config?

Status changed to 'Confirmed' because the bug affects multiple users.

does it help if you change the periods_min from 1 to 2 if it has two buffers ?

#define FM801_PLY_BUF1 0x0c /* Playback Bufer I */
#define FM801_PLY_BUF2 0x10 /* Playback Buffer II */

WOW!!
This bug was reported in 2009, and almost 10 years later we have no solution!!
It's getting very difficult to find a cheap PCI sound card that works fine with Ubuntu or any other Linux distribution.
Would a SoundBlaster Live work fine??
Talk about market reserve!!!
