Creative surround regression=> assertion, alsa-time report for broken sound drivers. and more..

[gourgi]

I know "Creative doesn't like Open Source -- there are no docs available. If you buy Creative it is hence a bit your own fault. "

It is said clear enough and very often by lennart
i hope this bug report can make my creative soundblaster live! 24bit (snd ca0106) rock and surround sound without problem!!

my stereo sound is acceptable using pulseaudio 0.9.15-test3 but when i enable surround -> assertion and disaster :(
also my volume controls have no meaning from 0%-60% , and after 60% the sliders become of usage and increasing/decreasing volume level works.
Below i attach logs and config for:
1) default setup , config and logs for stereo output
2) config and logs for surround (5,1) output.
3) related alsa bugs
4) alsa-time.c output
5) disabling glitch-free
5) a working ubuntu 8.10 PulseAudio surround setup

related alsa bug reports about sample-rate, No PCM , No Mic found :
# 0003407
# 0001837
# 0004398 ( "Mic" problem reported by me, a lot of pulse-related questions are asked by Raymond, i think you should look at it! )
# 0002939

i changed the daemon.conf to 6 channels and sample-rate to 48000 as this is the right sample rate for my card (alsa bug tracker's bug report #0003407, #0004398 )

$ cat /etc/pulse/daemon.conf

and now the syslog and userlog shows this errors:

If more info/testing is needed please guide me !

as suggested in the logs something in the driver is buggy
(alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_ca0106'. Please report this issue to the ALSA developers.)
how i should report this ? title and description that can be meaningfull ???
