#497: Creative surround regression=> assertion, alsa-time report for broken
sound
drivers. and more..
----------------------------------------+-----------------------------------
Reporter: gourgi | Owner: lennart
Type: defect | Status: new
Priority: normal | Milestone:
Component: daemon | Severity: normal
Keywords: creative, ca0106, surround |
----------------------------------------+-----------------------------------
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. "
[[BR]]
It is said clear enough and very often by lennart
[[BR]]
i hope this bug report can make my creative soundblaster live! 24bit (snd
ca0106) rock and surround sound without problem!!
[[BR]]
my stereo sound is acceptable using pulseaudio 0.9.15-test3 but when i
enable surround -> assertion and disaster :(
[[BR]]
also my volume controls have no meaning from 0%-60% , and after 60% the
sliders become of usage and increasing/decreasing volume level works.
[[BR]]
Below i attach logs and config for:
[[BR]]
1) default setup , config and logs for stereo output
[[BR]]
2) config and logs for surround (5,1) output.
[[BR]]
3) related alsa bugs
[[BR]]
4) alsa-time.c output
[[BR]]
5) disabling glitch-free
[[BR]]
5) a working ubuntu 8.10 PulseAudio surround setup
[[BR]]

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

If more info/testing is needed please guide me !
[[BR]]
as suggested in the logs something in the driver is buggy
[[BR]]
(alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_ca0106'.
Please report this issue to the ALSA developers.)
[[BR]]
how i should report this ? title and description that can be meaningfull
