The possible solution is to replace the following 3 lines in
/etc/pulse/daemon.conf:
; default-sample-format = s16le
; default-sample-rate = 44100
; default-sample-channels = 2
With:
default-sample-format = s16le
default-sample-rate = 48000
default-sample-channels = 2
Either, it works for me yet. And after several reboots too.
** Changed in: linux (Ubuntu)
Status: New => In Progress
** Description changed:
Every playing sound have a buzz (crackle) while playing. You can see
alsa-output from another bug:
https://bugs.launchpad.net/bugs/296011
Here is the link to the alsa-info.sh generated output (from thouse bug):
http://www.alsa-project.org/db/?f=92d2b0197f25c747eb59842a0f2678a92dd6d160
There are the same kernel, same sound card (snd_hda_intel module), all the
same (without any updates).
1) So after computer start up, i had sound crackling. Then i make
'alsa-info.sh' generated output. After that, i've edited
/etc/modprobe.d/blacklist , commented last line:
# low-quality, just noise when being used for sound playback, causes
# hangs at desktop session start (Ubuntu: #246969)
# blacklist snd_pcsp
2) Then i reboot system, and the sound was without any crackling.
- 3) Another reboot return back into the same situation. So i uncommented (see
1) ) de nouveau blacklist module snd_pcsp.
+ 3) Another reboot return back into the same situation. So i uncommented (see
1) ) again blacklist module snd_pcsp.
4) After reboot, there is the same crackling as in 1,3 cases.
All 'alsa-info.sh' output are similar except the order of the loaded
- modules. May be this is a cause. File 'all' contain olny order of the
+ modules. May be this is the cause? File 'all' contain olny order of the
sound modules for all cases.
