Public bug reported:
Description: Ubuntu karmic (development branch)
Release: 9.10 ( Alpha 6 )
At this time not specific to any cpu and/or sound card ( 3 desktops, 1
laptop, AMD and Intel, 700 Mhz - 2.8 Ghz ),
I can recreate the problem and provide debug info per request and
further instruction.
====
note: I performed an dist upgrade on one system ( 9.04 ext3 to 9.10 ext3 )
using the update manager. This system did NOT have any problems with sound,
until I performed an Alpha 6 CD install ( 1 day ago ), formating and not
preserving user home and preferences ( fresh install with ext4 )
====
Sound in General
Audio playback ( initial alpha 6 default install and later after adding
additional codec support ), sound is muffled and crackly, think, max
volume and over amplified, even though volume settings are low-mid. So
far this applies to but not limited to: Totem-gstreamer, Totem-xine,
VLC, mplayer, Rhythmbox, Exaile, Firefox audio and video ( flash ) and
system sounds.
I am able to resolve this issue ( kind-of ) by removing the ( .pulse )
dir on boot from the user account and/or manually ( dirty workaround ).
# rc.local # mv /home/username/.pulse /home/username/.pulse-last
" mv " is not required, just a personal preference, long as .pulse is
cleared prior to login or manually, sound playback regardless of audio /
video source / codec / etc. works
Without this workaround, selecting ALSA or leaving it default has no
effect either, though I find ALSA to work best overall.
With the workaround in place, Totem-* does not have internal volume
control ( grey volume icon, mute, non-click-able ), Totem-* has been
fussy in general in Alpha 6, prior to 9.10 I've never had any problems (
8.04 - 9.04 ) in the past I found Totem-Xine to work best. With the
workaround, VLC, mplayer, Rhythmbox, Exaile, Firefox audio and video (
flash ), system sound work flawless, while totem-* does not.
The system volume control applet preferences can not be adjust with the
workaround ( error sound system is not responding ), though I can adjust
the volume / mute and I have full clear sound playback.
Firefox 3.5x and previous versions, flash has always been less than
acceptable, however, the following smooths out playback.
# about:config
# browser.sessionstore.interval;100000
On my AMD 1.3 Ghz SIS based system ( primary workstation ) I have been
receiving the following boot warnings since 9.04, though, sound worked
flawless on this machine up until Alpha 6 regardless of kernel error
AC97 codec and currently with the above workaround in place.
[ 11.437736] MC'97 1 converters and GPIO not ready (0x800f)
