Hi, I have the same problem, both in 9.10 and 10.04, and both after fresh installs. When I play mp3 files or video in banshee, rhythmbox, mplayer, or vlc the sound skips/stutters randomly during the song (every 20 seconds to 1 minute). I installed the following codecs and programs after the 10.04 install:
sudo apt-get install ubuntu restricted extras sudo /usr/share/doc/libdvdread4/install-css.sh sudo apt-get install mplayer smplayer sudo apt-get install vlc vlc-plugin-pulse When I remove pulseaudio using system76's code (below) the stuttering stops in both audio and video. touch ~/.pulse-a11y-nostart echo autospawn = no|tee -a ~/.pulse/client.conf killall pulseaudio When I enable pulseaudio (below) the stuttering begins again. rm ~/.pulse-a11y-nostart rm ~/.pulse/client.conf I started this thread http://ubuntuforums.org/showthread.php?t=1471262 to see if anybody had some answers. Based on that I have tried the following to no avail: 1) Tweaked the default-fragments and default-fragment-size-msec default values in the file /etc/pulse/daemon.conf 2) sudo dpkg-reconfigure pulseaudio 3) Changed realtime priority from 5 to 8 in /etc/pulse/daemon.conf 4) Added tsched=0 to load-module module-hal-detect in system.pa I am attaching a bit of the user log when I watch video with pulse and it stutters. It seems I get a lot of the following statements: May 19 14:11:38 coldwater-laptop pulseaudio[1478]: ratelimit.c: 5 events suppressed May 19 14:40:07 coldwater-laptop pulseaudio[1424]: pid.c: Daemon already running. May 19 14:45:32 coldwater-laptop pulseaudio[1402]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! May 19 14:45:32 coldwater-laptop pulseaudio[1402]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. May 19 14:45:32 coldwater-laptop pulseaudio[1402]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail. May 19 14:46:04 coldwater-laptop pulseaudio[1402]: ratelimit.c: 8 events suppressed May 19 14:46:30 coldwater-laptop pulseaudio[1402]: ratelimit.c: 1112 events suppressed May 19 14:48:33 coldwater-laptop pulseaudio[1402]: ratelimit.c: 1300 events suppressed I have been posting on your forum these last few weeks about this issue. It appears that a significant number of us are having problems with pulse and that there is no ready solution. Is there either a way to fix this bug and continue using pulse or to disable pulse and do the following. 1) Fully disable pulse and install whatever replacement alsa packages are required 2) Setup up alsa so that one can change the volume controls with the fn F7,F8 3) Install an alsa applet for the top panel so one can switch inputs, outputs etc, 4) Change the loudness or gain. When under pulse I could keep the volume around 2/3 and it was plenty loud. Under alsa, it is up all the way and it is not loud enough.
