Comment 132 for bug 345627

Dave,

You won't see any improvement until you enable glitch-free audio (providing that glitch-free works for your hardware) - see the recent posts by myself and Daniel. Until this is done officially, you can edit the configuration files yourself:

1. Create a copy of the configuration files to your user's pulse folder:
$ cp /etc/pulse/* ~/.pulse/

2. Edit ~/.pulse/default.pa, do a search for "tsched=0" and change to "tsched=1".

3. (Optional). Edit ~/.pulse/daemon.conf and comment the "resample-method", "default-fragments" and "default-fragments-msec" lines, like so:

; resample-method = speex-float-1
; default-fragments = 8
; default-fragment-size-msec = 10

This should completely eliminate stuttering, as long as your audio card doesn't trigger certain kernel bugs (see my previous comment to see a related bug).

Note: be sure to delete the contents of ~/.pulse/ to revert these settings if there is a pulseaudio update, otherwise the newer configuration files in /etc/pulse will get ignored.
