Hi all,

I'm wondering if anyone else has run into audio problems since upgrading
to maverick on an Asus UL30A. Ever since the upgrade I've had constant
sound dropouts and glitches. I've tried the following steps to fix the
problem, but with no luck so far:

- Drop down the default overclocking setting from 3% to 0%
- Install both the 2.6.36 and 2.6.37rc1 kernels from the mainline ppa
- Install the packages from the ubuntu-audio-dev ppas
- Disabling pulseaudio's glitch free mode using tsched=0 (seemed to make
the problem more extreme)

Other things I've noticed:
- The problem seems a lot worse when running on battery power
- Pulseaudio logs a lot of "pulseaudio[1700]: ratelimit.c: 129 events
suppressed" messages to the user.log


Has anyone else encountered this? Does anyone have any debugging steps I
could try to track down this issue?

Kind regards,
Nyall Dawson
