Title:
Sound interruptions during high radeon OpenGL load
Status in linux package in Ubuntu:
Confirmed
Bug description:
On my Dell Inspiron 6400 laptop with Mobility Radeon X1400 and built
in Intel HDA audio with STAC9200 codec, audio is normally perfect.
Even with 100% load on both CPU cores audio is perfect. However, while
playing high resolution video, audio has many tiny regular
interruptions which can be like crackles or micro stuttering. This
happens when playing 1080p YouTube video in Chrome or 1080p video via
VLC using the OpenGL output. Other high GPU load, like scrolling
Google Maps around a lot in Chrome, can also cause these
interruptions. They don't only affect the application causing
graphical load, but also affect other applications playing audio, like
mpg123.
I've changed bdl_pos_adj, position_fix and enable_msi parameters of
the snd_hda_intel module. Maybe bdl_pos_adj=64 and position_fix=1
makes it a bit better, but I'm not certain and it's certainly still
not okay. I tried interrupt priorities as described in
https://wiki.ubuntu.com/UbuntuStudio/rtirq and that didn't help.
Changing latency via setpci seems not applicable because this laptop
uses PCI Express. Not running PulseAudio and using ALSA instead
doesn't help. Running a bare-bones X configuration with twm doesn't
help.
Configuring VLC to use XVideo video output makes audio perfect with
the same video which was causing these interruptions when using OpenGL
video output.
