Kernel Bug Tracker – Bug 622
ALSA Choppy During Thing Like Window Changes
Last modified: 2003-07-16 23:25:21 UTC
Hardware Environment: ALSA, 82801AA AC'97 Audio
Software Environment: Gnome
When there is a short burst of high CPU usage, ALSA tends to skip for up to a
second. This has always worked fine with 2.4.x OSS.
Steps to reproduce:
Open anything that uses OSS-emulation with ALSA. Xine and XMMS are good
examples. Switch to windows that are pretty cpu intensive in drawing, say
Mozilla. The sound chops.
Could you please add your .config? Also try building a kernel with
CONFIG_PREEMPT if you haven't already, i have personally noted that some boxes
stopped audio skipping with this enabled.
