Red Hat Bugzilla – Bug 64779
multi-tasking is not working smoothly with sound
Last modified: 2005-10-31 17:00:50 EST
Description of Problem:
When I do task such as read a cdrom with listening to thelinuxshow.com via the
web ... the sound is chopped to threads. It seems to be the mult-tasking of the
new kernel ...
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install 7.3 out of the box
This is likely do to the new default of disabling dma on cdrom drives. This
causes cdrom access to cause insane latency. You can probably found the bug
report I made about this problem if you look into bugzilla. It was marked
NOTABUG. I recommend commenting out the offending lines in /etc/rc.d/rc.sysinit.
Redhat recommends you set dma to 1 using sysctl.
it's easy to check this temporary by typing
hdparm -d 1 /dev/hdc
(assuming hdc is your cdrom)
Does that fix it ?
