Red Hat Bugzilla – Bug 496624
[VirtualBox] snd_intel8x0 audio choppy
Last modified: 2009-08-04 08:16:37 EDT
Description of problem:
I previously uninstalled PulseAudio because of a different bug, so I'm using ALSA directly. Sound is continuously choppy and/or repetitive on recent rawhide kernels when running inside VirtualBox 2.2.0 OSE on Mac OS X (using the snd_intel8x0 driver).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. mplayer $FOO
2.6.29-0.159.rc6.git3.fc11.i586 works. I'll try and do some bisecting.
My bisection reveals that this problem was introduced in this exact version: 220.127.116.11-70.fc11.i386. cc'ing wwoods since it was his patches.
This bug appears to have been reported against 'rawhide' during the Fedora 11 development cycle.
Changing version to '11'.
More information and reason for this action is here:
rmmod snd-intel8x0 and then modprobe snd-intel8x0 ac97_clock=41194 does not solve this issue (the parameter was suggested in another bug report).
I am unable to reproduce this in Rawhide with in VirtualBox-OSE from RPM Fusion.
Assuming the pcm positioning fix that went into 2.6.31 (see bug #506075) fixed that, closing. (please reopen if you manage to reproduce this).
