Description of problem:
Chromium runs fine as far as gameplay and graphics go when I use either the
OSS/Free drivers that come with RH7.3 or the ALSA0.90rc1 drivers. Bu the sound
does not work fine with ALSA0.90rc1.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install the ALSA 0.90rc1 drivers
2. Run Chromium
Actual Results: Sound pops and doesn't work well.
Expected Results: Sound should work properly.
The reason that that I am using the ALSA0.90rc1 drivers at all is that the
OSS/Free drivers do not seem to properly support full duplex or even recording
at all on my laptop's i810+ac97 sound setup. The ALSA drivers seem to work for
me in gnomemeeting, xmms, MPlayer, and even Tux Racer. Chromium seems to be the
only problem. This suggests that the bug is in Chromium and not in ALSA.
A workaround that seems to work is to make sure that no sound apps are running
and then unloading ALSA kernel modules and switching /etc/modules.conf to use
OSS/Free instead. Upon finishing the game of chromium, one can switch back the
same way to run ALSA again.
The sound hardware is an IBM X22 Thinkpad with an ICH3 soundchip with Cirrus
Logic CS4299 rev 6 ac97 codec.
To help debug this, I installed the ALSA drivers on one of my Dell P3 desktops
that has a Creative Soundblaster 16PCI sound card (es1371 drivers in OSS and
snd-ens1371 in ALSA). There are no skips or pops with either the OSS or ALSA
drivers in that case.
So I suspect that the problem here is some more subtle thing having to do with
the combination of chromium, ALSA0.9rc1, and the laptop's hardware.
if you want to have alsa support in chromium you have to rebuild
chromium with -enable-alsa.
Red Hat does not support ALSA sound.
