Red Hat Bugzilla – Bug 314391
codec Realtek ALC 885
Last modified: 2009-06-19 21:18:06 EDT
Description of problem:
The audio(codec Realtek ALC 885) on Shiner board does not work under RHEL4.6
Snapshot2 WS. This audio codec works under R5.1.
Version-Release number of selected component (if applicable):
I'm going to assume this never worked in RHEL 4, and there therefore new
hardware enablement which requires a backport.
Support for this codec is in RHEL4, but this hardware seems to need a quirk or
special config or something. The hardware deviates from the norm somehow and
needs something special to get it working.
Please, attach output from 'cat /proc/asound/card0/codec*'.
Just want to be sure that this gets addressed and fixed in 4.7. Brian, are you
working on this? I'd assume that AMD chipset QA team can help with testing,
unless you have the necessary hardware.
If we can identify a fix thats upstream then its possible to get his in 4.7.
The hda_intel (aka AZX) driver was updated in a patch (backported from ALSA
1.0.15) that was posted for 4.6 but this has apparently not yet been included
yet in RHEL. This update may resolve the issue without any further code. I
suggest this be tested when available. For now, you may want to just verify the
issue is resolved in ALSA 1.0.15
Download 1.0.15 from here http://people.redhat.com/stransky/alsa/index.html
and confirm it resolves the issue. If its not resolved in 1.0.15 we will need
the codec info... see Comment #3, otherwise the hda_intel (AZX) update should
resolve this if 1.0.15 works OK.
ALC885 worked after updating to 1.0.15
Actually, patch in:
can fix this bug too.
Our QA has test ALC885 after using the patch, it works well.
So what's the most important is whether RHEL4.7 will accept the patch.
Committed in 70.EL . RPMS are available at http://people.redhat.com/vgoyal/rhel4/
Partners, I would like to thank you all for your participation in assuring the
quality of this RHEL 4.7 Update Release. My hat's off to you all. Thanks.
