Description Ronny Buchmann 2011-03-05 23:12:41 UTC 
External amp shows signal, but there is no sound.

F13 with latest kernel and F14 with 2.6.35.6-48 is working.

It looks like the problem is caused by the fix in #657388 respectivly commit bc23f2c11af8b5d32724fe3e226e3edb0fdf6fb2 (this seems to be the only change which could affect ALC 889).

Analog output is working in 2.6.35.11 but not in 2.6.35.6-48 (it's working in F13 with 2.6.34.x). So I can confirm that #657388 is fixed (for analog output).

problem still exists with kernel-2.6.38-1.fc15.x86_64
Comment 7 Szymon Stasik 2011-03-21 23:54:03 UTC 
since there is a patch in https://bugzilla.kernel.org/show_bug.cgi?id=24342#c13 and seems to work fine - what are next steps to revert this in fedora kernel packages?
Comment 8 Ronny Buchmann 2011-03-22 21:16:24 UTC 
a simple revert would break it for other people, see bug 657388

adding kyle to cc, maybe he has an idea
Comment 9 Szymon Stasik 2011-03-22 23:49:12 UTC 
I can confirm that https://bugzilla.kernel.org/show_bug.cgi?id=24342#c13 solves my problem at least so I guess it will work for most of other people on CC here and there ;)
Comment 10 Ronny Buchmann 2011-04-01 06:46:41 UTC
