Description Ronny Buchmann 2011-03-05 18:12:41 EST
External amp shows signal, but there is no sound.

F13 with latest kernel and F14 with 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 but not in (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 19:54:03 EDT
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 17:16:24 EDT
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 19:49:12 EDT
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 ;)
