Red Hat Bugzilla – Bug 682480
SPDIF out not working with kernel > 18.104.22.168-48 (Intel HDA / ALC889)

External amp shows signal, but there is no sound.
F13 with latest kernel and F14 with 22.214.171.124-48 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 126.96.36.199 but not in 188.8.131.52-48 (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
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?
a simple revert would break it for other people, see bug 657388
adding kyle to cc, maybe he has an idea
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 ;)
fix is in 18.104.22.168
22.214.171.124-88.fc14 is available in updates-testing
