Description Aurelien Bompard 2013-03-06 08:10:58 UTC

Description of problem:
The SPDIF output to my Dolby Digital (AC3) receiver stopped working with the update to kernel-PAE-3.8.1-201.fc18.i686. It worked fine on kernel-PAE-3.7.9-205.fc18.i686

I'm testing it with an AC3 video and mplayer -ao alsa -ac hwac3. Just rebooting ans switching the kernel solves it.

When I look at the optical cable, there isn't any light coming out with the latest kernel, while there is a seemingly constant red light with the one before.

Version-Release number of selected component (if applicable):
kernel-PAE-3.8.1-201.fc18.i686

How reproducible:
Always

Comment 1 Marcin Garski 2013-03-10 19:37:20 UTC

Same here on x86_64 with snd_hda_codec_realtek and snd_hda_intel. Audio works on analog output.

Comment 2 Aurelien Bompard 2013-03-17 06:37:10 UTC

SPDIF output still does not work with kernel-PAE-3.8.2-206.fc18.i686

This may be useful:

Comment 4 Alessandro 2013-03-24 20:40:35 UTC

This bug i marked i686 but the very same happens on x86_64 platform

Comment 5 Alessandro 2013-03-24 20:42:14 UTC

I reverted to 3.7.9 to have sound back (sorry for double posting I've hit submit too early)

Comment 6 Josh Boyer 2013-04-16 19:32:13 UTC

Is this working with 3.8.7 now?

Comment 7 Aurelien Bompard 2013-04-16 22:41:10 UTC

No, still no light out of my optical cable.
kernel-PAE-3.8.7-201.fc18.i686.PAE

Comment 8 Alessandro 2013-05-04 19:04:10 UTC

kernel-3.8.11-200.fc18.x86_64 doesn't work either

I stick with 3.7.9

Comment 9 Marcin Garski 2013-05-27 18:09:54 UTC

Still valid for 3.9.4-200.fc18.x86_64.

Can I provide you some information that can help you track what cause the problem?
