Description of problem: SPDIF output for AD1988b chipset doesn't work correctly with non-AC3 content. The sound is played, but it has distortions. There's already a patch in alsa-kernel to fix this problem: http://hg-mirror.alsa-project.org/alsa-kernel/rev/43059389c583 http://mailman.alsa-project.org/pipermail/alsa-devel/2007-July/002213.html Version-Release number of selected component (if applicable): How reproducible: A motherboard with AD1988b sound chipset is needed, for example Asus P5B-E Steps to Reproduce: 1. aplay -D spdif some.wav Actual results: The wav file is played, but the sound has distortions. If the wav is played through non-SPDIF connection everything is ok. Expected results: The wav file would be played similarly through both SPDIF and non-SPDIF connection without any distorsions. Additional info:
kernel-2.6.22.5-76.fc7 is in the updates-testing repository with a fix for this bug.
This bug re-occurred with kernel-2.6.23.1-21.fc7 using alsa-lib 1.0.14-3.fc7. I also tried with alsa-lib 1.0.15-1.fc9, but it doesn't work either. kernel-2.6.22.9-91.fc7 works ok.
Patch was dropped during update to 2.6.23. Re-added.
Hello, I'm reviewing this bug as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage Given that the patch was confirmed working before and has been re-added with no additional comment from the reporter I am closing this CURRENTRELEASE. Please do not hesitate to re-open if it is still an issue for you. Thank you for filing the bug.
