Description Rumi 2012-09-28 21:34:36 UTC
Description of problem:

Since upgrading to kernel 3.5.4-1, no sound gets played, from any source I tried. All sound settings appear to be correct. When I boot into 3.5.3-1, the sound is present as expected. There is no visible change in sound settings after the boot into the other kernel. 

Version-Release number of selected component (if applicable): Kernel 3.5.4-1


How reproducible: The bug appears after each boot with this kernel version. It does not appear after boot with an older version. 


Steps to Reproduce:
1. Select kernel 3.5.4-1 from the GRUB screen when booting
2. Copy a known-good wav file called mytestfile.wav to the current directory
3. aplay -vv mytestfile.wav
(can also be reproduced with sound from any other source, using any playback software, or with the command  speaker-test -c 2 -t wav)
  
Actual results:

There is no sound audible 
There are no error messages of any kind 
The output of aplay is as expected for this type of file, listing format, bitrate, etc. 

Expected results:
There is sound audible 
There are no error messages

Additional info:

The sound card is model Onkyo Wavio SE-U55SX.

The system is a custom-built desktop setup, based on a i7 930 CPU. 

The settings visible in Phonon, alsamixer and pavucontrol appear correct: nothing is muted, the correct playback device is selected, etc. 

The sound card's model is correctly recognized in /proc/sound/cards. 

The output of sudo lsmod | grep snd is: 
snd_usb_audio         134325  2 
snd_usbmidi_lib        24728  1 snd_usb_audio

Another user seems to have the same problem with a different sound card model, again USB-based, see http://ask.fedoraproject.org/question/2558/no-sound-after-update-to-kernel-354-1-fedora-17?comment=4581#comment-4581.

Comment 1 Rumi 2012-10-01 15:38:48 UTC
The bug seems to have been submitted in parallel to the Kernel bug tracker by another user, https://bugzilla.kernel.org/show_bug.cgi?id=48051. There seems to be a patch for it, https://lkml.org/lkml/2012/9/27/172, not yet included in any kernel version. Not sure if I should close this one (or if it is indeed the same bug).

According to the upstream bug, this was fixed in 3.6.
