Description of problem: I noticed last night that I wasn't getting any sound from my USB headset last light on a 3.6.0-0.rc3.git0.1 kernel. The device does show up properly in the sound preferences menu, but when I try to use xmms to play a song the song doesn't actually play. The progress bar stays put. I tested some other kernels (on three different machines) and found that it didn't work on 3.6.0-0.rc2.git2.1 (on any machines), but that it did work with 3.6.0-0.rc2.git0.1, PAE-3.6.0-0.rc1.git0.2 and 3.6.0-0.rc2.git1.2. Motherboard sound did work on all three machines with the 3.6.0-0.rc3.git0.1 kernel. This line from dmesg probably will give you more specific info on what the device is: [ 15.556115] hid-generic 0003:046D:0A0C.0006: input,hidraw5: USB HID v1.00 Device [Logitech Logitech USB Headset] on usb-0000:00:1d.7-6.4/input3
3.6.0-0.rc3.git1.1 also doesn't work with the headset.
OK, so if I read that correctly, the first broken version is 3.6.0-0.rc2.git2.1 and the last version that worked before that is 3.6.0-0.rc2.git1.2. Can you attach the output of alsa-info.sh? Also, can you verify with alsamixer that the headset isn't muted or turned down?
Created attachment 606941 [details] alsa-info output I didn't see any mute indicator in alsamixer. The display didn't seem to change when I muted and unmuted using the sound applet. The sound level showed 68. And showed the gain as -5 dB.
I've started a scratch build with: commit e9ba389c5ffc4dd29dfe17e00e48877302111135 Author: Takashi Iwai <tiwai> Date: Wed Aug 15 12:32:00 2012 +0200 ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream reverted (via patch -R). You'll find it here when it finishes building: http://koji.fedoraproject.org/koji/taskinfo?taskID=4421817
I tested the scratch build and headset sound is working again on the two machines that I could easily test. (The third is at work.)
There was an actual fix posted to the list which Bruno has tested. We'll roll that patch into the next update.
Patch committed to Fedora git.
I tested 3.6.0-0.rc3.git3.2.fc18.i686.PAE on two systems at home and the logitech usb headsets are working on both machines again.
