Description of problem: After upgrading from F17 to F18 via yum, there is no longer any sound coming in from the PCM2904 soundcard of a Project RIAA amplifier I have. Version-Release number of selected component (if applicable): pulseaudio-libs-2.1-6.fc18.x86_64 kernel: 3.9.4-200.fc18.x86_64 How reproducible: 100% Steps to Reproduce: 1. Upgrade from F17 to F18 (not sure if via yum is a culprit or not) 2. Put a record on your turntable with your Project RIAA preamp 3. Try and play the record via module-loopback or record via audacity Actual results: -No sound via module-loopback. -Audacity doesn't record anything, just loops forever without ever leaving time 00:00:00, it just flickers at the beginning of recording. -Sound Settings from the icon up top right opens a windows but crashes in a fraction of a second. Expected results: Sweet music via module-loopback. -Audacity records the music being played. -Sound Settings doesn't crash. Additional info: I've done lots of 'pactl load-module module-loopback' to no avail. All worked fine before the upgrade.
After a reboot, sound came back, but then disappeared again. This was in dmesg: [426922.203490] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203500] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203506] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203512] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203518] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203523] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203529] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) [426922.203535] ALSA sound/usb/endpoint.c:391 cannot submit urb (err = -18) After this a pulling out the USB cable and reinserting it got the sound back again.
This is related to #975158 Sound disappeared again. And this time unplugging and replugging didn't help. Tried 5 times. And loaded module loop-back 7 times. By viewing 'pactl list | less' I could see that I know had two copies of the same soundcard as source #9 and #10. A workaround: 'pactl load-module module-loopback source=10' where 10 is the second now working soundcard. I could see that the soundcard was recording ok, but loopback's automatic configuration doesn't work after the soundcard has messed up. Really annoying regression.
All the ALSA references here, sounds like this is much more related to that than anything pulseaudio related, reassigning. May be worth posting the outout from $ alsa-info
I encountered this issue after removing the Nvidia drivers and using the standard nouveau drivers. My USB DAC never had any problems prior. Sound will play but will bomb out randomly. dmesg: https://gist.github.com/jdoss/6054656 alsa-info: http://www.alsa-project.org/db/?f=d797e7bfc026dc51159754a8a32ab2172f37473d
It looks like an issue in the kernel USB core code (iso stream scheduler).
To be clear, this impacts F19 too using the current kernel installed by yum, 3.9.9-302.fc19.x86_64. I was trying different kernels trying to see if I had any changes in behavior so it does the same thing all the way up to 3.11.0-0.rc1.git4.1.fc20.x86_64, so my last gist URL reflects that kernel version. Here is the dmesg for 3.9.9-302.fc19.x86_64 on F19: https://gist.github.com/jdoss/6062790 just in case it is needed. Oddly enough if you install the kmod-nvidia-3.9.9-302.fc19.x86_64.x86_64 drivers from RPM fusion the issue goes away... I doubt that is of much concern to you guys due to the nature of these drivers but I thought it was worth mentioning.
This bug was actually about the bug in pulseaudio that is triggered by the bug in the kernel. There is a bug in the kernel, yes, #975158, but there is also a bug in pulseaudio so I had 2 soundcards and 'pactl load-module module-loopback' doesn't work.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 18 kernel bugs. Fedora 18 has now been rebased to 3.11.4-101.fc18. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 19, and are still experiencing this issue, please change the version to Fedora 19. If you experience different issues, please open a new bug report for those.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale.
