Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed- groovy to verification-done-groovy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification- failed-groovy. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B.

When running "pactl load-module module-detect" the sound card shows up, and playback works as expected. If pulseaudio is restarted with "pulseaudio -k" the playback device disappears again. Running the above command get things working again. If I change the following section in /etc/pulse/default.pa from: ### Automatically load driver modules depending on the hardware available .ifexists module-udev-detect.so load-module module-udev-detect .else ### Use the static hardware detection module (for systems that lack udev support) load-module module-detect .endif To: ### Automatically load driver modules depending on the hardware available #.ifexists module-udev-detect.so #load-module module-udev-detect #.else ### Use the static hardware detection module (for systems that lack udev support) load-module module-detect #.endif Things start working as they should after running "pulseaudio -k".
