Public bug reported: At first, I raised this issue: https://bugs.launchpad.net/ubuntu/+source /alsa-driver/+bug/1186621 this is the main symptom of my problem.
Then, after some searching around, I came across this http://askubuntu.com/a/3078/13879 which sounds like a reasonable cause to my current problem. I'm not sure if it is a genuine bug, or just some configuration issue, as I was following a few guides to get some jack stuff working, and edited a few config files etc. ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: linux-image-3.8.0-25-generic 3.8.0-25.37 ProcVersionSignature: Ubuntu 3.8.0-25.37-generic 3.8.13 Uname: Linux 3.8.0-25-generic x86_64 NonfreeKernelModules: fglrx ApportVersion: 2.9.2-0ubuntu8.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: david 2313 F.... pulseaudio /dev/snd/controlC0: david 2313 F.... pulseaudio /dev/snd/pcmC0D0p: david 2313 F...m pulseaudio CRDA: Error: command ['iw', 'reg', 'get'] failed with exit code 1: nl80211 not found.
