I've recently upgraded my kernel from 3.8.5 to 3.9.2 and ran into an issue with usb-audio: With two different usb-headsets, pulseaudio is now regularily losing the microphone audio stream (which just gets 'stuck', i.e. the level indicator bar in pavucontrol doesn't move anymore, but is not at 0).
Every time this happens I get kernel messages like these: May 25 11:05:01 nukunuku kernel: [43611.510661] delay: estimated 221, actual 0 May 25 11:06:02 nukunuku kernel: [43672.086015] delay: estimated 222, actual 1 May 25 11:06:02 nukunuku kernel: [43672.102018] delay: estimated 133, actual 0 May 25 11:07:03 nukunuku kernel: [43733.814401] delay: estimated 133, actual 0 May 25 11:08:02 nukunuku kernel: [43792.636147] delay: estimated 89, actual 0 May 25 11:10:03 nukunuku kernel: [43913.539550] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539610] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539622] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539630] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539637] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539643] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539658] cannot submit urb (err = -18) May 25 11:10:03 nukunuku kernel: [43913.539664] cannot submit urb (err = -18) Now, replugging the headset fixes the issue temporarily until it happens again, but that's a bit annoying if you're in a video call... 00:10.0 USB controller: Advanced Micro Devices, Inc.
