This appears to be related to pulseaudio device suspend/resume. if a device is unused for 2s, pulse will close it. if it's being used again, pulse will re-open it with the same parameters as before, which somehow fails on my usb device:
I: module-alsa-sink.c: Trying resume... E: module-alsa-sink.c: Failed to set hardware parameters: Operation not permitted See this related mail by PA's author Lennart Poettering: http://www.mail-archive.com/pulseaudio- disc...@mail.0pointer.de/msg03228.html For now i can work around this by disabling suspend-on-idle in /etc/pulse/default.pa: ### Automatically suspend sinks/sources that become idle for too long #load-module module-suspend-on-idle I regard this as what it is: just a workaround.
