Now tried several alsa-lib versions. A clue would be nice? What do I replace to fix this ?
Now tried 2 kernels, 3 versions of alsalib still stalls.
The synchronization calls in alsa-lib shouldn't block unless you're actually using several threads, and even then you wouldn't be able to reproduce it so reliably.
Do you have a stack trace to find out where this is called from?
Can you confirm that pthread mutexes work on your board?
