but one problem i came over is the following:
I made the audio thread shced_fifo with max priority. My GUI thread is
sched_other. To allow the GUI to rerspond, I thought i could just put the
audio thread to sleep for the playing length of the buffer (7ms).
There's something fundamentally wrong here. Normally, the audio thread
synchronises with the audio (ALSA) driver. It will be waiting most of the
time, giving other threads a chance to run, and the problem you describe
then does not exist. This is really the first thing you should get right.
