synchronization issue at the beginning
this is still not resolved and its a pain in the ass to get this done
The funny thing is, after I reverted to the 10.0.16 release tarball these stuttering problems went away. So the fixes that were committed in february/march under the 'fixes realtime behaviour' label actually made things much worse..
without SND_CARD_LOOPBACK_START_SYNC, its still the same. you should really get a tickless kernel first. otherwise its just pure luck and frustration.
try to find the right place and resubmit. :)
(in my own spare time). Can you give me any pointers perhaps? They would be
usually snd_card_loopback_playback_trigger gets called with SNDRV_PCM_TRIGGER_STOP whenever the device is about to be closed. so the next function would be snd_card_loopback_close. try snd_card_loopback_timer_stop there and report :D
