Hi list, jackd1 on my computer strangely suddenly uses 100% cpu and I find the following ALSA: seq_lock: waiting [1 left] in sound/core/seq/seq_ports.c:266 in dmesg. I can not quit it with qjackctl and had to do a hard power reset, despite jackd1 being still able to receive and output audio signals. Is this error known in any way? I can't seem to reproduce this behavior. Thanks! P
