> Hey hey everyone,
> I've looked more into this problem and found that JACK will start by using
> between one and two percent of the CPU, but will gradually require more.
> After a day JACK's CPU usage stands at about 65-85%.
> Usage: currently only mpv (multimedia player, completely shut down after
> every use). No persisting audio connections, no other realtime and CPU
> hungry applications.
> JACK Version: 0.121.3
> Kernel Version: 3.9.0-rc6 SMP PREEMPT
> CPU scheduling/scaling_governor: powersave
> CPU setting: 800MHz single-core (of a 3GHz quadcore)
> Underlying soundcard device: ALSA multi with two MAudio Delta 1010 LT
> cards, sync'ed via S/PDIF.
> JACK commandline:
> jackd --timeout 4500 -R -d alsa -C cdelta -P pdelta -r 48000 -p 256 -z
> short-time load average: 0.47 (decreasing for longer periods).
> If more information or experimentation, to identify the issue, is
> necessary, please let me know.
> Thank you for any help and hints in the right direction.
