Jackd crash

Post by escuta » Sat Apr 07, 2018 11:52 pm

Hello,

Doing tests overnight and over a number of hours, I'm getting periodic jackd crashes and an accompanying very nasty noise through the headphones. I'm using the following to launch jackd:

/usr/bin/jackd -P75 -dalsa -dhw:0 -r44100 -p1024 -n3 -P&

I don't want to increase the latency any more than it already is. Can something be done to make jack more stable?

This crash does not happen when I use the Pi internal audio. I'm using Raspbian Stretch and running code in SuperCollider.

I'll paste below some of the print out from the last crash.

Thanks

Is jackd running with real time priority ? Is it bumped up to the maximum ?
