Re: Jack Problem
The only suggestions I have are to see https://support.hifiberry.com/hc/en-us/ ... 0342-Jackd and the JACK-on-Pi section of https://wiki.linuxaudio.org/wiki/raspbe ... nning_jack.
Re: Jack Problem
i just got jack working, it turns out there are 2 common 'audio servers' for linux distributions
- pulse audio
- jack
they can apparently co-exist.
both of them feed into alsa as the underlying 'driver' layer.
if sound is working for other apps, look in /etc/asound.conf, there may be an entry like such
then in qjackctl when specifying the driver parameters, it needs to be
hw:2,5
there is also a different problem about ulimits that needs to be fixed for jack to work
