Re: Jack wont start

1) Don't run as root
2) You require a login manager

I need real, proper pen and paper for this.

Re: Jack wont start

If Jack doesn't work for you. maybe you should give John a try.

Cheers!

Re: Jack wont start

1) Ensure you are in audio group:

useradd -g audio alblinux

2) Ensure audio is in /etc/security/limits.conf:

@audio          -       rtprio          99
@audio          -       nice           -10
@audio          -       memlock         unlimited

You may not need to run real-time but then again, if it isn't working for you there isn't much choice. If you still fail, might as well hump John instead
