Can't export song files in Hydrogen drum program

Well; I'm having audio problems again,
so today I added my user into the audio group with:

su

usermod -a -G audio wordstrings

which eliminates the "permission denied issue"
Then went:

[wordstrings@DTR-Arch-Linux ~]$ hydrogen

and then the audio wouldn't work in Hydrogen...

Now; the previous time I opened Hydrogen, the audio did work, but I made a quick drum track and tried to export it and in the process of doing so, (made it to where the audio stopped working?)
How can I get audio back and export song files?
Thanks in advance for any tips!

Re: Can't export song files in Hydrogen drum program

Are you starting jackd in realtime mode? If not, maybe that's what causes Hydrogen zombification. You could try to start jack manually beforehand, for example via qjackctl.

I can offer what works for me, maybe you want to try to replicate my setup.

I'm using hydrogen 0.9.5.1-4 and jack2 1.9.9.5-4. I start jackd via qjackctl 0.3.11-1 with the following setup:

Generated command line:

/usr/bin/jackd -P80 -p128 -t4000 -dalsa -dhw:0 -r48000 -p256 -n2 -Xseq

I'm not using a realtime kernel, just stock Arch Linux, right now linux 3.12.7-1 (haven't updated yet to 3.12.7-2).

Aside from all that, you can get great help for Linux audio issues at linuxmusicians.com, lots of knowledgable folks there.
