1. How do I get jack_control to start up upon a reboot.

2. I actually got Jasper to run properly without any errors with a USB sound card with microphone and headphones plugged into it. Suddenly ALSA sound stopped working and everything went to shit from a simple typo. I had to reset ALSA setting and fix error messages by changing alsa-conf. When starting up Jasper, this is what I get:

self._stream = pa.open(**arguments)

I still am stumped on how to fix this mess.

I ran debug for Jasper and this is what it displays:
