View Full Version : [ubuntu] PreSonus FP10 recording help

February 1st, 2010, 02:15 AM
I installed Ubuntu on my friends Desktop computer today and he loves it. Although there is only one problem, it can't recored using his PreSonus FP10 FireWire Recording System. I installed Ardour on his Ubuntu desktop and it uses Jack to connect to the FP10. When I get Jack running it will stop right after I start it and it exits with this error.

I was able to get Jack to run using this command in terminal

sudo jackd -R -d freebob

When I run that command the FireWire indication light on the FP10 turns changes from red to blue, which indicates that it detects the computer. Then after that I run Ardour and it starts up correctly but when he tries to record, no sound is recorded. I checked to see if the freebob driver is installed and it is installed. Does anyone know how to properly use the PreSonus FP10 with Ardour?

Any advice would be appreciated.

There's the problem. For a simple workaround, un-check the realtime option in Jack Control. For a better and more permanent solution, follow this guide:
Good luck! If you have more problems or questions, please post back.

When you ran jack as root (with sudo) then it connected to the firepod because root has permissions for everything. But then there are other problems as you found out. So follow the guide and fix it right.
