fglrx and ie1394. On my DAW I use neither. > system on this laptop? I have the fancy sound card (RME 9652 which is in a word simply awesome) in a desktop machine. My laptop does some editing and mixing after the fact and it is pretty stable but it does not have a very good audio device. The latency is workable with a MIDI keyboard. I would disable CPUfreq while doing audio work. Since you already have the Presonus I guess replacing it is not an option (I have yet to have success with FFADO/FreeBob). Disable network manager. Keep an eye on running services (htop/atop are good for this). Disable things that you don't need, such as apache and mysql (if you have them running). If possible do not use fglrx. I know it is pretty but what is more important? For my DAW I use the plain 2d only ati driver. > Is it even possible? > Should I switch back to Windows until Presonus help out the FFADO people?

Reminds me of Cubase SX and Win2k/XP. This experience is what drove me to a FLOSS solution.
