It may sound obvious, but: did you checked that your are using the "performance" governor for cpu frequency scaling?
I found that using the "ondemand" governor can cause more xruns...
I don't know mint but there should be a cpufreq-utils package that provides relevant utilities for this.

Although my machine runs a low-latency kernel and it has been configured for pro audio (I use the realtimeConfigurationScan script), I still get xruns and sometimes qjackctl randomly hangs up making the sound to stop completely.Hey all,I just switched to Mint Olivia 15 (based on Ubuntu Raring 13.04). I use quite cpu-intensive puredata patches with processing of 2 live audio inputs on a firewire soundcard through ffado and qjackctl (jack2).
Before, I used to work with ubuntu 10.04 and rt-kernel without a itch. Is anybody still using a rt-kernel with the latest Mint or Ubuntu, or just refining settings etc..?if a rt-kernel is the best option, should I patch mine, since it looks like there are no packaged rt-kernels for Raring?
Can't access Abogani ppa, and KXS kernels are available up to Precise.thanks in advance for any hint, or suggestions about what to try!best wishes,
