Set ther cpu-governor to performance (so it
doesn't switch frequencies which
produces xruns) but reduce the maximum allowed frequency.
what kernel are you running?
I do have realtime-kernels (2.6.31.12-rt21, 2.6.33.7-rt29) running on 4
PCs/Laptops (Intel core duo 32bit, Intel Core 2 Duo 64bit, Atom and an
Intel-i5) and on none of them frequency-scaling ever caused any x-runs.
The ondemand governor is ruling them all.
It /might/ be an issue with other CPUs or mainboards.. or non-RT
systems, or with extreme low latency. But I'm not seeing any issues with
freq scaling even at 32*2@48kHz.
