Good questions :) Sound card is one VIA 8233. Ok, it's a very bad and ugly soundcard, but is just for test. In next week that machine will have one SB Audigy Platinium. I start jack with: jackd -v -R -d alsa -d hw:0 -r 44100 -p 2048 But I tried othes options and continue with xruns. I think my hdparm can't get this DMA information. I'm getting the source code of hdparm to find some option in compilation. Your suggestion send to me: /dev/dsp not supported by hdparm Thanks again!
