Hi, I have a VXpocket v2 running under a 2.6.5-gentoo-r1 kernel which is patched with rt caps. I find that with jackstart, I can get away with 2 periods of 512 samples if the communication is 1-way, but in duplex mode I need 2 periods of 4096 samples to avoid xruns. Surprisingly, my on-board soundcard has better performance! Is this much different under a low-latency 2.4 kernel? Would it be better if the card were hw:0 instead of hw:2? Also, is it normal for the card to distort if the PCM level is above 82? I wasn't having this distortion problem with W2K if IIRC. Cheers, Chris
