note that I used -q 1 as an option to alsa_in/out. This has to do with the resampling quality. At 2.3ms latency, 96kHz s.r. on a 2 x 2.4 GHz dual core CPU system and using Jack2, I get a low CPU usage (1-2%) and the quality is reasonable. If you push it to 2, 3 or 4, the CPU will increase quite a lot at small buffering / latency
what would be 100% quality? -q 1 I get obvious distorcion. -q 2 I can't here any diference
like I said, I still have a problem with java-sound. I have to close all alsa-apps before running REW, to here an output and I can't manage to get a signal on input
that's great news but I can't use it with the crappy snd-hda-intel card I got... the only kernel and can run audio is the RT on my laptop but my old pc, kernels 2.6.36 and 37 working amazingly with jack but it's not that powerful for my needs..
