[linux-audio-dev] hdsp+latency questions

hello everyone! this is not exactly about audio-development, but the DRI+jack thread encouraged me to ask a few questions about optimizing my setup: i'm using a rme hdsp (cardbus) + multiface with my 1ghz pIII laptop for quite a while now, and i'm happy with it. i would like to use the setup for live-processing but the lowest jackd framesize i can safely use is 2048. the main issue here seems to be the nvidia graphics card. since i switched from kernel 2.4.2x+lowlat+capabilities to 2.6.1 the cpu-load seems to be noticable higher for ardour, but the latency-issue did not change. so my questions are: *) is anybody successfully using hdsp-cardbus with really low latencies ? *) how important is the firmware version - which firmware version should i use for my hdsp card? *) did anyone else notice increasing cpu load with audio-apps + kernel 2.6.x ? *) any hints about configuring X11 for linux-audio (besides from DRI questions ;-) ? let me know if you think i'm on the wrong list should better alsa-dev. thanks in advance regards d13b -- Military intelligence is a contradiction in terms. -- Groucho Marx
