It's not worth the hype it generated. I'm just back from rolling a new kernel for 64studio. I tried a couple of candidates including -bfs. 2.6.33.7-rt29 is _by far_ the best option for low-latency audio. Well, actually it's the only option (not counting older rt-linux releases) which provides reliable <=4 ms latency (16 or 32 audio-frames per period) without any x-runs! Vanilla 2.6.36 and -bfs kernel both perform quite well. If >=15 ms latency is sufficient for your use-case and you can live with some occasional x-run that is. I'm looking forward to a new -rt patch. Cheers! robin PS. Note that sound latency here is not calculated (eg. 32*2/48kHz) but measured with jack_delay from http://www.kokkinizita.net/linuxaudio/ -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
