Hi all, I just wanted to give you an update on my quest for super-low-latency. I bit the bullet and compiled a rt-kernel. And the result is super-stable audio with a period of 32 samples @48Khz (for a total roundtrip latency of 3.5ms). With a (peak) cpu load hovering around 70% on all 4 cores I don’t get any xruns anymore. (even when running a bloated desktop that comes with mint :-)
I only tested it running for a few minutes, we’ll see what happens when running for a few hours, but I’m happy so far. My conclusion is that the lowlatency kernel is nice for lowish latency with a load that isn’t too high, but it just doesn’t cut it for high demanding work. I want to thank you all for your input, I have learned a lot. cheers, Fokke > IOW for detailed help the output of commands might be needed, depending > to what is unclear the it could be the output of lsusb, > cat /proc/interrupts, rtirq status, cat /proc/asound/cards, > tree /sys/bus/usb/drivers/usb/ etc.. > _______________________________________________ > Linux-audio-dev mailing list > Linux-audio-dev@lists.linuxaudio.org > http://lists.linuxaudio.org/listinfo/linux-audio-dev _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
