I'm using a RME card for audio and MIDI and two Envy24 cards for MIDI. Using rtirq with it's default in /etc/rtirq.conf, resp. /etc/default/rtirq resp. /etc/sysconfig/rtirq RTIRQ_NAME_LIST="rtc snd usb i8042" caused PID CLS RTPRIO NI PRI %CPU STAT COMMAND 55 FF 90 - 130 0.0 S irq/8-rtc0 659 FF 85 - 125 0.0 S irq/20-ICE1712 671 FF 85 - 125 0.0 S irq/21-ICE1712 652 FF 83 - 123 0.1 S irq/18-hdspm switching to RTIRQ_NAME_LIST="rtc hdspm snd usb i8042" resulted in PID CLS RTPRIO NI PRI %CPU STAT COMMAND 55 FF 90 - 130 0.0 S irq/8-rtc0 619 FF 85 - 125 0.1 S irq/18-hdspm 629 FF 80 - 120 0.0 S irq/20-ICE1712 631 FF 80 - 120 0.0 S irq/21-ICE1712 Dunno, perhaps RTIRQ_NON_THREADED="rtc snd" should also be edited. Anyway, thanks to coincidence I noticed this issue and thanks to Rui I was able to correct the priority. My intend is to inform users of several PCI, PCIe MIDInterfaces to take care about priorities, when one of the devices additionally is used for audio too. I didn't test if there's an audible difference on my machine, I suspect that there isn't any difference, but IMO even this could be the cause for an issue. FWIW, I also own an USB MIDI device, a nice addition for non-rt bulk dump, for my needs useless to make music. I guess if I wouldn't use those Envy24 cards as MIDInterfaces, the RME would have first priority after the clock. - Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
