It's an upstream bug. I usually use /etc/conf.d/rtirq.good¹ and with this config it works for Ubuntu Studio too. For testing purpose I now booted Arch with the default config and it fails in the same way, as it fails for Ubuntu Studio.
It's not an issue for a customized audio install, but a serious issue for an audio install that is used with the OOTB defaults. ¹ [rocketmouse@archlinux ~]$ grep IRQ_NA /etc/conf.d/rtirq* | grep -v '#' /etc/conf.d/rtirq:RTIRQ_NAME_LIST="snd usb i8042" /etc/conf.d/rtirq.good:RTIRQ_NAME_LIST="snd_hdsp snd_ice1" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1482347 Title: [rtirq-init] Broken RTPRIO order To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1482347/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
