I have exactly this tab already opened. It crashes without clients. Will now try jack1, if it doesn't help change slots until I have IRQs fixed. My BIOS allows to reserve IRQs I just don't understand how that's supposed to work: I can choose either "PCI" or "reserved" per IRQ-number. So...what's happening if I reserve let's say #15 ? Anyway I'd have to check out which device is hw:0 and hw:1 again etc. That's why I'll test jack1 first. /mn0 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
