There seems to be a silly situation: lspci -v | grep IRQ -B2 output(shortened to relevant IRQs): 00:1d.2 USB Controller: Intel Corporation N10/ICH 7 Family USB UHCI Controller #3 (rev 01) Subsystem: Foxconn International, Inc.

Device d63b Flags: bus master, medium devsel, latency 64, IRQ 18 So...SATA, USB and ICE1712 share one interrupt. How can I change the interrupt of the devices, except by moving them to another slot? Though I'd really like to get rid of this, I can't imagine, this is responsible for Jack: JackGraphManager::AssertPort port_index = 4294967295 Looks like a dangling or uninitialized pointer to me. > 02:09.0 Multimedia audio controller: VIA Technologies Inc.

QJackCtl froze and I wasn't able to read the output. The command normally is: /usr/bin/jackd -P89 -v -dalsa -r48000 -p256 -n4 -m -D -Cmulti_capture -Pmulti_playback but other frames/period, Priority etc. settings don't help.

Oh yes, I found the shared IRQs and I know for certain, it's possible to use jack 1.9.7 with .asoundrc and two ICE1712.
