on my x86-64, there doesn't seem to be an irq for snd-intel8x0.
optie ~ # cat /proc/interrupts CPU0 0: 1406459 IO-APIC-edge timer 8: 0 IO-APIC-edge rtc 9: 0 IO-APIC-level acpi 14: 33574 IO-APIC-edge ide0 15: 21 IO-APIC-edge ide1 177: 624454 IO-APIC-level eth0 185: 286001 IO-APIC-level libata, ehci_hcd, ohci_hcd, ohci_hcd 193: 37964 IO-APIC-level AMD AMD8111 NMI: 0 LOC: 1406207 ERR: 0 MIS: 0
ps ax doesn't seem to show anything sound-related except jackd so I tried chrt -f 75 jackd -R -d alsa -P -HMm -z s -o 6
result during an emerge metadata on V0.7.13:
**** alsa_pcm: xrun of at least 133.973 msecs **** alsa_pcm: xrun of at least 78.544 msecs **** alsa_pcm: xrun of at least 245.494 msecs
*much* better but we're shooting for 0 xruns, no?
