[sudo-discuss] firewire audio for linux

[robb]

despite the hubblub out there about firewire audio not being supported by
linux, all i had to do was:
*sudo gedit /etc/default/rtirq*

change

RTIRQ_NAME_LIST="rtc snd usb i8042"
to
RTIRQ_NAME_LIST="rtc *firewire* snd usb i8042"

&

RTIRQ_NONE_THREADED="rtc snd"
to
RTIRQ_NON_THREADED="rtc *firewire* snd"

open *qjackctl* -> click Setup -> change settings to

Driver: *firewire* (This selects the ffado driver stack)
Interface: hw:0

Audio:Duplex (or Capture only)
Check Realtime
Priority: (default)
Frames/Period: *128*
Sample Rate: 44100 (adjust the sample rate to the specs of your fw device)
Periods/Buffer: 3
