Hi All,
I'm having a very strange problem setting up Jack.
I have a card which aplay -l lists as
card 0: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

card 0: SB [HDA ATI SB], device 1: ALC892 Digital [ALC892 Digital]

  Subdevices: 1/1

  Subdevice #0: subdevice #0
I'm only interested in the analog outputs.
when I start up jackd (from qjackctrl), I am offered three different options

for my sound interface:
hw:0     HDA ATI SB

hw:0,0  ALC892 Analog

hw:0,1  ALC892 Digital
(input devices are similar)
However, when I start up jackd, I get a constant stream of xruns.  This is

true regardless of what combination of input and output hardware device I

choose, as well as real-time settings and period size (I obviously haven't

tested everything, but a large representative swath).
On the other hand, if I choose plughw:0, jackd gives me a warning, but I can

get zero xruns and no artifacts for as low as 128 frames/period.
Similarly, if I start jack with the dummy driver, and then run alsa_in, I

can get down to 32 frames/period with no artifacts nor xruns.
What could be going on?
Thanks,

Jeremy
