hey shayne,
  just a question about your settings: you have

input channels: 16

 does this mean you can record 16 audio channels at a time?  i didnt 
think the emu/sblive supported more than recording 1 input audio channel 
at a time... could you explain your setup?

thanks, wayne

well, i've managed to get my FC3 setup back on track - after much
stupidity messing around with alsa cvs drivers, i finally did the
sensible thing and settled on the previous alsa packages (had to fully
delete /lib/modules/2.6.11-rhfc3ccrma.rdt, or whatever, to get this
kernel and its alsa modules working again) ... the 1.08 alsa for EMU10K1
provides the multi-channel *capture* patch, luckily enough, so i can do
without the multi-channel playback for the moment.

things are looking mighty fine with this current setup, though:

*rtirq assigns priorities and interrupts as it should
*alsa starts up fine :)
*system is rock-solid with these settings in qjackctl:

input device: hw:0,2
ouput device: hw:0

input channels: 16
output channels: 2 (you can leave input/output as '0' in qjackctl)

sample rate: 48000

frames: 128 (seems pretty rock-solid even down to 64 frames, but i won't
confirm that until i've had a pretty good recording session at that sort
of buffer)

priority: 62 (is this correct? i changed this setting cos that's how i
interpreted Fernando's info about jackd using this priority now)

realtime: 1

unlock memory: 1

looking good - thanx for the help on this one Fernando!

shayne
