5:03 p.m.
My studio machine has been around for a while - it's a 3GHz P4 (with
hyperthreading! Ohhh, 2 cores!) and 1GB RAM. I have 2 M-Audio 1010s
for 16 channels of I/O. Over the past week, I modified the machine to
use a 500GB Seagate Constellation SATA hard drive as the primary OS and
archive drive, and an 80GB Intel X25-M SSD to record to. I also installed
Fedora 12/CCRMA so there was the question of how performant that would be.
On top of everything, it was the first session in my new studio space,
having moved at the end of last year and needing some time to get the
space into shape. This was just an overdub session, but the system
performed very well - not a single xrun all evening - and the new space
was comfortable and worked really well.

One last note on the session: since the mixing/control room is separated
from the performance space, and we were just doing overdubbing, I tried
something new. I used X11vnc to send the studio machine's screen to my
laptop, and I easily controlled the overdubbing in Ardour remotely. This
impressed the musicians quite a bit! I'd hate to do more than simple
transport and record-enabling that way though - the studio machine has 2
monitors each running at 1600x900 for a total display size of 3200x900.
Displaying that to an older laptop with a 1024x768 screen was interesting!

Congrats ...
What is/was your jackd command line? Or the parameters you used for
period size, sample rate etc.
thanks,

/usr/bin/jackd -P70 -p512 -dalsa -r44100 -p128 -n2 -D -Chw:1 -Phw:1 -m -H
A note about my setup: I have 2 Delta 1010s that have an S/PDIF connection
for master/slave clocking as detailed here http://delta.brainiac.com/deltasync.html
If I need more than 8 channels, I'll use the devices multi_capture and multi_playback
rather than hw:1. And why hw:1 and not hw:0? At one point I had an IRQ
conflict with one of the 1010s and my Ethernet device, so I had to move
the PCI card for one of the 1010s to another slot. Somewhere along the
way this switched the order of the two cards, and I've used hw:1 ever since
rather than re-wire my patch panel or switch the cables that connect to the
breakout boxes.

Hi,
Hmm reading a bit through this link http://delta.brainiac.com/deltasync.html
"Note about SPDIF cables, these cables are not the same type of cabling
used for analog audio, the internal resistance of the cable is different
than for analog audio. Although analog RCA may appear to work, it is not
reliable. Examples of SPDIF cables can be found at www.hosatech.com"
I just bought a cable for experimenting a bit with spdif. But apparently
I didn't bought the right one, but a 'normal' audio cable...
Regards,

Yep, you need the kind of cable labeled "digital coax", like the ones
used for connecting a DVD player's digital output to a surround sound
receiver's digital input. They have RCA connectors but don't work well
as analog audio cables, and vice versa -- analog audio cables don't
work well as digital audio cables.

The 'digital' ones should work fine for analog as well. But
they are probably a waste of money in that case.

Check your soundcard docs, one of red or white is spdif "in" and the
other is "out".

Sorry so late ... I can't find anything regarding 'in' vs 'out', but
manufacturers seem to agree when there is only 'out', that it is yellow
