Hi,

I have trouble setting the M-Audio Delta 2496 S/PDIF out for use with
an external DAC. This DAC will works only with 44.1 16 bits.

I choosed the WavOut S/PDIF as the source in the Patchbay and choosed
Consumer in the Digital Output Format and unchecked the Advanced
Settings. I even tried all type of Copy Mode without success. I
specified 44.1KHz but the DAC refuse to lock. I'm using WinXP and the
drivers available at the M-Audio website.

Thanks for any help.
Daniel

Try leaving in and out in monitor mixer.

Don't have my music DAW powered up at the moment (I have a Delta DIO2496
which is similar) but-- be sure you have selcted INTERNAL clocking for the
SPDIF output.

From the standpoint of basic clock locking, there's no difference between 16
or 24 bits, consumer or professional format. However, DACs can be fussy
about the electrical parameters of the digital signal. You can have ground
loops.

DACs can also demand certain odd settings of flag bits. If you told me the
"DAC" in question was a certain MD recorder's digital input I would say
"Been there, done that".

Hi,

The DAC is the little http://www.scott-nixon.com/dac.htm

It works with all my audio transport and the card works when connected
to an A/V receiver.

Shooting problems like this from a distance is almost a totally insane thing
to do, but I'm a wild and crazy guy.

Just guessing, but my long-shot guess is that you've got a grounding problem
in the digital domain, maybe a ground loop running through the ground line
on the DAC power supply IEC power cord. You might diagnose this problem by
trying a more conventional 12 VDC power supply, perhaps a conventional wall
wart (they are usually ungrounded).

As a digital signal source, the PC differs from the receiver and CD players
in that receivers and CD players typically have 2-pin power cords and are
usually not chassis grounded through their power cords.

If I've diagnosed this problem right, it indicts the digital input circuitry
on the DAC. It's not terribly unusual for perfectionist DACs to have more
digital interfacing problems than usual because their input circuitry is
often over-simplified, typically due the designer's to hysteria about
jitter.

Adding a series input coupling cap on the order of 0.01 uF, or a digital
isolation transformer might make the problem go away with just one part.

Open the M-Audio control panel. Click on the Harware Setting tab.
Select Internal Xtal. Select 44,100. Select Rate Locked.

That should probably do it.
