Logic Delta / Audiophile 2496, Logic crashes on Quit, general problems with Audiophile Options

G4/466, OS 9.1, 384 MB RAM, Logic Delta 4.6.2 (dedicated 40MB RAM), M-Audio Delta Audiophile 2496, latest beta drivers (v1.5.6b)

I am able to select the ASIO driver in hardware preferences, however if I try to record I get an 'ASIO hardware malfunction error -999' whether I select the analog or the S/PDIF source. While the rest of the app seems to work after that, when I quit Logic hangs up without any error message (mouse pointer is not frozen though), requiring a hard reboot.

Generally, I haven't been very successful to get the Audiophile to work AT ALL... Their drivers (especially the Control Panel) is a nightmare, preferences don't stick, the sound (through Sound Manager) is mostly awful and distorted. But I couldn't find out any pattern what causes the Audiophile work sometimes and what doesn't, it just looks like it has its 'moods' on its own.
I have reinstalled the card and the drivers many times, trashing prefs, to no avail.

This week I took it back to the store, they installed the Audiophile on their G4/400 (OS 9.1) and suprisingly (well, not really as a G4/400 is *not* the same as a G4/466, unfortunately) they were able to make the card's analog I/O work with MicroLogic 4.7.3 even by using the original beta driver and the ASIO driver that comes on the CD.
But then I have demonstrated the problems using the card with Sound Manager, and the symptoms were the same as on my G4, i.e. clicks, noises and a kind of short 'fade-in' effect if you play *any* sound. Finally, after my demonstration their Logic started to crash on launch with error 3 (illegal instruction), freezing the G4.
Nevertheless, the guys in the store tell me that the card *itself* appears to be working (which it actually really did, at least for a while) and therefore they can't take it back.

Has anybody ever been successful in using the Audiophile with a G4 (133 MHz bus)? If so, what's your secret?

Thanks for any help or advice

I found a couple of solutions/workarounds and explanations in a german forum, however until now I didn't look into it any further yet (I've been concentrating on the graphic design part of my work recently, you know...).

As far as I remember, the -999 error is related to the settings in the Sound control panel; I think you need to bypass the card *completely* in there, that means to set the I/O to 'built-in', if you want to use ASIO. ASIO2 works best with Logic, by the way.
The bad thing is that if you are using the internal QuickTime Synth, its sound will then go to the internal speaker. The workaround would be to use the built-in audio output and mix the QT Synth with the rest of your tracks on an external mixing console. (In theory, as I said I didn't try it yet.)

An important point in using M-Audio/Midiman devices seems to be checking their website very often for driver updates. Usually they simply post a new version without telling anyone. Sometimes the German site posts a new driver and they don't even tell the US division for 6 weeks.
They must be smoking some very heavy stuff those guys, I suppose... ;)

Actually as for now, with the latest drivers, if I go through the SoundManager it seems to work okay. But I have been only digitalizing some old vinyl records, recording with SoundStudio from the SPDIF input, nothing more (turntable --> amplifier --> DAT --> Audiophile).

As for the SPDIF out, now I suspect that the card must have *done* something to the coaxial input of the DAT, because recently I wanted to record digitally from a professional CD player and I coudn't get any signal from there either. The last time I've done something like that a couple of years ago it *did* work; and the only device I have connected to the DAT in the meantime was the Audiophile. And in the beginning the Audiophile at least 'tried' to work before it stopped completely. So I don't know...
