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

you seem to be the man with the answers.

Hmm, well, I don't know But I'll try...

I'm inputing from turntables

I'm sure you know that you can't plug a turntable directly into a line input, except if the input is labeled 'phono' on an amplifier or a mixer. (But one never knows, that's why I'm mentioning it anyway.)

I'm not familiar with any flavor of Cubase at all, so I can't tell you exactly where to go and what to do. But since it most likely uses the ASIO drivers, in this regard it should work like Logic.
Make sure that the Delta ASIO driver is present in the ASIO Drivers folder on the same level as the Cubasis app lives. If there's no such folder, create one. Most likely the correct driver is ASIO2 DeltaAP, at least that's what Logic Delta wants.
Then make sure that the I/O in the Sound control pamel (SoundManager) is set to Internal (CD).
In Logic you can open the Delta control panel from within the Logic Audio Hardware Preferences, I assume in Cubases it will work the same way.

You might also want to install Logic Delta that came with the card just for testing purposes. Check out the included PDF manual how to set it up.
