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

dj, try the following setup:

Monitor Mixer: all channels open
Patchbay Router: set to Monitor Mixer
HW Settings: DMA Buffer 1K, Sample rates 44.1KHz, 'Rate Locked' and 'Reset Rate' are checked (unless you need to work with another rate of course).

Important: do not launch the DeltaPanel from within the Sound control panel, it won't work properly. Just set up the Sound c.p., close it. Launch DeltaPanel, make your setup, save it, close it. Once again launch Sound c.p. and check if evereything is 'still there'.

With the latest driver (v2.0) and control panel (v1.7) this seems to work quite well in my case.
(Still the same G4/466 with OS 9.1 here, except that now I have 896MB RAM, but that doesn't really make a difference, I suppose.)

Also, I can report that I have been quite succesful in setting up a small studio running Logic, a Roland XP-10 synth and an R8 drum machine. The only failure so far seem to be the missing SPDIF output with the ASIO driver, wheras SPDIF Out with SoundManager finally works after purchasing yet another VERY thick RCA cable...
