M-audio Revolution & Tiger issues?

I picked up a M-Audio Revolution 5.1 soundcard a couple of days back, and put it into my PMG5 which's running Tiger. I seem to be having a lot of distortion problem though - audio tends to start fine, play for a bit, then get worse as it jumps, and is generally distorted. The odd thing is that switching modes in the driver software (switching between "None/OpenAL" and "SRS CircleSurround II") seems to sort the problem out briefly...

Is anyone else having this problem? Does it sound like a driver issue or something hardware-related?

sounds like a driver issue.

clock sync messing up possibly? Have you tried changing the sample rate from/to 44kHz/48kHz?

Have you downloaded and installed the latest drivers?

There are some subtle changes in the way Tiger handles audio devices that will require driver updates for most devices.

Another problem a lot of revolution owners have, like myself, is that the computer will not shut down properly and requires a hard reset. Do you have that too?

It's happened to me twice; both times VLC crashed, failed to force quit, and when I tried to shut down all other open applications refused to quit. That's twice out of the two-dozen or so times I've actively used the card. I think that at both times, I was switching modes on the soundcard drivers, possibly at the same time as a track was changing in VLC.

It isn't a general problem, though - other than those two crashes the system works (and at those rare times, shuts down) perfectly. Except for the annoying distortions.


The drivers I'm using are the latest ones available, but they are not certified to work with Tiger. I tried the card in a Windows machine, and had no problems, so it does indeed appear to be the drivers that's the problem. I would try the card under Panther, but I only have the one mac with PCI slots, and said mac has taken a disliking to my Panther install disks.

I guess it's just going to be a case of waiting for M-Audio to update the drivers, and hope that solves things...

analogika - where should the sample rates be? In Audio Midi Setup, or elsewhere?
