Ibook Audio Puzzlment

Hello all

I have a strange audio problem that I can't resolve.

I have a G4 1.33Ghz iBook running OSX 10.4.9. 

Weird: Audio skips or is distorted in if playing through either the internal headphone socket or my firewire audio device (an M-Audio Firewire Audiophile) but not if playing through the onboard speakers. The distortion is not fuzz - it's hissy, squelchy and intermittent, almost as if the sound were being played through an effect (though not one I'd ever want to use). I get this with iTunes (CD and mp3), with playback through the Finder, and with Peak.

Weirder and weirder: when I use Logic Express with the Firewire audio device or the internal headphone socket the sounds do not distort. However, certain individual sounds - ie specific samples or tracks - within songs don't play. When I playback through the internal speakers these sounds do play.

What I've done so far:
• run repairs in disk utility
• reinstalled Tiger and updates
• reinstalled the latest M-Audio driver
• junked Quicktime and iTunes prefs
• checked that audio output is set to 44.1

Does anyone have any further suggestions?

Thanks and best wishes

Bouncing And Asio

Hello all
My problem is that when I work with ASIO I can't bounce down to a stereo file. With Mac AV it's not a problem. When I hit bounce in the environment window I get the following message: 'Mac AV is not available'.
If I switch to Mac AV then I lose all my plug-ins. I'm using OS9.2, Logic 4.8.1 and a Waveterminal U2A USB interface (humble, but who cares?). I'm working with audio only - no midi. (I realise that the OS9 forum might be the place for this query but it's no doubt of such a basic nature that 'getting started' seemed a better place for it.)
Thanks for listening.

Mac Av/ Asio Switching Problem - Logic 4.8.1

Hi

I was travelling over the holiday and did a lot of work on sample-based compositions using Mac AV and headphones. I clicked OK when asked to assign objects to Mac AV instead of ASIO.

Now I'm back home I've tried reassigning objects to ASIO. On several pieces the bassier samples are now distorting. These are samples that had been fine before I began working with Mac AV. Other samples are fine in both modes. I'd much prefer to be able to work using ASIO but I don't want to have to re-import the affected samples and reset all the hyperdraws and plug-ins.

I'm using Logic Platinum 4.8.1 with Mac OS9.2 on a fairly recent Ibook with lots of RAM (plenty of which is assigned to Logic). I have an EgoSys Waveterminal U2A USB box.

Thanks for listening
