Mac SE sound messed up with Radius accelerator

[RadRacer203]

Just installed a 16mhz Radius accelerator in my SE and I can definitely see the difference, it's significantly faster than stock. One quirk I've found though is the sound seems to be messed up. There's a lot of static in any music or anything more than just a simple beep. I'm stumped, do I need to install special software for this Radius board to fix it? I'm not sure where to start. I did confirm it wasn't the logic board by swapping in a known perfect one from another SE.

What OS are you running, and yes I'd install the official Radius drivers for the accelerator.

I believe I'm running some version of system 6. Thanks for the link, I'll install those drivers

Looks like the drivers solved it! That was a way longer process than I expected cause I wasn't set up for making Apple disks yet...

Hey I know this is a very old post but does anyone have these drivers?? The site doesn't appear to have them any longer unfortunately.... Thanks in advance!

Hey I did find an actual download of the site on Macintosh Repository.. Not sure if this link will work https://www.macintoshrepository.org/download.php?id=10431&go=1 Either way the vintageapple.org site is archived at the Macintosh Repository for future reference.

Actually that is a download link. Here is the valid link https://www.macintoshrepository.org/8258-mac-drivers-museum-archive-1990-2003-

Did the drivers fix the sound problem? I have the 25mhz board and I don't have any sound issues, though I only tested after I installed the drivers, so I can't confirm whether the problem existed without them.
