iMAC sound problems after installing M-Audio preamp drivers
I recently installed an M-Audio preamp interface (MobilePRE USB) and their 64 bit driver ver. 1.8.0. It seems to work however the speaker volume on the mac (soundsticks and internal) dropped by ~ 50%. Also, the sound no longer works in photo booth as well as when importing movies into iMovie. I fear the M-Audio driver stomped on the iMAC sound driver. I've removed the M-Audio drivers with no change to the volume. Anyone have any ideas? I don't know how to re-install the MAC sound drivers.
3.06 GHz Intel Core 2 Duo 27" iMAC, Mac OS X (10.6.2), 6GHz RAM, HK Soundsticks
