I've got a MacBook Pro that I use in a band situation to playback 4-channel audio files. Channels 1 and 2 contain the backing track files that go to the left and right audience speakers. Channels 3 and 4 are a "click" track that go to my headphones. I accomplish this by using an Aggregate device of: channels 1 and 2 are Built-in Output; channels 3 and 4 are my Roland Duo-Capture USB audio interface.
Everything has been working fine for years, until a couple days ago when I installed two new apps:
Wondershare for mac
Wondershare Player (Mac) - Download
Hear
Data Recovery Software | Download Free Trial for Hear | Prosofteng
After installing those two apps, I discovered that suddenly my multichannel audio files did not play properly. Instead a get a loud buzzing/static sound coming out of the USB interface. I'm stumped as to how to fix it. Here's what I've tried:
- removed both apps, problem still exists.
- reloaded the Yosemite 10.10.1, and reinstalled the Roland USB interface drivers, still no luck.
- I changed the speaker configuration in the Aggregate device so that channels 1 and 2 play through the usb and channels 3 and 4 (that normally to to my headphones from the usb) now go to the default-output. And then the buzzing/static came through the mac speakers -- so, it's not a problem with the USB device since it occurs occurred with the built in speakers.
- Any thoughts? I thought re-installing the OS would solve the problem, but it didn't.
