Hi, I own a Persons AudioBox 1818VSL USB interface and from two days I hear noise and scratches in Ableton Live.

I use Mac OS X ElCapitan.

If i quit Live, all the audio turn back to normal playback from iTunes and system sounds.

Your buffer is probably set too low.

Open Ableton Audio Control panel and adjust buffer to higher setting.

Larger sessions require a higher buffer.

If you're not monitoring audio for realtime recording, and you're only doing playback then set the buffer higher.

If you're playing virtual instruments, then set your buffer as low as your system will handle.

Also consider upgrading your storage drive to SSD or use External Thunderbolt drive for audio recording and avoid using system drive for recording audio for better performance.
