Not sure how to diagnose this but:
I haven't used WACUP in a while, but today when I started using the latest preview build, I'm getting random freezes every couple of minutes when playing my DJ mixes. The playback just hangs and then starts playing again a couple of seconds later.
I'm not having issues with playing the files with foobar.
It's off a HDD but there are no errors when checking the HDD health with various HDD checking software.
If I can do anything to help diagnose the cause please let me know.
