I was attempting to do a little LP conversion today and the sound output was awful. I'm wondering if it's a USB thing going on, since I had to get a USB sound dongle when the internal sound on my Mini went out a few months ago.
If you can get to the tweeters glue up the cracks, it may put you through without the distortion till you can get some. If possible a flexible epoxy or something. I wonder where you could find something like that.
