Thanks for your quick reply.

I know I am running MME. I think my sound card is setup in Control Panel for 24 bit but I will double check when I get home from work.

I can tell you that the program suggested 120ms for the latency setting which I agreed to. It also suggested rendering in stereo rather than mono which I also agreed to.

The weird thing is that it worked right after the installation was completed. After the first song played, I started exploring the program, being careful not to change anything (look but don't touch), and then the same song did not play correctly. Makes me wonder what changed, why, and how.
