Today, when I went to record using my Eureka, I noticed that the VU needle is stuck in the middle - whether on or off - and no sound comes out of the unit. I used it just the other day and had no issues. Doing some research, I came across an old forum link that leads me to believe that either the input or output chip has gone bad (http://forumsarchive.presonus.com/posts/list/7881.page). Anyone else had a similar problem and/or have any info on how to fix? Thanks.
