Hooked the Archos up to the MiniMe over the weekend and fed it about 5 minutes of 16/44.1.
The thing locked up to the MiniMe immediately and I was able to record to it using my picturebook as a control source. Unfortunately my results were consistent with everyone else's. Audible glitches in one or both channels at intervals of ~19 seconds. I will be using EAC to do a wave compare to find out the exact interval and number of glitches, but based on what everyone else has found I think we know what the results will be.
I'd be happy to do any testing of future firmware releases, so whoever has a good dialog open with Archos, be sure to let them know that we have a crew that will be happy to work with them. Based on what we're finding I'd say we are doing a little more rigorous testing than their QA group so they should probably take us up on that.
