Many of the present decoders have fail back on usb in case the net connection is lost.This particular one is the Barix 500.The USB kicks in and the m3u files play but there is 5-6 secs of silence between songs,like tracking a CD.Kinda annoying on air ,but hey at least you're on air.Do any of you have a solution for this? Getting them to crossfade would sure sound better.The files have to be saved as playlist m3u. Thanks
