I'm using Raspberry Pi running minidlna to serve music (over WiFi) to a Android tablet running Bubble UPnP, and then redirecting it to a wireless speaker with Bluetooth. It works most of the time, but sometimes after a few tracks it stops every minute or so for 10 seconds. I guess something in the pipeline is not fast enough to keep up, but I'm not quite sure how to identify which part. Can anybody advise? I can't see anything in the minidlna logs - is there anything it will report that can help me?
