Since I read your bio does that mean if I come fix your µRendu you take me diving?
Yes no problem! I "feel" the microrendu's problem is the network and the power supply, not the device itself. I'm trying a new power supply which is helping, and may be removing the network issue by running a hardline ethernet from the NAS to the device, but it seems to me the microrendu may be taking a back seat in my system to a more fire-and-forget streamer. I literally cannot hear the difference between the MR and the RPi3 that I built, so either my hearing sucks (ignorance is bliss) or there's not that much difference.
Anyhoo you're always welcome to come dive the Vandenberg with me! Look me up if you ever get to the Keys.
