Hi,
Thanks. I started from scratch as you did, and now have Wifi disabled and bluetooth streaming.
The audio skips and gaps are still there unfortunately. I have ethernet plugged in, and I can see the following from the log:

The audio skips and gaps coincide exactly with the Missing RTP packet and SBC decoding errors.
