I have a problem that has bugged me since getting the B2 - and now I have the solution.
I was about to post this (below) and then found this thread. Comments below
------------------
If I access "Internet Radio"/"BBC Radio 4" it will play, but after a few minutes the buffer will empty, sound will stop, and then, after about three seconds, the buffer will refill and sound will restart. This has very much limited my use of the device for radio.
However, if I access the web page and select vTuner/BBC/Radio4 it plays without a break.
This is a repeatable problem that occurs whenever I try "Internet Radio". What is this all about?
Using the web page has not been a convenient method so I have preferred to use the front panel. However, I now have spare Android devices to dedicate to the B2, so it now has its own screen.
The B2 is hard-wired to a high speed broadband service that supports iPlayer and other high bandwidth services without problems, the Android device is on wifi. I assume that the two methods of access to internet radio use e.g. different protocols or codecs or something else that means that different software is involved.
-------------------------------
I now understand that "Internet Radio" is giving access to presets, which may need updating. It isn't clear at all from using the front panel that they are presets, or that they are unreliable. I was expecting to be able to use the B2 entirely from the front panel. It seems that isn't going to be reliable.
