CastBridge playing BBC iPlayer Radio slow - sounds like record on wrong speed

Hi.

This is an odd problem... It doesn't seem to be happening on Tidal or locally stored files - although it's harder to tell with music than spoken word. I don't have any other live radio set up so I can't really compare it. It's not happening on anything else (Classics, Boombox, Squeezeplay).

I am running nightly builds of LMS, all plugins up to date, LMS is on Raspberry Pi Raspbian.

Any ideas?
