I have given this station a test again now, and still fine. Am assuming you have not started running a VPN on your network which would give the appearance of being in a region that FIP does not stream to? I believe they have their own native app; if you install that on your phone or try streaming from their main website player, do they work okay?
Could you please try going to the audio settings in Sense and make sure you do not have a maximum sampling rate limit applied? Please make sure it is set to no limit:
No problem - we found an odd exception where the sample limiter was affecting how AAC format was being played (which happens to be the FIP format). A lot of stations run on AAC, but many use MP3, hence why you would have had mixed results.
Thanks for the report!
