I have the same issues here with RDP internacional and Radio A1 (Hotbird on a VU+ Duo 4K with OpenATV.
If I make a recording, I can play it back just fine.
If I pause the sound for, for example 30 seconds, then unpause, I get sound.
But live radio is completely silent.
What I wonder is what people here say about normal PID's.
What was abnormal about the PIDs from those radio's that had the issue at the time?
I tested with Radios ESP as in the beginning of this old thread, and got sound on streams 2-7, whereas streams 1, and 2-15 were silent.
Here the same behaviour and no sound on RADIO A1 and RDPI Radio.
However if i first zap to the tv channel on the same transponder say: RTPi and next choose RDPI Radio or Radio A1
Then radio channel sound is there. So as a nicer workaround you can zap to RTPi first
