Understood. I think for us to solve this, we need some info from Bonkel.
The old mediasink file you have linked is dated mid Dec 2015. my azboxsink repo has not changed since Sept 2015.
Do you have later mediasink files from 2016 where it's working or broken to narrow down when it started failing? (And attach to he thread)
Different things could have happened.
HDMU was using a different mediasink in Dec 2015 or made changes to the bb recipe.
Or changes made to servicemp3 in enigma code broke this.
But as same e2 code works when swapping the mediasink lib, there may well have been an recipe change of sorts. But only HDMU team can confirm this.
edit: I had a look at the strings in the gstdvbaudiosink.so. And I can values that were not in my mediasink back Dec last year.
For example, I always had following definebut in the old working sink, its showing without the "framed =(boolean) true".#define LPCMCAPS \
"audio/x-private1-lpcm, " \
"framed =(boolean) true; "
which is the way it is in christophecvr's repo. I'll adapt that change and create another mediasink test build
