Feedback on my problem with the sound on a stream. Today I downloaded ProgDVB version 7.46 and tested the same stream first with no luck so I switched to ProgTV and it worked and after shutting down ProgTV and restarting ProgDVB it worked there as well. It seems that version 7.46 solved my problem

depended from codecs or audio renderer?

In LAV Video decoder I made a change :
Under "Hardware Acceleration" I choosed to use Intel Quick sync as Hardware decoder but I dont know if that is what solved the problem ?
