Hmm - no success so far. Maybe a post of my complete code helps in finding the error:

These are the global compiler settings:
Processor: STM32F407VG
Family: STM32F4xx
Board: MBHP_CORE_STM32F4
LCD: universal
The encoder as well as the update on the LCD with every turn is working quite fine. But the PGA does not seem to transmit any audio…
Thanks for patience,
