I measured around the digital input with a multimeter. The result was obviously a fatal damage....
No matter which input is selected, the DACs input does not lock.
Independently from the volume, while no input is locked, there is an output - see plot.
The 74HC244D (or 74LV244D) has been replaced, but still the same problem.
Do you have any idea, if this can be rescued?
Best wishes

Don't know where the 244 chip is in the circuit offhand. Don't know what dac chip is being used. Do you by chance have a schematic? What damage are you referring to? Can you also provide hi-res close up pics of the dac board so we can read part numbers and sort sus out the circuitry? Otherwise, you post is kind of cryptic. Not much to go on to help you.
