Hello,
I recently purchased this small NVArcher BP1048 DSP Board.
It worked fine for the first two days, but when I came back the next day and turned it on, the output was extremely quiet. So quiet that it took me a while to realize it was even running. I did not make any changes in the software.
After opening the ACP Workbench software to see if any volume sliders where turned down, everything seemed to be fine. All the volume slider where roughly at +-0dB. I had to increase one of the volume sliders (PGA0 - Line_in_4_5) to +40dB (!) to get any proper output volume, but obviously this distorts the sound like crazy and still was not very loud.
I turned all of the "Audio Effects" off, to make sure I did not mess anything up there.
The board itself is running and the problem is the same in both AUX and USB Input mode. Also the same on both outputs DAC0 and DAC1. I tried using different input devices, different cables and different amplifiers, but the problem is always the same. As soon as I plug the DSP inbetween, it is extremely quiet.
I played around with selecting and unselecting a few things and experimented with some sliders, but without success. I tried to reset it to factory settings, but I feel like this did not reset anything. Visually I can not see any damages on the PCB itself.
Am I missing something? It seems weird to me, that it worked fine at first and instead of completely dying, it still runs, just extremely quiet.

As it turns out, the volume control via external buttons is different from all the volume controls in the software. And even though I don't have any buttons connected to these volume control pins, they were for some reason turned all the way down. After bridging the contacts to "press +" the volume is fine again. I will continue to observe whether it changes on its own again.
Hi Diesdasder , if you are able to integrate a Linkplay module to this pls keep us updated to the process.
