Need the advise from our Linux experts here.
I noticed that the piCorePlayer running with Hifiberry Digi+ seems to have the gain being set a bit far too high.
My wee class-D amp simply gets into distortion mode prematurely.
If I'm using the USB output from RP2, I can SSH in and tweak the Audio Output Level by changing the gain via Alsamixer command. But, it is not working out with Hifiberry Digi+.
The piCorePlayer path : /usr/local/sbin/config.cfg shows that
ALSAlevelout="Default"
Is there any way for me to play around with this command ?
I wonder what is the acceptable range of gain level that I should enter...from Min to Max
