I recently bought the Audio DAC SHIM for my Raspberry Pi 3 B+ as I was unsatisfied with the low level of audio available through the built in 3.5mm jack.
I’ve installed the SHIM, and after some playing around I’m able to select it as my output device, but the volume level is still really low. I’ve tried adjusting it in the AlsaMixer but I can’t change the volume there and have the error message: “This sound device does not have any controls.”
Is there a way I can control the volume?
Thanks in advance,
