RE: Pimoroni DAC SHIM - Tim Curtis - 09-26-2021

Very odd.

What the output from amixer command?

Code:
amixer -c0

RE: Pimoroni DAC SHIM - DRONE7 - 09-26-2021

I see the O/P is using a Pi Zero so should the dtoverlay be #37 HiFiBerry DAC or #38 HiFiBerry DAC/DAC+ Zero ?

RE: Pimoroni DAC SHIM - Tim Curtis - 09-26-2021

Those are both assigned dtoverlay=hifiberry-dac.

Maybe the board has a weird volume range and MPD volume needs to be like 80 or something like that. The amixer output might show something.

RE: Pimoroni DAC SHIM - timbo22 - 09-27-2021

amixer and and amixer -c0 return nothing,
speaker-test responds as does alsamixer but there is no response with amixer -c0

what about the output from...

Code:
aplay -L

and

Code:
aplay -l

Can you also post a screenshot of the alsamixer view ?

I have verified that the volume control wheel on the web interface is at 50.

I hear nothing...

I use a zero w + audio dac shim in my kitchen without any problems (LS2 = hifiberry dac). I think the problem is the connection between raspberry and dac without soldering. That's why i soldered the audio dac shim . I recommend a test without any housing. This is the only way to make this audio dac shim from pimoroni functional without soldering.

I have a test without a housing, I have not soldered it i admit but I did contact Piromoni and they stated it should work. I intend to house it in an old radio and so need to make this as compact as possible. As soon as I have it working I will commit to soldering until then I didn't want to mate a potently dead board to my pi. Your point is taken and I may yet commit.
