Mic and alsa troubles on my Pi Zero

[besi]

I am building a walky talky based on your wonder ful project

I was able to squish all the hardware into the laser-cut housing. I‘m thrilled that I got the playback to work. However, I‘m not yet able to speak to mumble.

I have a I2s Mic and DAC which work fine on their own. But for the mic I have to do the following for it to work, and I don‘t know how to translate this to your go-project (Also I‘m a more of a python guy, but you GOt me there) anyhow, this is how I use my mic on the command line:

arecord -D hw:0 -f SE_32 -r 22050 -V mono -c 2

Without these parameters the mic simply won‘t work.

So if you should have any idea or inkling on how I can get the mic working this would be wonderful.

Kind regards and thanks a bunch.

As a side note. I plan on releasing the plans and instructions soon on how I built my enclosure. It‘s written in openscad and uses a template from http://makercase.com/. I‘ll inform you once it‘s online.

I also reached out to Stackoverflow with this issue.

Hi besi,

Have you been able to get this resolved? I'm basically sitting with the same issue (using an WM8960 Audio HAT instead, though).
