debian+phosh running on PinePhone

[buffer]

Oh wow, during calls the other person cannot hear me but I can hear them. I can't figure out why!
Did you have to configure anything first? Did they work out of the box?

Everything modem-related works out of the box, but it's recommended you disable PIN code verification on your SIM card.
Mobile data should be enabled in Settings -> Mobile on first (and sometimes, second) boot.

Well actually I DID all that, I have 4G reception and everything modem related works, and 1) PIN code verification is not used on my carrier as I do not need to use any PIN codes 2) is disabled by default on the OS 3) we need to define "calls work" because if calls "work" then am I the only one here who has this problem (see below):

I've been trying to troubleshoot it once a day every day. Trying to verify that it wasn't my own doing, I:

• eliminated the possibility of data corruption by using only unmodified images from your website running off the SD card without resizing the partition.
  
• I tried various possible sound settings: Default, Phone, Internal/External, this and that.
  
• Initially I just thought that the mic worked and I was getting an echo, but I eliminated that possibility by using earbuds and muting the mic on the other non-pinephone: with that done, zero sound is picked up by the physical microphone
  

At the time of writing I used the March 15th image.

Today I encountered a weird thing, that occurs when setting is to Phone Call, output device is Internal Earpiece, and input device is Internal Microphone: on the other line, you can hear scratchy noises, and internal sounds. So, you can hear scratchy internal notification sounds (drip, glass, sonar, etc, but not bark) and you can hear scratchy sound of a youtube video I downloaded and played in mpv to test. I am sure it is coming from within the software, not that the microphone is picking it up, after all at no point when I speak directly into the microphone does it pick up my voice.

 Another interesting thing is that when I plug in the power cord you can also HEAR on the other line, the power transference when I plug in the cord and when I run programs that increase power consumption such as apt. (I have now heard apt singing to me in electric, and my life is forever changed.) It makes sense that the microphone would pick up noise from the power cord since they are right next to each other...

But I am certain that software settings are supposed to configure the microphone to pick up the correct sounds. I always suspected it to be a microphone problem. I'm not saying that it's a modem problem at all. Just that when people are saying the calls just work, I know people are leaving out a key piece of information: unmute or configure the microphone before your calls will actually work. So far I've yet to hear from other users here about what they did, hopefully one of them can shed some light.

As for how to do that? I did check out alsamixer settings and even on the sound card itself, but I couldn't figure it out: the microphone on the default view is already unmuted. There are also a handful of microphone related settings on the sound card itself which mystifies me. I did hours of research but I'm in the dark. If this configuration was included out of the box, that would be really useful. I will put it on the wiki at least.

I get no sound when I tried recording with gnome-sound-recorder to test the mic with different settings. I double checked all settings. Recording is silent.

Thanks in advance I do appreciate the work you're doing on this distro and I want to contribute ports etc. Hopefully another user here can confirm the issue or clarify the workaround or share some documentation.

Checking alsamixer again (press F6 - select 1- Pinephone sound card), I see that when I change mic profile from Default to Phone, or from Phone to Default, in phosh sound settings, both Mic1 and Mic2 are muted. However (press F6 again - select 0- Default) on the main menu the capture device remains unmuted. However, unmuting the mics does not help make sound get recorded.
