Phone Call Configuration - Cannot be heard on phone calls #499

Open MatthewABrantley opened 1 year ago

MatthewABrantley commented 1 year ago

Steps to reproduce

  1. Open Settings App -> Sound
  2. Open "Configuration" submenu and change to "Phone Call" configuration.

OR

  1. Take a phone call

Expected behavior

For the "Phone Call" configuration to have a configuration which picks up my voice.

Actual behavior

The device will no longer be picking up noise, until you close the settings app and then re-open and set it back to "Default".

To further confirm, I installed alsamixer and watched what happened to the input levels when I changed from "Default" to "Phone Call". It immediately reduces "ADC Input" from 100 (Or whatever you set it to) to 19, and always 19.

Logfiles and additional information

Attached! journaldump.txt

I didn't know I was having so many MMS issues after reviewing my journal, looks like I'll be looking into that next. Sorry the journal is so filled with MMS noise. I am currently trying to figure out how to edit "Gnome Sound Configurations" for lack of a better term so I can compare "Default" to "Phone Call".

I think I found how to fix this. This is currently setup in PinePhonePro-VoiceCall.conf

    # Set capture volume to 0dB so modem audio doesn't overdrive the ADC
    cset "name='ADC Capture Volume' 47"
    cset "name='Mono ADC Capture Volume' 47"

Microphone is okay with postmarketOS and these lines are like this:

    # Set capture volume to 0dB so modem audio doesn't overdrive the ADC
    cset "name='ADC Capture Volume' 160"
    cset "name='Mono ADC Capture Volume' 160"

So I think these should be the default setup? This works (tested today) - but there is issue that somehow microphone drops lower if I answer call which comes when PPP is suspended. I don't know where it comes from but it is the same with pmos.

I looked for "ADC Input" in the alsa controls, @Raltrwx , but I couldn't find it. Has it been renamed? I'm running 6.3.5-1-danctnix right now.
