I've tried to use mixer but UINT mixerGetNumDevs(void); returns 0?

Hi,
Is there any way to make the speakerphone work while connecting? Once the call connects it works great, but for example if I'm driving, I want to press call, hit speaker and go and know it's ringing, instead of waiting for it to connect before the speaker initiates.
Im suspect there is no noise cancelling on this phone which Samsung built it.
How to enable noise cancelling when in call??? Samsung dont want to answer
and also why this phone keep switch it display on automatically when in idle (switch off the display)
Yes it did. The 2nd mic is in the back under small notch of back cover. That's the noise cancelling microphone.
If you don't want the screen to turn off there is a setting for that.
Unfortunately the second mic does not work for noise cancellation during calls. Only for video recording. The hardware is not present to use it during phone calls.

That seems rather silly. I was wondering if this was the reason groove ip behaves so differently than on my other phone but I guess not if it's not being used...
Hello,
We purchased a used GN the other day from someone on Craigslist. I checked the phone out (or I thought I did). Went through camera, speakphone, wifi, gps, no water damage and so on.
But after activation when using the internal headset we get a static noise that you hear through out the call and the other party does too. If you change to speakerphone all is clear and sounds great. Switch back to headset and the noise is there again. You can press mute and the other party no longer hears the static.
Is this a mic issue?
If you press mute the other party will no longer hear anything. It does sound like a front mic issue to me.
There is static noise whenever i make a recording. The weird thing is that there is no such noise when i speak in a telephone conversation. Is this something common ?
Edit: Ι did a service test using *#*#7378423#*#* and i found that second microphone produces static noise if you don't speak close to it.
Hello everyone, a while ago I dropped my phone and now the main mic is broken (the one near the charging port). So I can't record audios or make calls without using a headphone with a mic. BUT WHEN I RECORD VIDEOS THERE IS SOUND. I think that's because of the noise cancelation mic(the one on the upper right side of phone) For some reason it's activated during the video records and captures the sound.
How can I force my phone to use secondary microphone all the time? So that I can make calls and record sounds without changing the primary microphone.
well, I'm not a programmer but I have been trying to edit audio_policy. conf and audio_policy_configuration.xml files.
Apparently there are 2 input sources for microphones. built-in mic and built-in back mic. I have tried deleting these or somehow ' disabling' them. but nothing happened. I can still capture sounds while recording videos but the very same damn microphone wouldn't work while recording voices.
How hard is it to simply disable the main mic and use the noice cancelation mic as the main one? I'm sure you programmers can figure it out better than me ??
I'm facing the same issue, have you found any hack for that ?
Any luck bicho2015? My main microphone died on my Pixel 4 and I would like to reroute to the other 2 built-in mics.
