Is there a way to set ALSA microphone as the main one?

I’m using Kubuntu 19.04 and i’m getting weird pop sounds at my microphone whenever I talk. I’ve recorded my mic via Pulseaudio and via ALSA (thanks to Audacity) and I noticed that the pops only appear in the Pulseaudio’s record.

I’ve already tried a lot of config solutions (and even tried to disable Pulseaudio), but unfortunately nothing worked.

Is there a way to select ALSA microphone as the system default?

internal Microphone and Headphones Mutually Exclusive

When my headphones are plugged into the jack on the side of my laptop ( HP Omen 15-ax250wm) The internal mic is shut off. My laptop is set up to dual boot and this issue does not exist in Windows 10.

I’ve searched everything I can find on this issue and still came up empty when I tried each suggestion.

I have tried changing the setting with the input/our pins or something of that nature via hdajackretask but didn’t get very far as it seemed to change nothing. (I know very little about it as it’s super technical as far as I can tell.

I have tried sudo apt-get install --reinstall libasound2 sudo apt-get remove libasound2 and that utterly destroyed my system uninstalling apps left and right.

Why does this functionality work on Windows and not on Ubuntu? It seems as if that blocking of the internal mic on plug in of a headphone jack would be some extra functionality, some setting, some software. (Especially because it works fine on Windows)

Andoid Nexus 5X Microphone sound too low

Recently, about 4 weeks ago, the volume on my microphone became too low for listeners. I can hear them perfectly though.

I found somewhere on the internet (I can’t remember where) that if I clear the system cache (see below), then the volume returns to normal. Which it did.

It’s happened again though. So I’ve cleared the cache again and again the microphone volume has returned to normal.

Is there a way around this? It looks like its a software fault rather than a hardware fault.

These are the instructions I followed to wipe the cache:

  • Power off the phone
  • Hold down power and the volume down button
  • Use the volme up/down to select “Recovery mode” and press power button
  • When “No command” is displayed, hold down power and press volume up.
  • Select wipe cache
  • Restart

Currently on 7.1.1

Use bluetooth microphone in Google Assistant

I’m trying to set up my motorcycle bluetooth headset (BT-S2) to allow me to use Google Assistant. It has the following profiles:

  • A2DP-SNK
  • AVRCP
  • HSP
  • HFP

I’ve managed to find an old APK of ‘Smart Bluetooth Headset’ which has allowed me to map the normal ‘redial last number’ button to the more useful ‘Google Assistant’, and that seems to be working flawlessly, opening the assistant and making the normal beep awaiting voice input.

The problem I have is that it doesn’t pick up the audio from the microphone on the headset, only from the phone itself. I’ve tried various combinations of the settings within the Google Assistant, as well as various mono routing apps to try and get it to work, with one being successful at one point, however no longer using A2DP and forcing me to use a poor sound quality.

Is there any way I could either:

  1. Make Google Assistant correctly use the microphone on my headset

  2. Force the phone to use only the microphone part of my headset instead of the phones one, whilst retaining the A2DP mode for audio?

Microphone extremly quiet

For some time my microphone is extremely quiet when doing things like making voice messages on whatsapp or when calling someone. I searched the internet for a solution but couldn’t find anything except for some apps which didn’t work (or only worked in the app itself but outside did nothing). Is there a config file with the microphone volume so I can adjust it myself or some script or so?

Wired headset microphone is also extremely quiet.

Samsung G900f (S5)

Android 6.0.1 / Cyanogenmod 13

Internal microphone is not detected in ubuntu

I bought new laptop and install Ubuntu. In windows 10 microphone normally working, but not in Ubuntu.

I was searching for solution on forum, install pavucontrol and try left front microphone turn on 0, but nothing happens. Problem is, that in “input devices” I can find only analog input, not the microphone. THere are information about my alsa http://alsa-project.org/db/?f=0555ec30d7f888be63558f9558521d41c5afb35c.

Thank you for any help and tips.
