ReSpeaker Mic Array V2 microphone sensibility about kalliope

[Sispheor]

Kalliope mic settings is based on the system setting config.
It needs to work at the Linux system level to work on kalliope.
I know that for this kind of microphone you need to customize a bit the Alsa settings.

If you have used the setup script or followed the installation guide to setup pulseaudio you should be able to use alsamixer (Press F5 for all settings).
I use the respeaker V2 too and I can change the input volume with alsamixer without configure any alsa settings e.g. .asound.conf if you are using pulseaudio otherwise it may be necessary to configure a ,asound.conf.

And as @Sispheor mentioned if the respeaker works on the terminal with e.g. rec test_file.wav it should work with kalliope too.

Kalliope is working with Respeaker. But only if i speaker at less than 50cm from the microphone.
I installed Kalliope following the installation guide(Manually).
I have the following alsa message when i switch to Respeaker with F6

If you setup your respeaker as default in pulse with pactl list sources short and pactl set-default-source DEVICE_NR you should see in alsamixer as "Device" (or in your case "Carte"): PulseAudio.
Then you can just use F5 and set capture to a higher value.
