Microphone 1 ch

[jeccsron]

Hello.

I installed Blackhole 2ch in orden to use in OBS.
Now I uninstalled it, but my microphone changed to only 1 channel.
How can I change or reset to get 2ch estero as before?
Perhaps the audio settings are corrupted.

Thanks

EDIT:

I can see what happened. I have an old MacBook, the microphone is 2ch.
So I assumed that this M1 too.
Then when I saw 1 ch after I deleted Blackhole, I thought there was an error, but it is normal.

Look at this:

Does anyone can confirm this?
