How to disable internal mic if external headset is connected?

by flag

I have a small problem with Ubuntu 22.04.2 LTS, every time I connect my headset via Bluetooth, the default mic is the internal one, this is not happening with the sound. So I have to manually switch the mic from the internal to the external all the time. Do you know how can I disable the internal mic if an external one is connected? Thanks in advance!

Have a look at the man page for amixer:

$ man amixer

There are some commands in there to select/activate the devices.

For example I use this to turn off my microphone:

$ amixer set Capture nocap

Hope that points you in the right direction!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
