I bought an external jack plug mic.

Documentation says it suppose to be plug and play but i got nothing.
I copied the command in below link and execute but nothing changed.

How to activate external microphone?

Hello and welcome!

But it seems that your ULTRA is not correctly installed, have yoi followed the tutorial here? ULTRA++ installation guide

For the external mic you should use the right plug jack and acltivate input 2 in the mixer
SO it is this script:

I installed ULTRA+ driver following the guide but i did not get the GUI device input, output menu and audio mix GUI as specified on the guide. However, my onboard microphone and onboard speaker (also external) works. I can record and play sounds files

When i executed “amixer scontrols” i got Master 0 and Capture 0 only. As a result, i can execute commands to control Master and Capture. Looking at the script, it has Speaker, Headphone, etc

Here is my amixer command output:
pi@port:~ $ amixer
Simple mixer control ‘Master’,0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 65536
Mono:
Front Left: Playback 65536 [100%] [on]
Front Right: Playback 65536 [100%] [on]
Simple mixer control ‘Capture’,0
Capabilities: cvolume cswitch cswitch-joined
Capture channels: Front Left - Front Right
Limits: Capture 0 - 65536
Front Left: Capture 40 [0%] [on]
Front Right: Capture 40 [0%] [on]

This is solved. My card number is 2. So i had to append -c 2 to each command like below to work. What remains now is how to make command stay after reboot. Or do i have to run the script every time that i boot up?
