[Alsa-user] how to automatically detect and use connected usb audio devices

[Mgr. J. C. <jan...@vo...>]

    Please, does somebody of us know, if is it possible to configure The 
Linux operating system so USB connected audio devices could be auto detected 
and can be used for sound input and output?
I AM using KNOPPIX_V8.6-2019-08-08
I do not want to use Pulseaudio sound server, I want to only use ALSA. I 
have many reasons for that, better sound trebles, better responsivenes while 
using it with Espeak text to speech engine.
If somebody of us know some package, stand alone app, which can autodetect 
and automatically use selected USB audio device with ALSA without Pulseaudio 
sound server, please let me know about it.
With kindness regards.
