I’m using " amixer set Speaker 100%" to turn the volume all the way up, but the sound level coming out of my mini-speaker (via USB sound adapter) is barely a whisper - but it is definitely audible. Do I just need a bigger speaker? Lower Ohms? Different “amixer” settings?
Anyway, here is a link to the audio adapter:

and here is a link to the mini-speaker.
Here is the output of the “amixer” commands:

Playing WAVE ‘/usr/share/sounds/alsa/Front_Center.wav’ : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
The result is a barely audible female voice saying “front center”.
Any help/guidance will be greatly appreciated !!!
