Your ALSA mixer settings prove that the Master volume channel is being muted in gnome-alsa mixer:

Kindly unmute it.

# Simple mixer control 'Master',0
# Capabilities: pvolume pvolume-joined pswitch pswitch-joined
# Playback channels: Mono
# Limits: Playback 0 - 64
# Mono: Playback 50 [78%] [-14.00dB] [off]

How to vary it. I’m not cmd professional.

One more thing. In the sound preference; there is no tool to arrange. The only device is dummy Output.

First of all unmute with gnome alsa mixer. Still no alteration. The only hardware device is dummy output. Thanks
