So sound used to work in my Linux distros. I use Qubes OS, Tails, and Fedora. All used to have sound but lost it for whatever reason even after fresh reinstalls. Pavucontrol in Qubes OS gives me "Dummy Output" as the only output device. Tails's sound manager gives me the same error. Initially it gave me an HDMI Unplugged error before I reset my BIOS configuration. I know you guys like terminal outputs so here's some. The commands below were run inside of Tails which is debian based:

amnesia@amnesia:~$ speaker-test 



speaker-test 1.1.3



Playback device is default

Stream parameters are 48000Hz, S16_LE, 1 channels

Using 16 octaves of pink noise

Rate set to 48000Hz (requested 48000Hz)

Buffer size range from 192 to 2097152

Period size range from 64 to 699051

Using max buffer size 2097152

Periods = 4

was set period_size = 524288

was set buffer_size = 2097152

0 - Front Left

[2]+  Stopped                 speaker-test

Another command:

amnesia@amnesia:~$ ps -C pulseaudio

  PID TTY          TIME CMD

  7801 ?        00:00:00 pulseaudio

  8678 ?        00:00:00 pulseaudio

And one more:

amnesia@amnesia:~$ aplay -l

Other info: This is a laptop. The internal speakers output no sound, and earphones aren't detected and don't output sound.

From what I am gathering from research, my OS isn't recognizing my soundcard, but it's weird it's happening for three distros. I'll be happy to follow advice from you all.

Here's the issue: QubesOS kept deleting drivers. Previous laptops I had never required sound drivers from Windows, but this laptop does. Message for QubesOS user experiencing this issue: set your Windows partition to readonly. This will probably eliminate corrupting. You can also use USB sound cards which have a wide support.
