"Line Out" dead (except for beep) after installing Buster

[jaja]

Hello,
After installing Debian Buster, the "Line Out" port quit playing audio (youtube, media players, etc.).

The audio hardware works when Windows-7 is installed; but fails when Debian Buster is installed.
So it's a software problem, not a hardware problem.

Audio works on two ports:

• - "Headphone" port;
  - "Side Speaker Out" port (gray).

but fails on three ports:

• - "Line Out" port (lime);
  - "Center/Subwoofer" port (yellow orange);
  - "Rear Speaker Out" port (black).

It is strange that audio works on "Side Speaker Out", but fails on "Line Out".

Computer:

• HP Pavilion p7-1126s
  AMD CPU

"sudo lspci -v" gives the audio controller as:

Code: Select all

  00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 01)
          Subsystem: Hewlett-Packard Company FCH Azalia Controller
          Flags: bus master, slow devsel, latency 64, IRQ 16
          Memory at feb40000 (64-bit, non-prefetchable) [size=16K]
          Capabilities: [50] Power Management version 2
          Kernel driver in use: snd_hda_intel
          Kernel modules: snd_hda_intel

Some procedures I've tried hoping to fix "Line Out":

• 1) Using "alsamixer":
  • - selected and tested all listed audio devices <F6>;
    - un-muted everything (M);
    - maximized the volume on all ports.
  2) Deleted "~/.config/pulse/", then stopped and started "pulseaudio".
  3) Killed "pulseaudio" and rebooted.
  4) ROOT login.

They all failed to restore audio to "Line Out".

I did get one curious output on "Line Out".
If I un-mute "beep" in the "alsamixer", the "beep" command will play a momentary tone on the "Line Out" port.
This beep is the only audio I've gotten from the "Line Out" port under Debian Buster.

I'd appreciate any suggestions or insights.
Thanks.

What often happens is people do not realize there are more sliders on the right, you need to use arrow key > to scroll right to see them. My 2¢.

Segfault, thank-you for your response.
Yes, I saw the "sliders on the right". That's how I discovered the "Beep" slider (which led to producing the only sound I've gotten on "Line Out").
Thanks for taking a shot.

Try installing the firmware-linux-nonfree metapackage.

Try installing the firmware-linux-nonfree metapackage.

Hello Head_on_a_Stick,
As you suggested, I installed "firmware-linux-nonfree" into a fresh install of Buster.
It did not fix the problem. "Line Out" still fails to produce a signal.
Thank-you for the suggestion.
