Speaker is not shown as output device in gnome nor alsamixer

This week I installed Debian 10.9 on my desktop computer, however the speaker is not shown as output device in gnome nor in alsamixer.

The hardware if fine since the computer has Windows also, and the speaker works.
alsamixer shows only:

Code:

Card: PulseAudio                                     F1:  Help               │
│ Chip: PulseAudio                                     F2:  System information │
│ View: F3:[Playback] F4: Capture  F5: All             F6:  Select sound card

and only master.

Code:

Selecting the sound card with F6 in alsamixer I have:
│ Card: HD-Audio Generic                               F1:  Help               │
│ Chip: Realtek ALC892                                 F2:  System information │
│ View: F3:[Playback] F4: Capture  F5: All             F6:  Select sound card  │
│ Item: Master [dB gain: -17,00]                       Esc: Exit               │

but the speaker is not present in the mixer.

I have not found any similar issue in the Forums. It is important to note that I also tried other distros like Fedora, Pop Os but the same issue happens.

I have never seen the speakers listed by alsamixer either. This is normal.

Is sound working on your system? Could you describe what ever issue you have.

The headphone output works fine, however speaker output is not working, that is, no sound .
In Gnome volume control, there is only headphone or line output. There is no speaker as output to select.
Sometimes the speaker give some clicks, even on headphone output selected.

The hardware is working fine, since I also use Windows in same computer.

When you are trying to use the speakers, make sure you do not have anything plugged in the headphone jack. That will mute the speakers on most laptops.

Bring up Pulse Audio Voluse Control. Look at the tab called Output Devices. Make sure that is set to Speakers. Set the top slider soem where to the right. Play something, do you see any indication on the line below that shows output? Music shouldd cause it to move back and forth.

The pavucontrol has no speaker in the output device. There is only headphone and line.
But, it embarrassing, I tried again disconnect the headphone, as you suggested, and the speaker is now working. :-)
Willl reboot to check it again.

Thanks you for the advice. I have never seen this in a desktop, to have to disconnect the headphones to get speaker to work.

Glad you got it working. Sorry for any confusion I caused thinking this was a laptop. FWIW, I have a similar system.

At times I have trouble getting sound out of my head phones, speakers always work as expected. As far as 'speakers' on that 3rd tab, that was from my laptop, in the desktop its Line Out or Headphones. I leave both plugged it all the time. I have noticed in brackets after Headphones I see ( unplugged ) and ( plugged in ) after Line Out. This is only on the desktop. The laptop always shows the correct plugging on Port selection.
