Laptop > No Sound Output > Advent Monza V200 >

Hi there guys.

I was hoping that you could help me with an issue that I’ve been experiencing

I’ve helped a friend of mine resurrect their old laptop.
It’s a fairly old-ish machine, but still usable as a spare
(See details at bottom).

It originally came with Windows 8.1, but was later upgraded to Windows 10.

However it was running excruciatingly slowly on Windows 10
2+ mins to actually boot, 40-45 secs from hitting the Windows / Super key for the menu
to appear, The Wi-Fi was broken, etc, etc.

I’ve swapped out the old HDD (5400 rpm) for a 1 TB Samsung SSD, and its much faster
and usable.

Issue:

The sound refuses to work.
There is no sound outputted from the built in speakers, at all.

Troubleshooting:

I’ve done a good bit of googling, and this seems to be a fairly common issue.

Un-installed and re-installed ALSA
I’ve blacklisted a couple of (what I believe to be) the incorrect sound modules
But I’ve returned it to the previous settings, as it had no effect.
Ran both Kubuntu 24.04 and Linux Mint 22.02 (via a live USB) -
the sound has not worked on either live environment.

Using a Fedora live USB stick

Tried sound (via internal laptop speakers) = No sound output.
Tried sound (via headphone jack) = worked - Sound was outputted perfectly.

Now back using OS (Ubuntu) via the main / internal SSD drive

Tried sound (via internal laptop speakers) = No sound output.
Tried sound (via headphone jack) = worked - Sound was outputted perfectly.

So the sound on the laptop is not completely broken (which is great news).

It just won’t (currently) output sound via the laptop’s internal speakers

Questions:

Is he sound totally broken ? [Edit - No it’s not]
If not, what do I need to do, to get the sound working ?

How do you test the sound? I do not use Kubuntu. On Ubuntu it is System Settings>Sound>Output Device>Built-in Audio>Test.

Could there be a physical break in the wiring from the Sound card (electronics) to the speakers?

Regards

Given that the issue occurs across multiple live distributions, and the headphone output works perfectly, this strongly points to a hardware issue with the internal speakers or their wiring rather than a software or driver problem.
On older laptops this is unfortunately quite common. Using external speakers or headphones is the most practical solution unless you want to open the device and inspect the internal speaker connections.

@graymech
I was using the Kubuntu equivalent to test the audio
on the internal speakers
(It’s very similar / the same as what you have posted).

@graymech & @MesterPerfect
I suspect that you may be correct, that this may be a HW issue
rather than software.

Annoyingly I cannot remember (for certain) if the sound was working on Windows 10 (very recently).
I believe that it was, but I cannot say for 100%

Thank you both for taking the time to look into this issue for me.

It’s much appreciated.

If you you install and use pavucontrol does it help? If you can get headphone sound then it sounds like you simply need to switch the output to speakers

geordiejedi · January 4, 2026, 6:45pm

@Actionparsnip

I’ve installed and tried pavucontrol (thanks for the heads up about this programme).

The issue remains - No sound output from the laptops internal speakers.

However (annoyingly) I can see the audio meters moving up and down
in time with the changes in an audio stream, when viewing
a video or music file.

So the resolution to the sound issue is either tantalizingly close.
Or there is a HW issue that’s preventing the audio from accessing / leaving
the laptops speakers.

MesterPerfect · January 4, 2026, 7:20pm

At this point, with audio meters active, headphone output working, and the same behavior across multiple live distributions, this effectively rules out a software or configuration issue.

This strongly points to a hardware problem with the internal speakers or their wiring (very common on older laptops).

Unless you want to open the device and inspect or replace the speakers, using external speakers or headphones would be the most practical solution.

You’ve done all the right troubleshooting steps — there’s really nothing obvious left on the software side.

Actionparsnip · January 4, 2026, 9:20pm

Is there a hardware switch on the system to increase and decrease or mute the audio? If so, try that

1tsme0707 · January 5, 2026, 2:40pm

i would say it is not a hardware issue. i am having the same problem, but my laptop is not old. On top of that, my laptop is dual boot one windows one Ubuntu in windows side everything works perfectly fine. Headphones too. i would be very happy if i am able to fix it but how ?

geordiejedi · January 6, 2026, 7:27pm

@Actionparsnip
Another good shout, but no.
There is not hardware key to enable / disable the sound / speakers.

Thanks though.
