Good evening,
I am currently facing an IT issue that surpasses everyone I talk to about it (sound problem with all the peripherals I plug into my PC) but that's not my question since I can live with it.
However, what I would like to know, as the title suggests, what could the two jack sockets on the screens be for?
I know one is meant for audio output, but the other... I've searched high and low, and I can't find anything about it; on the manufacturer's website, it's supposed to be an audio input, but my PC doesn't detect anything and I can't force it to recognize it through manual detection...
So I turn to you to understand how all of this works and maybe finally find a solution to my audio problem once and for all.
I have a portable PC Aorus x5v8:
i7 8th
1070
16gb ram
AOC 24g2 screen
connected via a Thunderbolt 3 USB-C port from my PC to DisplayPort; the problem is the same with an HDMI to HDMI cable.
Thank you for your responses!

hello
(sound issue with all devices I connect to my PC)
my devices (screen, printer, etc...) produce no sound - except if they are broken - they make noise when they work or when I tap them to encourage them
the sound card outputs sound through additional speakers

A thank you is appreciated.
Mark as resolved if your issue has been solved. I use 'tu' with everyone.

Yes, that's exactly it. The screen indicates that there is an audio line-in, but all the audio devices I connect to it are not detected.
By all devices, I meant audio devices, headphones, headset with two jack outputs, USB headset...
Otherwise, yes, the PC's speakers work normally, the screen's speakers also work, and my headset works perfectly when I plug it into the jack (headphone) of the screen.

line-in is for a microphone

so it works...... or not?
the signal would go through the cord to the PC?

Good evening,
Since this screen has a VGA, the line in must be a simple audio input.
Because VGA does not transmit sound, an additional jack cable is needed.
The other connections, HDMI and DP, should transmit sound.
Basically /
>>> the line in must be a simple input
(you can even test by plugging in a portable player or your phone with a jack cable)
>>> The headphone jack is indeed an output
(since the screen does not have built-in speakers, it is necessary to connect headphones or speakers to get sound)
You wouldn’t be fooled into thinking your screen has built-in speakers when it doesn’t, would you?
----------
Not easy to understand since you encompass everything.
And / or
If you think that your PC itself has sound issues.
Test on another screen like your TV for example.
Try the different video outputs
What does it give?
So we know whether the issue comes from the PC or the screen.

So I'm currently connected via DP and the screen has speakers, but everything else is true, you're right, the audio input is meant for a phone or a portable music player or a pre-amplified microphone.
I know I wasn't very clear in describing my problem, but I can assure you 1,000,000% that the sound issue comes from my PC, given my countless unsuccessful attempts to resolve it, spending time changing devices without success; I've already tried 3 screens, 2 headphones, and a good number of cables and adapters...

If I could give a piece of advice to anyone passing by here, never buy an Aorus laptop. I’m not the only one complaining about issues like this, and sound is not the only problem with this laptop (completely buggy DP port, both USB-C ports buggy, impossible to connect a USB hub without issues, recurring crashes). It's only 2 years old, I sent it in for warranty two months ago, and it came back in the same condition because the customer service teams found nothing.
For the price, take your way; the power is there, but you need to be able to take advantage of it first...

Well, we don't know much more, the issue could be from the screen or the PC, or either one...
You're 100,000% sure it's a problem, you've done x tests, x times with no results, and you are annoyed and convinced.
Sorry, not mean, but if you had done things properly, you would have at least pinpointed the issue accurately.
You need to go back to basics and test "separately".
Screen level
Can you provide the full reference because there are different models with a similar reference?
For example, AOC 24G2U5/BK, or AOC 24G2U/BK...
It's listed at Darty and LDLC, but there's no information on this level from the manufacturer.
Have you ever had sound on this screen? If so, by what means?
----------
PC level
What does the PC output via HDMI to your TV?
If you click on the sound icon at the bottom right, do you see your TV as a choice for output?

Don't worry, I don't take it the wrong way. I know you are here to help me. If I assert that the problem comes from the PC, believe me, I've already done all the little tests separately to locate the problem, except that I'm not super knowledgeable about computers, but from what I could draw as a conclusion, the problem comes from the PC and I even think it's a power surge issue because:
- I have problems when displaying games on a secondary screen connected via mini DP (I tried 3 screens with 3 different cables each time).
https://youtu.be/Vt1zI88M9T0
https://youtu.be/8Ymv-xxQsmg
- I have recurring disconnection-reconnection issues with my peripherals when plugging them into a USB hub or with an adapter on the USB-C port (on the desk)
https://youtu.be/_yAea1LMVN0
and I have the same problem but only in games on the Thunderbolt 3 USB-C port
https://youtu.be/hQzruKifwXI
- I have no issues with audio output; I've always had sound without problems. The issue is with sound recording because either I have a headset that connects via USB:
when connected directly to one of the USB A ports on the PC, the microphone is terrible, but the problem is resolved with the use of a hub (but I have problems with USB-C hubs, while the classic USB A ones work well with ONLY the headset plugged in; otherwise, there are reconnections and disconnections again...)
I have a headset that connects with a dual jack, directly to the ports of the PC; there are no issues with audio or the microphone, except that after a certain time, it starts to crackle and saturate like crazy, which explodes my interlocutors' ears. It returns to normal when it wants, it can take 30 seconds to 1 hour, even a reboot doesn't change anything. The settings don't change anything; I can only wait.
To bypass this problem, I noticed the jack ports on my screen, but in the end, that's not the solution because the microphone jack needs to be powered by the transmitter, which is not my case. So, I bought an external sound card that I connect to the integrated USB hub on the screen, and everything works smoothly now.
I still have some crackling (the PC shuts down and then tries to restart, but only the fans spin; the rest doesn't start. The solution is to force it off, then unplug the screen and restart, and then it works) most often in games, but it also happens on the desktop.
My current screen is: https://www.fnac.com/Ecran-AOC-24G2U-24-Noir/a13872031/w-4#omnsearchpos=1
So, I think I have covered my problem. I went to see advisors at an LDLC store, and they couldn't help me. I went to an independent IT consultant, and he couldn't help me either, but both mentioned power supply issues; that was the only thing they thought possible.
The PC went for warranty repair 2 months ago, but without success.
If you have any leads, I am open to suggestions.
Thank you!

You give concern and your conclusions at the same time, I still haven't quite visualized the issue :-)
It's not easy to jump on this train already at full speed.
You actually use your phone like a super tower.
Test all your problems with the minimum connected to your phone and see the differences.
Without keyboard, mouse, and game controller, just the keyboard touchpad commands from the PC.

I have already done these tests and the results are the same as with everything plugged in at the same time.
Yes, sorry, I'm not necessarily clear, but I didn't want to write a 300-page document giving you all the details; I didn’t have the energy, and that would have disgusted you.
Otherwise, yes, I use my laptop like a desktop because I move around quite a bit.

Always use the least possible USB on the PC and in case all your electrical connections are on the same power strip or outlet.
Test with extensions by plugging the devices into different power outlets.
(or even not using the current one but using others)
and
Do you have another laptop to test your setup with?

So I have a problem when the PC is plugged into a power strip and into a wall socket.
In two different houses, the issue persists; I can't test the power supply, as it's a special one for my PC. Otherwise, I have another laptop, but there's no problem with it.
And anyway, the power supply has gone in for warranty at the same time as the laptop.

We should be able to have proper functioning, then put things back and see the differences for guidance.
PC without USB equipment (you still have the adapter on USB-C Thunderbolt 3)
In HDMI or DP, simply a cable, do you still have these white stripes on a screen?
If yes, we will continue to search with this mini setup.

Currently, I have no problems because I have worked around all of them. I connect my monitor via the Thunderbolt 3 port on my PC using a USB-C to DisplayPort cable, and I connect the USB hub of the monitor to the USB-C port on my PC that is not Thunderbolt 3. The hub being integrated into the monitor, it is powered by it, so no more disconnection-reconnection issues (due to the PC's power bugs). Finally, I bought a USB sound card to connect my jack headset via USB to the hub of the monitor, so the microphone works perfectly.
The problems still exist, but I have always found solutions to work around them.

I think you're absolutely right because when I plug the microphone of my headset into it, nothing happens, but when I plug my phone in via jack and play music, my PC detects that sound as a microphone input.
Thank you very much, you've found the explanation.
