Hi community,
I am facing an issue with my headphone jack, basically i am having some buzzing noise coming from it. I can hear it n the headphone itself. With my mobile phone i do not have this issue.
Did anyone have a similar issue?
I have not checked the headphone jack before, as it didn’t have the need…
Don’t have buzzing on mine.
Do you get also faint / barely audible buzz on the speakers, too?
Does it happen only when the One Up is plugged into an USB-C charger?
Might be worth a try checking the routing of the interal speakers’ cables: From my past experience with other devices (Pinebook Pro) a possible culprit is one speaker’s cable being routed a bit too close to electrically noisy component (like power converter) and picking some noise and the whole analog section (including headphone jack) getting some electrical noise.
This could be the case inside the One Up, depending on how the audio is switched between speakers and headphone jack (e.g.: do they share ground?)
Only on the headphone jack.
It happens on battery as well.
I will try to get some time and check the internals and get back to you.
Thank you for your help @DrYak !!
I have opened the laptop, and took some pictures of the port.
@DrYak Do you have any guide/reference to isolate the port?
