    Hello Guys,

    I just noticed that my stereo channels are reversed when I plug in headphones. Left is right and right is left. I tested differend headphones and the issue is still there while all of theese headphones work correctly on other devices.

    Already had a chat with german one plus Support and they told me to send a video related to this issue.. How should I create a video of reversed Audio Channels lol... ?

    maybe you can use a sort of app where you can set the balance to the left and right channel and show on the video that when you put it 100% on the left , the sound come out from the right speaker(driver, ear ...)

    Though about a Mod also but dont found Something usefull. I dont care about music or films because I use my bluetooth headphones for this but in case of gaming (PubG) i need low latency and a correct soundlocation in Order to hear enemies coming.

    I've been having the same issue. I'm not sure if its just the cheap amazon USB-C to 3.5 dongle that i'm using but its really annoying since the 7 pro is the first new phone i've had in years. I plan on testing another dongle hoping thats all it is.

    EDIT- everything works correctly with bluetooth speakers

    I never saw this, using a "Google dongle", and it was pretty cheap (but perhaps not as cheap as some).

    Installed a Qi coil though, so now I'm all-Bluetooth, the coil is double-sided-taped under my case (and as handy as all my other phones with wireless charging, I'm sticking with it).
    I thought I'd go nuts, not being able to use my old Bose headphones, but I just bought a decent BT-3.5 dongle, and plug them into this. Works well, except when I need to make a call, I couldn't find one that supported the full audio (mic) connection (I did a lot of searches, too).

    Anyway, I guess I'm just recommending the Google one, per above, in your case...

    @G_android_x14 USB 3-TypeC is *supposed* to be uni-directional, per the consortium, right?

    Are you saying some of these "knock off" USB-C dongles are only wired "halfway", or really, only "one half is wired correctly", on the pin-out?
    I'm not saying this isn't true, it could be some weird "deal" on low-budget adapters, but it goes against all the specs for USB-C...

    And now, I'm curious about this, to be honest (I've spent a good of my career working on h/w and s/w tests to assure standards/performance is "met", plus some actual-standards work, although I doubt most of these dongles were ever tested and certified).

    I have seen some dongles work differently when reversed. Usually around charging. It costs nothing to test the hypothesis.

    @G_android_x14 Yeah, sorry, I think I came across wrong here.

    I worked, for a lot of years, on "standards" for a lot of Win h/w, including USB (most 1.x, 2.x, and 3.0, was about the last work I did on USB, so no real deep-spec-knowledge of USB-C), and a LOT of tests to check standards and performance, plus test integrations (automation, including detection, and such).
    As such, my mind immediately sort of went to the "why would this be implemented incorrectly, seems like a spec/standards issue".

    When in fact, I mean to come across as "hmm, weird, I'm so used to seeing it to-spec, or very close", but I also meant, "I totally see the point in testing it", like you say, it's a 3-second test, to see if it works that way, why not, eh?

    3.5 plugs are "weird" like this, IME too, those standards are OFTEN implemented incorrectly, particularly if there's a mic-line on the plug, from some I've seen. That was out of my real purview though, more of an "audio thing", than a PC/Win thing...
    So I'm 1000% behind testing it, at least a couple of times each way, maybe a minute of testing for 2-3/ea way, and to listen to the audio, or use an track analyzer...

    one wrinkle with headphones is also control buttons. Android has no standard across brands. most manufacturer's rely on resistance reads to signal button functions, so results vary.

    forums are full of "my headset/selfie stick" buttons don't work" too.

    But yeah, USB c should work regardless of orientation if implemented correctly.

    @G_android_x14 Yeah, good point, I have 3x3.5 headsets, and the darn buttons (except the volume controls, those are "mostly" consistent) are a total crapshoot.
    They might do what you "expect" on one phone, long/short-press, or they might do something completely different, depending on the phone, headset, firmware/OS build, you-name-it.

    It'd be nice if they'd standardize these, for Android, some day...

    This was one of the nice things about working on Win, we were trying to work with OEMs/IHVs/ISVs, to have "common standards", so users could expect a "repeatable experience", consistently.
    Android has some standards, but in many areas, it's still the "wild west" of sorts, IMHO...

    I am facing issue with the OnePlus 7T pro Maclaren edition. when i plug the headphone and turn out the video or any surround sound audio the left sound is right and the right sound is left.

    Support are just downright ridiculous at times. They blindly follow a script like bots..... my god a video of reversed sound :how stupid

    Laws of probability states that he would have already used both sides equally..... Assuming he doesn't have it plugged in all the time

    It's something else

    I am also having the same issue. I am using a OnePlus 8 with a cheap USB-C to 3.5mm dongle. I have been using it for 2 weeks but I noticed it only after I started playing PUBG.

    Am using OnePlus7pro, I had the same issue with jbl quantum 200. Bought OnePlus type c adapter and it fixed the issue for me.
