Apple USB-C 3.5mm audio adapter low volume - Google Pixel 4 Questions & Answers

I have several of these adapters since I use Macs and iPads, but on Android the volume is way too low. I have seen several posts on the xiaomi-threads with a fix using alsa-mixer and tinymix. I have tried them all and none works. Does anyone have a hack that will make this adapter play nicely with my Pixel?

USB to 2.5mm Adapter not working

I decided that I wanted to use the USB to 2.5mm adapter that came with my device to connect my phone to the auxilarry jack in my car for music. When I hooke the adaper up the sound still comes from the device instead of the USB. Has anyone else had this problem.
Device info:
ROM 20273 from ppckitchen
Radio 2.42.40
Anyone else?
mine works freakin great
I may be dreaming, but I thought there was a problem with some roms and some adapters. Have you tried a different adapter?
No I just tried the one that came with my device. Evanbriggs which one do you use and what ROM are you running?
Edit: I see it in your signature. NM.
Does any sound come through at all? Do you get any sound when you wiggle the 2.5 mm Jack. Mine is kind of funny - I can't stick mine in all the way - if I do I only get mono sound rather then stereo - I have to push my jack in only a little more than half way to get stereo sound. All the way in results in mono - to far past half way results in no audio - Too little results in no audio. I suspected faulty adapter and never did test with another adapter though because I got tired of all of the wires anyway and just went with the Motorole T505 bluetooth and FM Stereo transmitter instead.
I get full stereo. Works like a champ with Resco Raido. i use a 2.5 -3.5 converter so i can use it in my truck.
I have not been able to get mine to function at all. I have tried wiggling, half way out, hlaf way in (lol). I cannot get it to funtion at all. I guess I will have to buy a diffrent one and try it. I was hoping to get some some Kitchen users to confirm which brand works.
I did this post about 6 months or so ago
Hi all, I looked at this and did fix it for the after market adapters a few months back. I have the same problem as you with the stock adapter and a 3.5mm adapter in it just too much of a pain to get it just right to work, the after market USB to 3.5 worked on stock ROM and then had issues with the DCD ROMs but not his fault as it was an issue with the 6.1 audio drivers, fixed by a simple wire snip in the adapter itself. If you do not get the audio to mute on the device when you plug in the USB then the line that grounds in the connector to do the mute and switch operation is not doing it's thing, suspect the adapter or connector in the phone. It is an 11 pin connector and quite complicated, so get an after market 3.5 to USB, find my post 6 months or so ago and isolate it to adapter or titan.
i had the same problem
my inline usb remote stop working for about 2 weeks..in fact the usb port just stopped working completly
my mogul wasnt being detected by the compute either but it would still charge
i thought i was a broken port but wen i boot into the bootloader while it's still connected it magically gets recognised by the computer
driver issues?
anyway activesync and the remote started workin again a few days ago...
but I know it will stop working again
stock usb to 2.5 never worked -rom prob?
My stock adapter has never worked. I bought an aftermarket usb to 3.5 and a set of headphones built with a usb plug and neither of those worked either. Still using DCD 3.12 from May. Is this a known problem with that rom?[/I]
Count me in!
And I thought I alone had these problems.
A week ago, I stopped receiving sound out of the left earpiece.
Two days ago, sound stopped coming out of the USB port altogether: It would continue coming out of the external speaker. Folks on the Metro gave me dirty looks as I tried this and that to restore the USB sound. I've tried two adapter cables (same brand, from eBay).
I have an XV6800 Verizon's OEM ROM (2.09)...but tons of software tweaks.
I may switch to BlueTooth. I have a pair of HP's BlueTooth stereo noise-canceling closed phones, for which I paid $100. But the on-off slide switch keeps turning ON in my commuting bag, and all I get is a depleted battery when I'm ready to listen.
I just tried on no2chemspre3 rom, I get audio out of the factory wired/2.5mm adapter. I have always had sound regardless of rom. I use the factory adapter and a stereo headset from my old ampd E816 (best phone in the world). I have never had a usb-3.5mm adapter or a usb-2.5mm-3.5mm combo to test though.
I am listening to some Dyslexic Speedreaders right now. Try a wired phone headset. Just to see if it would work for you.

[Q] Car not in stereo ... ideas?

I greatly apologize if this should be in accessories (I think it splits the issue), but my Droid 2 (and my Incredible) plays only on the driver's side speaker using the audio cable I have. Oddly, my iPod Nano plays in proper stereo. Does anyone have a clue why there would be such a difference? Please note: It is not an iPod cable (i know there may be some difference if it was). Thanks!
have you tried a different 3.5mm cable?
Would rather have an answer to the posted question (as then there might be some light shred on what cable to buy ... Again, the ipod plays just fine so there is something else going on). As always any actual answers are appreciated!
Well I have a droid 2 plugged into my 3.5mm cable and it plays stereo from default settings. There are many things that can be causing the issue, however a 3.5mm cable for $3.00 USD is most likely going to be the cheapest route for diagnosing. The lack of information provided is not going to help anyone assist you nor is answering facetiously. You have not stated if you have tried this cable in other cars/equipment or tried you phone in other equipment. That is another step that I would take in order to resolve the issue.
...
<sigh> Of course, it will not do this board any good to continue to debate the quality of a non-answer. Randomly buying new cables is not the answer to a technical inquiry.
I continue to hope SOMEONE WHO KNOWS will respond. Perhaps, for example, there are different types of stereo 3.5mm cables, and someone will say "Oh, the D2 requires a 3.5mm cable which has XXX; watch out they also have 3.5mm cables which have YYY, which is what you may have."
Anyway, if anyone knows, please respond, so that others who have this problem will find the answer on a search (even if it is on post # 6). Thanks.
Have you tried the phone with this cable in any other equipment or with any other system? A 3.5mm is a 3.5mm cable.
If you have a set of head phones, plug those into your D2, does it play audio on both sides? Or just one?
If the answer is just one side, then quite possibly its your phone that is the issue.
...
Despite what looked like a bad debate with theecho, we had a few back and forths via PM.
I tried a standard green cable from my computer system and it worked great. I note that cable I had been using was a "Sony" cable (dunno from what) - no idea why it didn't put out stereo on the Droid 2 (but did on the nano).
Hope to buy a non-Sony cable and see how it goes. Thanks all.
Hmm I think it might be the cable lol

For the record- there are at least two kinds of common 3.5mm plug. One has two bands and the other has one band.
The plug with two bands carries two distinct signals (left and right) that share a common 'ground' wire. This is called stereo since it carries both left and right channels.
The single band plug carries only one channel and is referred to as mono.
So if it's a mono plug, the iPod may detect that and switch to mono output.
You could test that by changing the pan in your car. If you hear different things from each side, you've got stereo. If they're the same, you might have mono.
I've seen plugs of each type used for non-audio purposes. TI has used those plugs on their data cables, for example. All that to say, it's very possible that you had an oddball cable lying around, and your iPod just handled it better.
Hopefully that gives you some of the underlying info you wanted.

Thanks for the info. I will add this to my arsenal.
I had this same problem. Turns out the plug wasn't in all the way. Try giving it a little bit of force. Droid2's headphone jack is a bit tight.
We'll know soon ...
Theecho - thanks for your public and private guidance!
mrkite38 - That is the information I was looking for and it makes sense. I mean, there HAS to be a difference (although I still don't know why Sony would make a mono cable).
I have a belkin cable coming from Amazon today (I was ordering something else for my Incredible, so I figured I would tack it on). We'll see how it goes.
I am having the same issue with a "cheap" cable and am eager to see your results.
Can either of you say whether the plug on the cable you're using has one or two bands on it?
That was it!
mrkite38 had the answer. The new cable, which is in stereo, has 2 bands; the old cable has 1.
Picture attached. That you Mr. Kite.
Sweet! Glad we got it sorted.

Reliable HDMI CONNECTOR

I've tried a couple of devices that claim to connect V20 to tv by wired usb c to HDMI connector. They work for a while then the picture is lost or the phone itself freezes up. About the longest play I've gotten successfully is an hour but usually something goes wrong within 15 minutes.*
The phone has been out over 6 months now so I thought someone may have found a really dependable HDMI connector? I don't mind the lack of power in because I can always change batteries but phone should be able to play through HDMI long enough to watch one movie. That's all I really need hut I don't want to have to screw around with it 10 times to watch one movie.
Thanks so much for your help!
I've been wanting to make use of this feature, but haven't extensively yet. I have though gotten to make fair use of a micro-USB to HDMI adapter. A few trouble spots come to mind here.
Sounds like you're powering the adapter/phone from an external power source? How good is that power source? My micro-USB to HDMI was distinctly less reliable when plugged in since I was merely powering it from a normal USB port. Try running it entirely from the phone's battery. If this works better then it could be you really need a higher power source when using the adapter.
How good is your HDMI cable? Depending on how strongly the phone/adapter drives the HDMI signal, a lower quality cable could break the camel's back.
I've been running into a different bit of trouble with USB-C to HDMI adapters. I've found several of these, but whenever they've got a USB-C pass-through, the pass-through is strictly for power and does not carry the USB signals. The MyDP specification allows for USB3 to be passed through if 1 or 2 pairs are used for the HDMI signal, but allows for USB2 to be passed through no matter how many pairs are used for the HDMI signal. There are adapters which also include USB-A port(s), yet none which include an external USB-C with the USB signals. Grr!
I use C to HDMI not micro usb. V20 doesn't use micro usb. It uses slimport. I have one adapter which allows simultaneous charging and one strictly slimport C to HDMI. Both behave the same way. I have a high quality 2.5 foot HDMI wire.
Power source was Samsung tv usb powered output 1 amp. Point is I have the same issue with pure slimport and no charging.
The one that allows simultaneous charging does in fact charge and work but always craps out but so does the slimport C to HDMI.
Hmm, entertaining what you find when you do research. I suspect the V20 is using the "MyDP" specification, which is the official specification name behind "Slimport". Seems there are at least two other video out methods for USB-C.
I haven't done enough with the video-out feature of my V20 to have much experience yet. With a V10 whenever an adapter was plugged in without external power there were no problems, but when an adapter with external power was plugged in video wasn't reliable.
I'm interested in reading if you find out anything.

Sorry I haven't tried, but its seems to connect smoother the a wifi dongle.
does anyone know if there's a compatible dongle for the V20 with not only hdmi but also power input and usb host?
Happening to me too - Any suggestions
Your situation's description fits my problem exactly. I have a USB C to HDMI that was vouched as working by several V20 owners. I plug it into my Dell monitor to play games on a bigger screen. It works well for a while, then disconnects and popup on my screen says something like, "LG Bridge has stopped working do you want to exit?". Once this happens, it's almost impossible to get the V20 to share the screen again. It's not a hub, just a USB C (male) to HDMI (female).

Wired headsets not recognized by my Pixel 4

Hi everyone,
I discovered that my wired headphone is not recognized by the Pixel 4 (audio still comes out from the built-in speaker.
Then I tried the Pixel USB-C headset from my friend (he has a Pixel 3) and it worked.
I also made it work with some Bluetooth wireless earbuds (probably not relevant, sorry).
Anyone would have any idea how I can make generic standard headsets (with USB-C connector, no adaptor 3.5mm to USB-C) recognized by the Pixel 4?
Thanks a lot,
Axello

I would definitely start the troubleshooting with the your usb-c to 3.5mm dongle. Sounds for sure like you have a subpar adapter. You stated that you tried a pair of wired usb-c pixel buds and had no issues, this would rule out a faulty USB port on the phone. Get your hands on a new or different dongle and give that a try, you should be fine with a known working one.
I have 3 of them (Pixel OEM dongles) and all 3 work just fine with multiple pairs of headphones. Let me know how you make out dude.
Thanks 1dopewrx05,
Before my 1st post, I tried a standard headset USB-C (I wrote no adaptor)
By now, I have also tried another headset but with an adaptor.
I'll probably try another one later when I get one but I think it Is strange and I was wondering if there something special with the Google Pixel Bud USB-C.
Thanks,
Axello
The Google USB-C to 3.5mm is special because it has a built in AMP to power headphones connected to it. If an adapter doesn't have a built in AMP then any headphones you connect to the Pixel 4 won't work using that adapter.
This is the reason your USB-C headphones don't work, it's simply because the USB-C port on the pixel 4 doesn't provide enough power to drive your headphones.

You need an adapter (dongle) that is a digital to analog converter (DAC). Not all brands of dongle's are interchangeable with the Pixel. I purchased a dongle from Google for a Pixel 3, cost about $12.
Good luck
Hi GTOJim,
Thanks for your reply.
That must be it. My previous mobile was the HTC U12+ with USB C headsets and I also had a USB-C adaptor and I guess the HTC one was the wrong technology.
I'll check for another converter then.
Cheers,
Axello

If I remember correctly HTC's wiring in their USB-C port is a bit different for their earbuds. A year ago I had USB-C earbuds from HTC and they didn't work on 2 of my phones(Samsung and possibly Pixel?).
Thanks Charkatak!
The HTC USB-C is probably not to be re-used then.
However, my converter 3.5mm to USB-C should have worked but I guess the DAC requirement wasn't there.
I'll just get another one

USB cable to audio jack

Hey just acquired an essential phone but it didn't come with the audio jack anyone know an alert antivenin that works I tried two active adapters from eBay but they both don't work.. Any suggestions TIA
Check this thread:
https://forum.xda-developers.com/es...ial-ph-1-list-compatible-usb-c-t3726018/page8
There are quite a few suggestions there for adapters that are confirmed working with PH-1.
It has to be an adapter with a built in DAC. (the more expensive kind)
there are other phones that basically use just a converter cable and output analog audio through the USB C port, since those are just changing USB C to a headphone jack they are pretty common and cheap.
The essential phone outputs digitally to a USB digital audio converter chipset built into the converter rather than just straight analog audio.
So just make sure the adaptor you are looking at says it has a built in DAC and it should work.
sometimes they dont list it though so if you are going for a cheap one then you may have to rely on someone in the reviews having an essential phone.
most razer phone and google pixel adaptors work but I'd still verify they have a DAC, sometimes amazon listings will just list a whole slew of compatible phones.
