Question Mi mix 4 USB audio - Xiaomi Mi MIX 4

Hello I would like to see if anyone here could kindly help me. Basically I have a mi mix 4 on miui 13 eu rom I have a usb c cable that connects to 2 pin iems the cable has a dac built into the usb c housing the cable works fine on my old phone but with the mi mix 4 occasionally there is a subtle static sound. My old phone doesnt support passive usb audio so a digital signal gets sent to the dac where it turns into analogue since it works on that phone the cable itself isnt the problem however I know xiaomi phones support passive analogue out the usb to 3.5 mm adapter it comes with doesnt have a dac in it and works fine with earbuds with a 3.5mm jack so I was wondering what I can do to fix this issue could a software update to miui 14 eu rom help or should I try pixel experience? Is there someway to make the phone not detect the external dac and bypass it because id be fine with using the internal dac basically by forcing audio adapter accessory mode. I wish I could find a cable that as usb c to two pin that didnt have a built in dac but it seems like it is such a niche thing. All this to avoid having to use a adapter lol

Usb audio out

I just bought GA and I have a little problem/question: I paired my Fiio e18 USB dac/amp with alpha with usb cable and I got an background continue noise. Could somebody try and tell me if it is a general bad design problem or is something wrong with my phone. From the headphones out sound seems to be better than s5 and note 4.
I don't have the issue with my Alpha and Fiio E18... Have you check if the Fiio and USB cables works perfectly with other device?...
So we can isolate where the issue come from.
I used the same combo with S5 dual sim ( 900fd) and with note 4. Maybe is a problem with the cable or the Dac. I will try with another cable, with fiio e17 and with note 3. I guess will find out who's the blame. I will be back.
P.S. The headphones output semms better than note 4 snapdragon.

USB-C Dongle that supports charging and audio?

I know its going to be the talk of the town for the Pixel 2 but I am wondering if if something that is possible with the original Pixel and if anyone has found a quality dongle for that purpose.
I have a car that doesn't do bluetooth audio but in my armrest I have a power port and aux port right by each other. I used to use it to power a bluetooth receiver but Google broke bluetooth audio to receivers with no volume controller in it with the "absolute volume" bug.
So now I am stuck having to use a cable, or two cables if I need to charge. Im wondering if there would be a way to use a dongle to merge that power and aux into a single USB-C cable to run out to the phone. Willing to pay for one with a decent DAC if one exists.

I bought Le eco type c headset, its premium quality, and also working good with my nexus 5x, but doesnt work with this elephone s8.... what I can do with the ugly usb-c - jack converter? thats only for listen music! But its mobil, so I need working headset LOL!
The USB-C headphone adapter included with the S8 is a dumb adapter and it does not have a DAC. If you want to use a DAC adapter, or headphones that have a DAC, you need to turn on USB OTG in settings > Accesibility and turn on OTG Enable.
THANK YOU

Thank you, thank you, thank you!
This is such a simple solution! I've been in the middle of trying to wrangle a refund/return for my Elephone USBc to headphone cable for the past week! Out of frustration I went out and bought a random one off Amazon...but when that didn't work I started to lose all hope!
I may still be out of pocket, for the time being, but at least now I can carry on listening to music!

USB-C Audio adapters

Hey all,
I'm looking to buy an tab S3 but I want to use it in a very specific use case where I need to use a USB-C to audio adapter (yes, I know it has a 3.5mm jack plug).
We have the tablet at work but because it's for a client I can't just tinker around with it.
I tried the USB-C adapter that came with the Google pixel 2 XL but that didn't work. The Tab S3 didn't play the sound over the speakers and paused when I plugged out the adapter as if it recognized it but I could hear anything. Does anyone have experience of a adapter that does work?
Also, does it work with the cheap passive adapters without a DAC? (USB-C audio can be analogue if the device supports it, other only do digital and require a DAC)

Question USB-C to 3.5mm for car auxiliary port

Hello!
I recently picked up a pixel 6, very happy with it so far except for the fact that my car is too old for the bluetooth to carry music to the radio.
I was wondering if anybody has managed to find a type c to 3.5mm cable that works? I have tried a type c to 3.5mm adaptor and it doesn't work, I think I need a straight type c to 3.5mm cable instead of an adaptor?
Before anybody asks, I have an fm transmiter but not really enjoying the experience between static or the bluetooth getting confused with the car itself.
I don't see why a USB-C to 3.5mm adapter shouldn't work. Try finding one on amazon that specifically advertises use in cars. It could be possible that the one you have is incompatible, manufacturers tend to make adapters that only work in specific circumstances.
You need an active adapter with integrated DAC (digital to analogue converter). Passive ones will not work. You better get the google cable if available. Apple one works but is too quiet in android. In fact any active cable should work.
Thank you both.
I have seen this one on Amazon, this is what I need I guess?

I use this one:

An alternative if you have 12v power in your car is using a USB Bluetooth to 3.5mm device like this one.

That way you can still be wireless and have Bluetooth in an older car, without having to deal with those hit or miss radio adaptors
I have this issue since using the Galaxy S21, the way I fixed it, start playing music on the phone speaker, then connect the cable, and it will start working, it happens all the time, that why I bought a cheap Bluetooth receiver from Walmart, best $8 I've spent in years.

I thought to do the same but the phone shows that the connected device is not supported

Just to clear up what that actually means for OP: a passive adapter will work only on USB-C ports that are able to route an *analog* signal. These are fairly uncommon -- most USB-C ports are digital only.
The nice thing about digital output is that you get to control the sound quality by selecting a USB-DAC of a quality that meets your needs, instead of being limited to whatever cheap thing they built in to the phone.
Physically, you can't even tell the difference any more. While USB-DAC's used to always involve a "big ugly box", the circuitry has shrunk these days to small enough to fit into the ends of the dongle.
The headphone adapter sold by Google is an example of this, its a USB-DAC, but shows no sign of containing any significant components besides the connectors.
I tried one that came with an old Motorola phone and it did not work, but Google sells one. They should be able to confirm if it works before you order it

I've personally tried 3 different ones that have worked for me, the first one was from an old Motorola phone, the second one, was one that I bought at an airport, I believe the brand is Moshi, and the third one was coming from a one plus phone. They all worked by playing on phone speaker and then plugging it.

Which Moto phone? My Moto Z(2) Force one gives an error message that the audio device is not supported.

It is the moto Z2 Force, I've used it a couple times, and I had no issues.

It works on your Pixel 6? Maybe mine is defective??
This discussion is very interesting. Generally pixel 6 (and previous pixels also) do not send analogue audio signal to the usb type c port hence passive converters from type c to 3.5 mm do not work. You need active converter with integrated DAC (digital to analogue converter) in it so that the digital audio from the usb type c port is transformed to analogue signal and sent to the headphones or whatever else. Every phone though has integrated DAC in the chipset because otherwise it would not be able to drive its own speakers with analogue signal. When i tried to connect my passive DAC adapter from oneplus 7 phone i got error on the pixel 6 that cable is not compatible. It is possible if you play something through the speakers analogue signal to also be copied towards the usb type c port and this way to trick passive adapters to also work but this need to be tested. I think that i still have the passive adapter somewhere and will test these days if i find it.

I tried an adapter from a Oneplus 6 (if memory serves) and I had the same problem, hence the thread
Given the one from Google looks just the same I am apprehensive to buy it until I am 100% certain
Today DAC circuits are so small that it is easy to integrate these into the usb type c part of the cable. There is no way to tell if cable is active or passive only by looking at it anymore. Google cable should work fine. Alternatively you can try the trick with first playing through the speakers and then connecting the old oneplus 6 cable and see if that will make it work. ne side note - don't buy the apple usb to 3.5 mm cable. It has very low volume on android (works properly on ios and windows). Tested it myself.

It would need to be physically wired together like that, which it is definitely not.
It would probably also need a second DAC built in, because there are only so many speakers you can drive with the built-in. That's why some phones are advertised as "dual DAC".
Got Pixel 6 usb-c to 3.5 mm one direct from Google...works great.

Is this for a car aux port or for earphones you use it for?
