DisplayPort Alternate Mode over USB-C - Google Pixel 4 Questions & Answers

do the Pixel 4 finally have the ability to output HDMI through the USB C port so we can play with the desktop mode ?
Go rid of the Pixel 3xl because of this (and the effing usbc earphone jack)

[Guide] How to enable USB audio on Nexus 5X

The Nexus 5X's USB Type-C port can both input and output audio, however mine needed some setting up before it would work.
I plugged in a Blue Yeti microphone into the Nexus 5X using both the USB Mini-B to USB Type A cable (comes with the Yeti), and the USB-A female to USB-C male adapter from Google. The Yeti powered on instantly, it's red light turned on, and I could hear myself through its no latency monitoring via headphones (Blue Yeti has a 3.5mm headphone output), however the 5X would not recognize the Yeti as either an audio input nor as an audio output device.
I went into Developer Options, scrolled down to "Select USB Configuration" and changed the radio button selection to "Audio Source". I scrolled down even farther to the Media section, and there I disabled "Disable USB Audio Routing" (you might say that I enabled USB audio routing). There was no immediate effect, so I unplugged the Yeti, plugged it back in, et voila! The phone recognized the Yeti as both a microphone AND an audio playback device simultaneously.
I don't know for sure which of those two settings truly made a difference, as now that I've got USB audio to work, neither of those settings seems to make a difference anymore -- it seems as though my Yeti is permanently approved for USB audio in my 5X!
The USB audio works for listening to Google Music, and even for regular voice phone calls.
Do you have a USB microhone/headset/headphones/DAC? Get a good USB-A female to USB-C male adapter and you'll be quite pleased! And hopefully you'll be luckier than I was and it'll just work when you plug it in, but if not then toggle those USB audio Developer Options as described above.
Finally someone has posted on audio out and in via USB c! Thanks!
Just plugged the 5X into a Focusrite Scarlett 18i20. The phone recognizes the first two input channels and can record in mono or stereo (input 1 as left track and input 2 as right track).
Also it does seem as though you must keep the "Disable USB audio routing" off for it to work.
Sweet, guess I won't need the SoundAbout app anymore.
This is really nice. Able to route usb audio to a Cambridge Audio DacMagic. Much better than the on-board dac, and no longer tied to a specific app.

[INDEX] LG NEXUS 5X Resources Compilation Roll-Up
Isn't this just a USB sound card over OTG? I plugged in a Logitech sound card with line out and mic in and it worked without any tweaks.
My 6th gen iPod nano plays usb audio perfectly fine on my crappy pioneer deh-3300ub headunit, but no matter what settings or cables I try the stereo says "N/A USB" with my N5X plugged in.
Anyone get the audio-in-via-usb to work with the built-in Google camera/camcorder app?
I am using Nexus 6P
The audio-in DOES work with this video app: https://goo.gl/Dtu14
But with the built-in camcorder, it only records audio from the phone's mic, not the usb mic.

I would think google designed it to only use built in microphone. It would take some mods or tinkering to get it to do otherwise.

Can you test and report which apps can record audio with the blue yeti? free and/or paid, if you have the time to test of course.

That's because you most likely did just get a basic 3.5mm to USB-C adapter with no active circuit. I'm fairly certain that Nexus 5X do not support analog passthrough over USB-C, which means you will need something with active circuitry.

You need a portable DAC (get a cheap one like Fiio A1 for 25usd). Nexus 5X USB-C is not USB3/3.1 interface, so it won't work.

Route Audio Through USB-C Port Instead of Headphone Jack

My LG V20 has USB-C and so does my LG monitor. I plugged my phone into my monitor and it displayed the screen and charged the phone. Then I plugged a USB mouse and keyboard into the other USB ports on the monitor and they both connected to the V20. So when I'm home I can use my V20 just like a computer with one USB-C cable.
Is there any way I can route the audio out the USB-C port instead of the headphone jack? So the sound would go to my monitor. My speakers are hooked up to the audio jack on my monitor.

in developer option there is an option to route all audio through usb...about half way down the developer menu
i use this when i connect my gaming headset with an otg adapter, hyper x clouds with full 7.1 emulation, it is amazing.
hopefully there are no issues using that setting with video out, usb type c (usb 3.1) should have the bandwidth

My bad for the late reply. My app didn't show that anyone responded. I went into the developer settings and changed Select USB Configuration to Audio Source. It didn't work. All the audio still routes through either the headphone jack or the internal speaker. There could be an issue with the simultaneous output of video and sound. I messed with my monitor and didn't see any USB-C audio settings.

Bug with HTC USB-C headphones

I have found a strange bug in Pixel XL:
1. If I plug-in HTC USB-C headphones (that I got with HTC U Ultra) into my good old Pixel XL - they don't work (sound still comes from the speaker).
2. Even worse - USB-C port on Pixel XL stops working (until a reboot). It's not even charging from an AC charger!
Probably plugging-in HTC USB-C headphones crashes some kernel mode driver in Pixel XL
This is hilarious if you remember that both pieces of hardware are made by HTC!
Does it mean that we are entering a new era of incompatibility issues - some USB-C phones will not work with some USB-C headphones?
Btw, I have tried all combinations of USB related settings in Developer Options (USB Debugging On/Off, Default USB Configuration, Disable USB audio routing On/Off) - nothing helps (even after reboots).
U sonic headphones don't work with anything but the U Ultra

Type-C Audio?

Does Mi A1 supports Type-C audio output? Just bought a converter Type-C to 3.5mm and it doesn't work. But according to this one his earphone does work. Any idea? Or anyone tried with Type-C converter or other Type-C earphones?
https://www.youtube.com/watch?v=XxfAig8e2f4
I recently researched Type-C audio adapters as a possible way to get rid of the hissing sound. I read a lot of product reviews and it seems that most of the adapters do not work properly on android phones.
This is understandable because right now there is not enough demand (Android phones without headphone jacks are just coming out, and mostly they bring adapters out of the box).
My conclusion is that you have to wait at least another 3 months for good & proven adapters to come out. I assume there is quite some demand from Mi A1 users becasue of the hissing issue, so there will likely be good adapters for our phone in the future.
I strongly assume that Type-C audio output is supported because the Mi A1 is running stock android, which should have native supports given that phones without headphone jacks are becoming mainstream. But I am just guessing.
I found this under developer options. You can disable audio output via USB - which indicates that it is enabled by default (i.e. Type-C audio should be supported by the OS). No guarantees though.
Mi A1 does support audio output from type C port and I've been listening to music with my zorloo Z:ero headphones from day one using Meenova USB type C adapter.
Don't remember which adapter I got as Meenova were kind and sent me usb type C adapter back in 2016 to test my headphones on my LG G5. By the way Z:ero headphones have micro usb type plug so not sure if it changes anything. And they said that Not all micro-usb to usb-c adapter works, it has to be built for usb2.0 host operation.
Edit: not sure where half of my post gone but try and search for 3.5 mm to type C adapter that works with other type C phones and hopefully it should work with A1

Do you experience any of the hissing issue while listening over usb c?
i tested it with chord mojo device and it worked, but then, chord mojo standalone costs twice as much as the phone lol

Nope never experienced any hissing. Neither on Nougat nor on Oreo. It might be because the headphones are quite of good quality or the way sound is routed via USB type C port. Or maybe I'm just deaf and can't hear any hissing noise. Or maybe I'm just lucky and my unit doesn't have such problem. I've tried other headphones with 3.5 mm jack and don't really notice much/any hissing too.
It has a 3.5 mm port then why do you want c type

Theres a hissing sound due to amplifier connected to 3.5 mm jack. That's why.
And if there's option to use type-c earphones why wouldn't you. It's a NEW thing so some users want to try it.

I don't have any hissing sound..iam still on nougat n i use celebrat c3 headphones
I bought this one few days ago and it totally doesn't work, oh and the vid I posted, his type C headphone doesnt work right?
Or probably the converter broke? I don't have other USB-C phone beside me unfortunately.
Got hissing on Sony Mh1c, Kz Zst, Rock Zircon and my Sony MDR 1A.
It's even Oreo.
Xiaomi has Type C earphones, anybody tried them?

I got rid of the hissing sound by using an impedance adapter. I bought the Ifi Ear Buddy. It’s a little expensive unfortunately but it works.
If you rely on system equalizer, bass boost etc be careful, it won't work for USB audio.
I found something
But how can I upload ss there
However, in the developer options, We can select USB configuration.
One of them is audio source. What is this?
Mi ANC Type-C work with media but no calls
I'm using Mi ANC Type-C with Mi A1. The media playback works just fine, quality is good.
Calling is a problem. It was fine before it reset but now the phone freezes if I call with those Type-C headsets plugged in.

Did you manage to get the Xiaomi adapter working with the Mi A1? I have the same one here and it doesn't seem to work out of the box at all.

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
