Usb audio source driver - OnePlus 3T Questions & Answers

I recently bought myself oneplus 3t 3010 and decided to test an audio output from it. So I turned on audio source config and plugged my phone into my win10 pc. And the drivers won't setup properly. What do I do?

[Q] USB Host for USB Audio

Does the HTC Desire 510 have a usb host mode? Virgin Mobile version if it matters. I've been getting conflicting reports ; gsmarena has a small remark in their review that it has usb otg and usb host, but it's not listed as having it in the specs on htc's site.
If it does have usb host is it possible a usb audio device such as a fiio E07K? Trying to find a cheapish but good sounding setup to replace my busted up mp3 player.

Sabre DAC USB Not Detected

Hi all,
Is anyone here using the Sabre DAC on the HTC Memul?
my Sabre DAC Works on my HTC M8 but not on my memul!
its even not show using "lsusb"
i just got the USB-C Version of the Sabre DAC and replaced the
cable with a USB-OTG one, tested on my M8, works but not on the Mini 2.
In one Thread i read that the memul supports USB Audio and someone had success with a different device
but in another thread i also read that the memul wont support it.
so, whats true now? what can i do to get it work?
i'am capable of smd/smt reworking , so if there is a mod on the device itself, let me know.
I also read that there are issues with android 7.1
thx for your help!

Audio out via the USB in car?

Hi
I've received my P20 Pro this week and am loving the phone so far. However, one big issue remains that i can't seem to get my head around - how to play audio from the phone through my non-Bluetooth car stereo?
I previously had an iPhone 6 where this was easy; plug the phone in to the stereo via USB and it would simultaneously charge and play music from the phone through the car stereo.
But when I plug in the P20 Pro via the same USB port, I can't seem to get audio coming out. I know it's possible - as obviously headphones plug in to the same USB-c port - so is there something I have to turn on or toggle to get it to send audio out?
Any help much appreciated. Thanks.

Check you don't have this option enabled in developer options?

Thanks - I looked and it's not checked. In fact, the headphones work when you plug them in, so it is allowing audio out with certain connections.
It's just when I use the charging lead to connect the phone to the car stereo (USB) - nothing happens. It doesn't even charge, and says "check USB" on the front of the stereo. if I play music when it's connected, it just comes out the phone - which obviously it wouldn't do if it was connected to the stereo.
Do I need a specific audio lead, rather than just the basic charging one that comes with it?
Coming from an iPhone background, it's just the same lead... so I'm struggling to see why this won't work either.
My case was huawei p20 pro generate so much noise and jitter during playing through USB audio connect to Helix dsp, it solved by changing USB speed mode from full speed mode to high speed mode on the Helix dsp USB setting. As my iPhone was working fine on both mode. In case if you can try to change setting on your car stereo system. Try to consult with your car stereo manufacturer.
Hi Slangking, did you already find a solution to use P20 (pro) audio over USB in your car? I'm having the same issue as you, went from the iPhone 6 to p20. Just a cheap USB stick works, and I could even remote spotify on my iPhone with my steer trough USB. Changing the USB output in the developer settings to audio source didn't work
- EDITED -
I did some research and mounting your memory card as a USB Mass Storage will work like explained over here, but I still can't find out how this will work for the internal storage...
UPDATE
I found something called WIRELINQ: Smart Android USB Converter Cable for Car Stereo. Started as a kickstarter project, but are now able to buy. Will try that one out.
I got one of these and found I can't get anything to play through the stereo, the audio plays on the phone speakers but the track info displays on the stereo screen and the steering wheel controls also work, I can disable USB audio streaming via the dashlinq app which makes radio player within dashlinq work properly.. but nothing else works.. have you had any luck?
Thanks for your reply. You are a step ahead of me. I have the Wirelinq cable but couldn't get it to work, not even the track info on my cars stereo display. It recognise the Wirelinq cable, but not my phone. I am in contact with GROM and even tried to install a new firmware update (which I was able to install myself by connecting the cable to my computer), so there last message was:
This is issue of the phone USB Audio output in software not working correctly as standardized by Android's AOSP. You will have to contact Huawei to get support and resolve it on phone's software end.

Did you ever get anywhere with this? I'm a new P20 Pro owner (also having switched from iphone 6) and wanting to crack this issue. Thanks.
Not sure if there is a solution. iPhones behave differently when connected to stereos, just like an usb stick. Android devices don't, unfortunately. I am using an AUX cable with the usb-c adapter in my husbands car, or bluetooth streaming in my car.
Bleutooth receiver to AUX

No, it didn't work. Maybe it will if GROM will come out with an update. I've returned my cable and have bought a bluetooth to AUX receiver adapter on eBay for just a few dollar. This actually works very well, you plug the bluetooth adapter in your USB and the cable in your AUX and you can listening wireliss music on each app through bluetooth. The downside is that you won't be able to see your track details, no remote from your steer and the quality is different. But you can still charge you phone with a normal USB cable while listening. It's not a solution, but I got used to it now.
Not a bad idea with the bluetooth to aux!

iphones actually don't behave like a usb stick when connected to a stereo. the music is still played on the iphone, but the sound is streamed to the stereo. controls on the stereo actually control the playback on the iphone itself.
with android, to play audio over usb, you need to use mass storage mode, which will behave just like a usb stick.
ios can output digital audio over it's usb cable, which the stereo can receive.
android can output audio through usb-c, but i don't think that it can be used to output audio over the usb cable like iphones can. it might be some protocol that iphones use and android phones don't, but technically it should be possible.
Just stumbled upon this thread as I am in the same situation. Basically, I have a P20 Pro and a Huawei Mediapad M5 Lite that are behaving exactly the same..i.e they cannot play audio from USB to car stereo's USB ports. The internal media can be browsed and played via car stereos interface but you cannot stream music via USB from phone (say Spotify) to car stereo.
USB audio streaming works if I enabled ANDROID AUTO at the car stereo and installed ANDROID AUTO in the phone/tablet. You might ask why not just settle for this setup?
I can, butI I hate so much the AA's "Swipe to Unlock" lock and the changes in the UI when AA is active.
What I want is the plain/original phone interface (without AA) and all audio routed via USB.
Bluetooth, I know is an option, but again, it would be nice if this (USB) can be solved. It seems possible, I think. If AA can switch USB audio streaming on, can other apps or workaround/reverse engineering not?
BTW, i tried playing with the Developer Options, USB Configuration as "MTP or Audio Source" --- no luck here
Just bought a Kenwood DDX6906S receiver for my 2013 GMC Sierra I cannot get anything to work via USB. USB debugging enabled. I feel like I've been going in circles. any help would be super appreciated, TIA

USB DAC

Hi,is there anybody using USB DAC with Mido? I have dragonfly Black USB DAC.TheDac seems not compatible with mido.I tried on many ROMs: pixel experience, miuipro, resurrection remix.When I connect the DAC thru USB otg, the sound no longer come out from speaker or audio jack,but there's no sound from DAC output either.
This DAC is working fine in my PC, laptop and Xiaomi RN4 Mediatek with stock miui8.
Is there any rom/patch to enable USB DAC on Mido with Oreo to be specific?
Thanks:good:

I tested my SMSL Audio M3 USB DAC with my Snapdragon Note 4 and it worked immediately without doing anything but plugging the cable. I'm using the unofficial Oreo Resurrection Remix by EndLess. Hope you find an solution to your issue. :good:

Razer phone 2 not detecting earphones nor Android auto

I recently got my USB-C port replaced by Razer because it was charging right and it out of nowhere stop syncing to Android auto. Now it charges fine but my car still won't recognize the phone, it will for a sec and then it disconnects. Also when I plug my earphones in, the audio still plays through the speakers, in option pops up to change the USB preference but it won't do it.

One thing is that some USB-C headphones don't have a AMP/DAC built-in. This is a common problem with Razer Phone 2 users, as it doesn't have one inside. So, if your headphone adapter or USB-C headphones don't have one built-in it won't work. 2, seems like Android Auto doesn't like some USB cables. Try some troubleshooting from at the "My Android Auto app isn't working" page on the Android Auto help page.
I was experiencing relatively the same thing. I tried cleaning and tightening the usb-c port on my phone. Didn't help. So I tried cleaning out the usb-c charging cable, the end that plugs into the phone. Problem solved. It works fine now, for the most part. Still will disconnect from Android Auto if I move the phone around to bunch. Or put the cable in a bind near the end that plugs into the phone.

Android auto and the adapter for the earphones used to work fine, it just happened out of nowhere before way before I sent the phone to get fixed like 2 weeks ago, the problems started last year but i think there was an update of some sort. It still won't connect, even when using the original adapter and my pc doesn't even pick up that the phone is even connected, it will just charge. I've already check the device manager to see if it was a bad driver but nothing. no matter what device i connect, it will just say "Charging connected device via USB". ive Already tried USB debugging, disable USB audio routing, cleaning it, and apps to manually control it.
