Huawei Mate 9 USB C Audio output not working properly - Huawei Mate 9 Questions & Answers

Hello,
I am using a Fiio K1 dac with my mate 9. And after using my dac, when I unplug it and try to replug it, it doesn´t recognize it. Sometimes it works after waiting a couple of minutes or after a reboot of the device, but a reboot doesn´t always fixes the problem . Hopefully someone can help me.
Thanks in advance.

USB C audio output?

Hi folks, does anyone know if the mate 9 supports audio via USB C at all?

Should probably try a quick search. https://forum.xda-developers.com/mate-9/help/usb-type-c-mate-9-capable-digital-audio-t3552233
Yes it works with the fiio k1, just get a micro usb to type c usb. I got this on ( https://www.amazon.com/Monoprice-Pa...sr=8-2&keywords=micro+usb+to+type+c+monoprice ). Sounds a lot better.
Cheers folks!

Hey, I'm currently having another question...
Does it work OOB or with a 3rd party app ? Can you use apps like Spotify etc...?
I have a problem with my Mate 9 and the fiio k1. Always after I unplug the usb c cable with the k1 and I want to reconnect it, it doesn´t work. It only works if I reboot the device.
looking for Fiio K1 to work with mate 9 pro..anyone with success please reply and tell me the details of quality and performance..will it worth buying?
thanks in advance
Hello guys.
I'm reviving the old thread.
I want to use my Mate 9 as an audio source in my car, connecting it directly to the installed DSP optical input. The goal is to achieve the best audio performance I can get from it. That's why the Bluetooth is not an option.
So, the setup should look like:
"Mate9 - USB C to 3.5mm cable - 3.5mm to optical converter - optical cable -DSP".
The path is long, but I can't figure out there way to do that.
I tried today, but I failed. As a option, I tried the alternative way of using the phone's 3.5 mm audio jack and succeed in playing some music through the DSP, but still, the quality would be better using the USB port.
My questions are:
Can I use the Mate 9 as an USB audio player?
If yes, are there any settings I shall choose in order to make it stream the audio through the USB port, not through its speakers?
Should I use specific player for that?
Please, feel free to share your thought here.

USB DAC

Is there anyone who have tried fiio dac with your Lenovo P2? I have a fiio k1 dac and it doesnt work with my phone but works well with my old samsung j7(2015).Does changing my stock rom help me with this problem?
For me i have managed to get it to work a few times. Reconnecting multiple times and it would work 1 out of every 15-20 times. Very unreliable and I'm afraid i'm damaging the phone in the process.
I just use allcast to stream music to my laptop which then outputs to the dac as a workaround.

Thanks a lot for your reply.I thought this problem was only with my P2. I have tried as you said.Reconnected multiple times and usb audio player pro plays the music at a very loud volume enough to damage the headphone and then all of a sudden the app crashes.Same case with Neutron music player.Poweramp detects the dac and plays song but no sound is heard.I think any custom rom can help me with this problem
P2A42 (hardware p2c72) here same problem only charging Fiio X3 first generation, used to work on OnePlus one and Moto G third generation

I'm using Lenovo P2 unrooted with Stock.
My Fiio E07K didn't work but I could try some others and the Audioquest Dragonfly as well as the Cyrrus Soundkey work like a charm. The Oppo PM-1 didn't work either.
I'm very happy with my new Soundkey...
I'm also using unrooted Lenovo P2 with Stock (P2a42_S224_170725_ROW) .
I confirm that my Fiio Q1 works like a charm...
i havent faced any problem till now regarding the connection...
Stock ROM, FiiO E18 KUNLUN fully works.

3.5mm adapter not working only on my U11

Hi. My adapter hasn't been working for copule of months, or i thought so. My phone charges, connects to PC, and HTC's original headphones are working perfectly in order. My friend has HTC 10 and when i tried to plug my adapter to his phone it worked perfectly. But the weird thing is my adapter not working on my phone. Everything else (charging, connecting to PC) is just fine. What is the problem?
Did it ever work?
You need adapter with built-in DAC in order for it to work on U11.

I had the same problem after the Oreo update. You need to go to the developer settings (if you don't have that find out how to access it (google)). And you have to enable "Disable USB audio routing" and then disable it again. This worked for me (I don't know if I needed to reboot my phone). Good luck:good:

OTG hub doesn't work

Hello guys,
I have a problem with my OP7 pro, I have this OTG hub NOVOO USB C Hub (8-in-1) HDMI 4K,...
Originally bought for the Mate 20 pro, and was working fine except on this OP7 pro (and even without the IpadOS 13). When I connect it to the OP with and SD card it seems not connected at all, even if the OTG mode it's on.
Do you have any solution? What can I do? Other USB c key seems to works fine, anyway.
Thanks

There used to be an option in developer options.
Enable usb host or something on the OnePlus 5 may still be the same.

I found a solution to make the hdmi hub working, these are the steps, you need to follow them in order otherwise it'll not work:
Connect the hdmi cable to the hub and the tv.
Then connect the usb c of the hub to the power source and wait 10 seconds.
Then connect to the phone and wait.
The power source needs to be always connected otherwise the hub doesn't work.

AUN AKEY6S with Android 6.0 no sound on ARC

Hello all!
I currently purchased a video projector AUN Full HD1080P AKEY6S and I am trying to connect it through HDMI to my Denon AVR. When I plug in the HDMI cable, the sound goes off on the build in speakers and normally should be sent to AVR through ARC + HDMI cable -> well, this is not happening. I tried to unplug all the cables and put them back and still nothing. I would like to mention that currently I am using the AVR with ARC functionality on my TV and works , so the problem is not my AVR but my projector. Someone else having the same issue? How can I fix this?
Thanks
