USB-OTG External Soundcard

Hi there iam trying to use my external USB-DAC (Audioquest Dragonfly) over the USB-OTG Connection and so far i atleast achieved somehow to playback tracks using "USB Audio Player Pro Trial & USB Audio Recorder Pro Trial" but iam facing some serious problems while doing so.
If i activate the lockscreen(pressing powerbutton) to turn the display of, i can't reactivate it anymore, it keeps playing the music but the screen doesn't turn on again.
After 1-2 Minutes it reboots itself without asking for the PIN etc...
Anyone else facing those issues, and is there a possibility to use the external Soundcard without third-party apps?
How about the leaked 4.4 build? I heard USB-Audio is fully functional in 4.4 without third-party apps.
Thank you

USB AUDIO DEVICE issues after most recent update N950FXXU3CRE5

I've always used a mini external USB audio amplifier hooked to my headphones as a workaround to get better audio instead of having to root my Galaxy Note 8 and relying on ViPER4Android for that. It's been working great up until I installed the most recent update Samsung update N950FXXU3CRE5.
The OS detects the USB audio amplifier and shows that audio is being routed to it, but the USB audio device is not initialized and there is no audio output from it at all. The only time the USB audio amp actually works is when I use USB Audio Player PRO to initialize the device, then it plays my audio files but only through this app. Outside the app, nothing works. No matter what settings I change, the USB Audio device only works if it's initialized through the USB Audio Player PRO. This was never the case before the most recent Samsung update.
I'm wondering if others are experiencing similar issues and if there is a workaround for it.
Thanks.

The same update broke a few things for me too. A factory reset fixed them all.

Hey there
I am having same issues and same results.
I tried a factory reset, but that didnt do the trick.
I have a S10+ and rescently got a firmware update. After this update , when i boot my Axefx3 (multifx processor) my usb playback is times 2 (double the speed) like toutube videos or audio playback.
Allso the axefx doesnt route the sound to my headphone. The midi out us detected and selected , but no luck.
Did you manage to solve your problem?

music lags while using Maps

In Android Auto, When I'm listening some music from my phone and having G. Maps on the screen, there's always some lags in music when the map's moving (like in an higwith exit road)
I have a rooted Pixel 3 and a Mazda 3 2018 (Android Auto from MZD AIO)
I've seen in developper's options many options about bluetooth, what should be the best parameters?
Thanks!

I see the same thing when using my Chinese dongle on my android head unit. I've played around with developer settings in Android auto and the settings on the dongle and nothing seemed to help. It seems to be something low level in the dongle (in your case the head unit or mod app) that causes this where moving the map seems to overwhelm to the system.
Using the same headunit and phone but instead using Emils' head unit reloaded application I do not get any sound issues, even when running in 720p mode.
It seems like the issue we're seeing is more to do with the Android auto implementation in hardware/software.

Ok, I'll try it and see how it's going. Thanks

External mic on head unit stops working when navigating

I dont know if this is an AA issue or a bug in my new android-powered head unit. The head unit has an external mic mounted on the dash and an internal one that is accessed via a button on the unit.
When I start AA and Maps is running I can use the external mic as per normal but as soon as I get Maps to start navigating, the external mic cuts off and I have to use the internal one.
When I tell Maps to stop navigating the external mic becomes active again.
Has anyone else experienced this behaviour?

You don't mention the make and model of the unit. Is it AA or kanged Android/Chinese origin head unit.

Sorry, its called Atoto S8 Premium Second Gen so Chinese origin running Android 10.

Question Autoplay music

Hi
I have a problem with my new Pixel 7 and my car. When conected won't play music automatically. I have to start manually. Previous mobile did it without any problems. What can I do?

You'll need an external app, Pixels doesn't have autoplay feature.
for example Bluetooth Autoplay Music, Poweramp EQ...

Perhaps it depends on the music app? Spotify will start playing for me automatically when I turn my car on and the phone connects to it's bluetooth.
On a Pixel 7 currently (stock ROM, not rooted).

I finaly installed Bluetooth Connect and Play app. Works fine and is free.
My Pixel is also on stock rom and not rooted.

I believe there is a checkbox in Android auto settings to allow auto start of music.

Of course, it is, bu not working in my case.
