USB Audio not working?

[Mowe1983]

Hi guys!

I haven't found any thread on this topic, excuse me if there is one after all!

So, I bought a P2 two days ago and am very very happy with it! My only problem at the moment is, that it seems to not deliver usb audio. When I plug in my Fiio E07k DAC, It will charge through the phone but the phone won't output music. I tried it with Neutron and USB Audio Player pro. With my Nexus 6 before that, I just plugged in the AMP and everything worked. I could even define an app starting when the Fiio was detected.

WIth the Lenovo it doesn't work at all. I tried it with the cables I normally use and also with the supplied USB OTG adapter. No luck.

Please help! I'm locken and unrooted on Stock Nougat 7.0

Cheers,

Today, I got a replacement unit from amazon. USB Audio isn't working either. Also it was much worse build wise, so I will stick with my first unit for now.

Could somebody check, if usb audio works with a custom rom and is just a problem of the official rom?

Update.

In the Lenovo forum, I got the answer from a Motorola tech agent, that a USB Headset worked great for them through the bundled OTG Adapter.

Is somebody here, who can verify this? I haven't got an USB Headsets.

And maybe there is somebody who has a USB DAC of any kind at their disposal and would try it out... That would be very much appreciated!

Hi Guys!

Here is an update!

Today I was in a local HiFi store which is the only one in Hamburg to sell Fiio equipment, I know of.

I tried out different USB DACs on my Lenovo P2. An Audioquest Dragonfly red, an Oppo HA-2SE, Chord Mojo and a second USB Stick kind of DAC I can't remember the name.

The two USB Stick DAC worked flawlessly right from the plug in! Perfect!
The Oppo was recognized and charged but I could get any music routed through it and the Chord Mojo did the same as my fiio, nothing.

So I summary, USB audio works in the Lenovo P2 but only with certain devices. The drivers seem to be modified from the stock google drivers in this regard.

Hope, the update helps some people!
