Nokia DAB Radio on Linux, an interesting challenge

Hi to all!

Here's an interesting challenge that I've been struggling with for a few years now:

Nokia made a small DAB+ Radio USB dongle around 2011.
You would connect it to you Nokia.
Then connect your 3.5mm earphones to the dongle.
(The headphones double as the antenna just as they would for an FM radio)
You would listen to DAB+ Radio via an app on your Nokia.

I have connected one to a Linux computer and Android phone.

The first signs were very promising: sound would play trough the dongle/headphones.
The buttons on the dongle would also function: play, pause, mute, etc. All this with no effort whatsoever!
It would even work on Windows.

However, I could not get the DAB radio to work.
When running "lsusb -v" it is actually detected as "Radio Receiver".

I want to determine the actual DAB chip inside, but I don't know how to do it.
Opening the dongle is easy, but the chip/s are behind a metal shield.
I don't have a hot air station so I can't safely remove the shield.

The benefits of getting it work would be many:
- you get a radio on your phone. (radio coverage is more wide than data coverage.)
- you get a 3.5mm jack for your phones
- you get 7 buttons on the dongle that you could re-assign

This would work on newer USB type-c. All you would have to do is replace the dongle's mini-USB cable with a type-c one.

So where do I go from here? How can I determine what chip is inside?

There are DAB for Android solutions out there, but those are so clunky...

I'm running Manjaro 5.5.6 . I have access to other Linux computers.
