Hello,
yes i tried. Actually the device i am connecting to is a sound bar. So by default there is no phone audio option. Only media audio.
I end up with the same results with bluetooth audio and casting to the sound bar.
I did try on another device though. Will try in my car this evening.
That problem surfaced for A LOT of devices running Nougat .. Pixel phones had BT audio issues as well as the Oneplus3t. Wish I had a fix for you.

Nope!
However it's my experience that I made a few years ago. My TF300T is a 32 GB version. In 2014 I have been used Cyanogen Mod 12.1 for a short cycle. After the first start of the custom rom I was asking if I wanted to use the recognized external 32 GB SD card either as internal or external storage. Accidently I checked "internal" and couldn't revoke it. After that I realized that the action doesn't make any sens. Unfortunately I couldn't reformat the SD card anymore on my PS because it wasn't readable. It became unusable for ever.
Conclusion: I would never adopt my external SD card to the internal storage, because it plays an important role in case of flashing rom updates or something else.
If you're running windows, you can clear the partition and repartition/format the card using diskpart->select disk->clean (assuming you have a microcard usb adapter)
