There are many boards with OE/Yocto Project support. You can get an
idea of them all from the layer index's list of machines which is
showing 22 pages of them! 

https://layers.openembedded.org/layerindex/branch/master/machines/?q=&browse=1

Some have better support than others, we've had the Beagle devices like
the BeaglePlay and earlier devices like the BeagleBone and BeagleBoard
supported as one of our test platforms for a long time. That has basic
support in meta-yocto with beaglebone-yocto and a full BSP from TI as
well. There are others like the various RaspberryPis and may more,
including more experimental ones with RISC-V processors.

It sounds like the audio output might be important to you and however
you plan to interface the buttons to the system so that may be
something to factor in. You might need USB? That might narrow down your
choice. I'd probably try and find a board which holds interest to you
as well.

Cheers,

Richard
