That's right analog sound seems available (as shown by /proc/asound/cards) when using  a pine64 5.70 next image with nanopi a64 but no sound ever comes out of the connection, wifi does work.

Here are some of my SBCs that are under $20 (see photo below).  I have divided them into two categories, with hdmi and not. The ones on the left are without, and on the right are with. The ones without are mostly orangepi's and nanopi's. Just do a search on their web sites and if it is under $20, I have it. One thing to consider is the ones with two spi channels (e.g. nanopi core 1 - note core 2 is better but its over $20), this would allow connecting two spi screens. If you connect two relatively big 3.2 ili9341 screens, with the browser stretched across them, your experience would still suffer but it would be okay in some extreme situations. The ones with hdmi include, raspberrypi zero w (double spi), nanopi A64 (double spi), pcduino4 nano (double spi), nanopi m1 - same as pcduino4 nano (double spi), and the other three orangepi's. Bananapi zero is slightly over $20, I have it connected to a lap dock. Of these, the best is pcduino4 nano (get it on ebay between $5 to $16), supported well in software (armbian), and nanopi a64 ($19.99?) is my second choice, software support is getting there (may be?), at least double spi works with pine64 image (latest kernel). Raspberrypi Zero W is only $5 from my local store, and dual spi screen with camera works, you really can't beat it in price.

You could easily do that with any SBC discussed in this forum, e.g. k1plus dual screen + bluetooth keyboard, or a zero plus 2 h5, 5 inch hdmi + bluetooh keyboard, or a pi zero with double 18650 batteries and a 2.4" screen

I must admit I don't really know what to do with my sbc's.  After getting them set up there is nothing more I could think of to use them for.  I guess part of the fun is in getting them set up, and to run them cool during native kernel builds.  Just so it's not a complete waste of money,  I spent more (though not a lot) to add dual screens to some of them. Any ideas what else I could use them for? I already have music players (a lot of them, DACs), NAS, home control, security camera, what else do you use them for? I haven't left any of them outside in the sun yet to try out solar power.
 
So, I added dual screens to these ones (left to right,  counter clockwise) nanopi neo core, bananapi m1 (original banana pi),  pcduino 4 nano (same as nanopi m1), bananapi m2 (a31s),  and raspberry pi 3. All of them have two separate SPI channels, it was fun in making them, getting videos to play in dual screens (though not accelerated, but still ran fine in software), but now what?
 
 

 
Almost forgot, all of them are running Armbian next (except the raspberry) and thanks for the good work here!!!.

You could use alsamixer to increase the volume, the default volume is too low. This is different from the default on the legacy which is close to 100%.
