Pinebook Pro Initial Impressions

Low volume is an ALSA thing - I had to mess with state file (/var/lib/alsa/asound.state) to make sure all the relevant sound mixer levels are set to the values I want. Run `sudo alsamixer` and see the first two levels - likely one of them is set pretty much to the minimum.

Brightness - I'm not sure what exactly you're trying to describe, I know out of the box some distros don't have brightness keys on the keyboard working properly. There is udev fix for that, though for some reason it doesn't seem to work for me, but the brightness is still adjustable by the slider in my power management applet.

Deep sleep - that AFAIK depends primarily on the interaction of u-boot/ATF with kernel, and it works beautifully on my machine with latest BSP u-boot and xmixahx's 5.8.5 kernel (I've been too lazy to build a newer one). You may be losing sound after waking up, for that see the sound reset script and systemd unit I posted in one of the topics on these forums.

The simple alsa fix is to download this asound.state file https://gitlab.manjaro.org/manjaro-arm/p...ound.state  Copy it to /var/lib/alsa/asound.state Then type "alsactl restore".  The headphone and speaker both require manipulating 2 controls, one works like coarse and the other fine.  The left 2 controls in alsamixer work together.

Wifi has nothing to do with 5G I don't think.  There was a 5 GHz wifi band before 5G came along.  Hefty amount of bandwidth by making all the signals really wide probably.  802.n is wide, 5G may work like that. 5G is 5th generation, after 2G, 3G, LTE, but it's strictly a telephone standard. https://en.wikipedia.org/wiki/5G
