I am conflating two issues (the 2.02 patch with patcher, and the one I am really trying to solve, inaudible sound levels).
To dispense with the first, the 2.02 patch run from patcher seems to never finish. I am never prompted to reboot. I may not be patient enough. I'd suggest adding a progress bar to the patcher. As the 2.02 release notes show no mention of sound (my real issue), I have not run it by hand yet.
The problem I can make no headway with:
On a stock PBP running a vanilla Twister OS 2.01 from sd card (Manjaro on emmc), I have nigh inaudible sound. The snd modules and pulse appear to be in order, but the audio levels lack energy: sound is there, but as a practical matter, one cannot hear it. Manjaro has audible sound.
This dmesg is the only sound related error I can find:
rockchip-i2s ff890000.i2s: ASoC: error at snd_soc_dai_set_sysclk on ff890000.i2s: -22
and there are repeated instances of:

Twister is a remarkable product. Running the proprietary u-blox u-center.exe GNSS management tool was seamless out of the box. It makes the PBP+Twister an ideal field tool for cm level GNSS RTK surveying. The combination of these technologies brings the cost of RTK surveying down to c.$1500, typically that costs $20K+. Thanks!
