@Mark Sound now works (HDMI and audio jack) on recent images with a newer kernel. Apparmor can be made to work by making some kernel changes (copied from similar changes made for the Pinephone) but this is not yet in the downloadable image.
@Flohack If you don't know there is not much chance of me knowing 🙂 I knew my way around programing (machine code) the old Sinclair ZX81 but other than maintaining a basic website or two over the years and keeping our linux computers at home updated and working I've let that side of my knowledge get very rusty in the intervening 35+ years. I really appreciate the effort you folks are putting into maintaining and developing this OS. I use my phone daily and hope, when it finally gets too old, that there will be a good open source OS to run on my next one. Preferably UBPorts.
