Phew, finally able to report more stuff. It always said “you already wrote 3 replies” w/o even telling me what I am supposed to do now, in order to actually write more here. Really weird forum, luckily it seems to randomly work again. Anyway…
Re Bluetooth problems:
It seems a2dp SBC actually works fine, ie no distortion, just it still has very low reception range.
The higher quality a2dp SBC-XQ is actually the one that has all the static/crackle problems, not the normal SBC.
As for missing Netflix (widevine), a workaround I’m using is to just use OBS on my x86-64 Linux PC to capture the Netflix-Chromium window (xcomposite) via recording (NOT streaming!), and set OBS “recording” config to: custom ffmpeg → url → udp://theX13sIP:8081
and then run mpv --no-cache udp://@0.0.0.0:8081 on the X13s.
Added an x11vnc --id (the id reported by wmctrl -l) to it to be able to control the netflix window.
Best workaround that seems possible atm? Only drawback is the netflix browser window on the x86 machine has to be in the foreground, maybe due to X11 limitations? dunno. Pretty annoyingly you cannot even issue xset dpms force off to shutdown all monitors meanwhile, as that will interrupt the video stream too, instead you have to turn off all connected monitors manually via their hardware buttons -_-.
Also I noticed that the Spkr left/right settings since some update ceased to exist in the alsamixer. Instead, WSA_RX0 Digital and WSA_RX1 Digital seem like they help?
However, I have a big problem now:
In the alsamixer I was playing around with the settings to find out which other controls are now responsible for volume now that the Spkr-ones are gone, and when I flipped some option back and forth, suddenly all sound output on speakers would cease - forever! Even though I flipped it back. Even though I rebooted! I can only get sound via bluetooth now, what the hell guys?
I tried alsactl init, to no avail.
So please fix it or let me know how I can fix it, this is not cool, lol. I’ve never seen anything like this on any Linux so far.
Last but not least:
Another problem still existing: Discord!
Armcord works, but cannot utilize global hotkeys, so the only way “discord” currently works on X13s is to either use open mic with voice level activation, or keep the Armcord window focused while talking… (this issue applies to all variants of discord-like apps on x13s, including website-discord)
