Sound over HDMI doesn’t work

Click the Volume icon in the top-right menu bar. Set the Default Sink to sndhdmi Analog Stereo

HDMI Volume too low

Click the Volume icon in the top-right menu bar. Open Volume Control... Select the Output Devices tab. Under sndhdmi Analog Stereo drag the volume bar to the far right (mine goes up to 153%, 11.0dB)

Time is wrong, shows UTC instead of local time

Time shows wrong even after updating system time from Armbian config as well as sudo dpkg-reconnfigure tzdata. Shows time in UTC instead of local time (UTC +5)

It’s probably the RTC. Set the correct system time with sudo dpkg-reconfigure tzdata and then manually write the time to RTC hwclock -w. Now sudo reboot.
