I need some help fixing the audio so it comes out through the HDMI cable. Also how do I reboot?
This worked on Raspberry Pi 4 using noobs 3.2.0 on 8/9/2019
Open a terminal
type: sudo leafpad
In leafpad click 'file' then click 'open' on the drop down menu
now click 'File System'
Double click 'boot'
Find the file 'config.txt' and open it
go down a few lines in 'config.txt' and find '#hdmi_drive=2'
Remove the '#' so it reads 'hdmi_drive=2'
Save changes and exit leafpad
Reboot system and sound should work. It worked for me.
