Local Display on HDMI0 and sound on HDMI1 on RPI4 ?

[Tim Curtis]

It's prolly doable but I don't have any mini-HDMI to HDMI cables so it will be up to someone else with the cables, a monitor, an audio device with HDMI input, and some Linux experience to work out the configuration so it can be coded into moOde.

My Pi-4 only lists a single HDMI port...

Code:

pi@rp2:~ $ cat  /proc/asound/cards
0 [b1             ]: bcm2835_hdmi - bcm2835 HDMI 1
                     bcm2835 HDMI 1
1 [Headphones     ]: bcm2835_headphonbcm2835 Headphones - bcm2835 Headphones
                     bcm2835 Headphones
