RPI Zero W Audio on PWM pin

[/RaspberryPi]

Hi

I followed the install guide to set up the audio. Step 8 and Step 9.

https://github.com/johnyHV/simpsonstv/

———————————————————-

/boot/config.txt

dtparam=audio=on dtoverlay=audremap,enable_jack,pins_18_19

———————————————————-

/etc/rc.local

raspi-gpio set 18 op dl raspi-gpio set 19 op a5 raspi-gpio set 8 a2 raspi-gpio set 7 a2

Exit 0

———————————————————-

Functionally everything is working. Video plays but Audio is just noise.

If I hook up a mouse,keyboard to the RPI Zero and playback some video via the internet browser on the RPI desktop, should it produce sound coming out of the PWM 19 pin?

The settings above just routes all audio to Pin19 regardless of what is being played?

This is just to help rule out if it might be the RPI Zero itself or specific video app player issue. I don’t know what the root cause of no audio and just noise coming out. Very little experience with Linux.

Thanks
