Thank you so much for the help so far it it most kind.

But you forgot to assign second channel. However, I don't believe that this is the problem

Yes I have read through that and this guide builds upon it and is a lot simpler.

yes, first port of call. I don't even get static so this leads me to believe, there is no output of any kind.

Quote:I suppose audremap overlay did not exist when above linked article was written.

So, did you already added

Code:
dtoverlay=audremap

to config.txt without adding dtoverlay=pwm,pin=18,func=2 to that file and use pin 12 and 13 for audio output?

Btw, which sound device are you using in Kodi? You have to use Analogue output

I have it set to both analogue and HDMI which I changed in the main settings.
Tried quite a few variants of code, including what you have said.
This is my current text I added to the config file.

Code:

# uncomment for composite PAL
sdtv_mode=2

dtoverlay=audremap

dtoverlay=audioinjector-wm8731-audio

I need to try building a new filter, I am only testing with a mono quick board that was made up out of salvaged components that I desoldered from old PCB's all parts was tested before making the board up

Finding reference to Kodi, Pi Zero and audio is hard. HDMI and job is done. Not many people want to watch TV on a 2.3" LCD

The model of portable I am using is a small handheld one 'Casio TV-880' It has AV input which is lucky as the old analogue TV signal was switched off in the UK a good few years ago now.

I'll be away next week for Easter but hope to test the new filter before then.
Will report back when I have new findings. Will still check on here if there is anymore ideas.
