How to create different audio passthrough profiles based on specified priority and rules?

[spinktvis]

Recently I managed to get HDMI audio passthrough via ARC to work with mpv and pipewire. For anyone interested my current setup is as follows:

Desktop computer with HDMI to the TV -> TV ARC HDMI to the Sound System.

The working mpv config:

ao=pipewire
audio-exclusive=yes
audio-channels=5.1,stereo
audio-spdif=ac3,dts,eac3
af=lavcac3enc
ad-lavc-ac3drc=0
ad-lavc-downmix=no

I would like to know, if the following is possible first of all, and if so, how to create rules/profiles based on manually specified audio track priority?

• For example, if there are multiple multichannel audio tracks available, eg. Dolby TrueHD Atmos, Dolby Digital Plus and Dolby Digital, to let mpv automatically choose the Dolby Digital Plus track and enable passthrough and ignore the other two?

• And when there are multiple multichannel passthrough tracks available, eg. Dolby Digital Plus, DTS and Dolby Digital, to prioritize one track over the other for passthrough and let mpv choose based on a configured list, eg if all these are available choose DTS over the others, or if DTS is not available only then choose Dolby Digital Plus?

• And last but not least, when there is a stereo channel Dolby Digital Plus to let mpv process this audio track first instead of directly passing it through?

Any help is appreciated!

sorry didn't help. I think for automation you could do creating a .lua script then placed into script folder in MPV installation folder. How? maybe you could ask A.I (Copilot or ChatGPT and so on) to make a efficient .lua script for MPV player, then trial and error by yourself because sometimes A.I. coding can getting more worse than human logic.

You could share your script in here. It might useful for someone who've same problem. Or as backup note so you could access everywhere then copy it again.

Thanks for the reply. I'd hoped it be less involved and straightforward like setting audio/subtitles language priority, or a simple conditional profile. I'll keep on fiddling around.
