What does allow passthrough in some app settings mean?
If you have a sound sytem like for instance a sound bar or surround sound you tell the device to allow it to pass through and let the sound system handle the audio.
I don’t think that’s the meaning here but I am open to being wrong. Usually, passthrough is a term used with VPN’s. Specifically, there are some applications like Netflix for example that may not allow you to launch the application with a VPN running. So as an alternative you can create a fork whereby certain applications that won’t work with a VPN (or even a specific VPN) can passthrough and get to your internet provider. Most times this is an easy setup. You might see it referred to as “whitelisting” an app so that the VPN will not attempt to redirect it to an alternative IP Address.
I think that’s probably what you mean.
That’s called tunneling.
Passthrough is a sound setting not an internet setting. The VPN setting you’re referring to is called "split tunneling ". The white listed apps you added then access the net without using the vpn protocols.
If you are using surfshark your explanation is correct.
When surfshark refers to passthrough they refer to it as VPN passthrough(split tunneling). Passthrough used by itself in the AV world is refering to audio and in some instances video.

Unless I’m not understanding the question (I have the same question) she is talking about when you’re watching something on kodi and trying to get subtitles or turn off the voiceover in a foreign language.
My initial thought to the original question was exactly what @TXRon posted right after. Allowing audio passthrough allows for your TV/monitor to defer high quality sound to a receiver to bring high tech surround sound for your system.
(If we are talking VPNs, passthrough/tunneling as mentioned after would be correct)
@Jackie2 to which apps are you referring?
