I just updated from quay.io/invidious/invidious:latest (2024.11.10-5d2dd40) to quay.io/invidious/invidious:master (2025.01.22-164d764). Audio track switching in 2025.01.22-164d764 works as expected.

In both versions the English audio track is playing by default.

in newpipe, the default track is the original one though

maybe they parse the displayName looking for "original" (I guess, I don't really know)

[syeopite]

Apparently YouTube does provide information on which tracks are dubbed and which are the original variants. It is harder to access though.

Invidious current logic isn't really built for parsing the extra data required to differentiate between original and dubbed tracks in a clean and performant unfortunately.

The fix for this issue will likely have to wait until #3620 is merged
