Videos downloading with incorrect audio track (English dub instead of original Portuguese)

[RegularPerformer]

Your question

Hi,
I'm from Brazil and I've been using Video DownloadHelper on Firefox primarily to download videos in Brazilian Portuguese. However, I've recently encountered a problem: some videos are being downloaded with an English dubbed audio track instead of the original Portuguese audio. It seems the original audio is completely missing in the downloaded file.

Has anyone else experienced this issue?
Is there a way to select the original audio track before downloading, or to fix this behavior?

Any guidance would be appreciated.
Thanks in advance!

Does it also do this to you with version 9.5.0.2? Could you pass the link to the video?

Problem solved, my friend. Thank you.

I replied too soon — I updated from the beta version to the stable one, and the problem still persists.

I am getting the same but my system is in English and I get German dubbing on all Youtube Shorts. I am using the beta version.
