PotPlayer can't play audio in 2nd stream, but Windows Films & TV can

[Acccent]

Hi there,

I was wondering if anyone could help out with this issue. PotPlayer plays the main audio stream from a file, but not the secondary one... the Films & TV app has no issues.

I've downloaded the latest codecs and tried changing the decoder settings, to no avail, but maybe I missed something. Right now everything is back to (Recommended) settings.

Here's the relevant media info (let me know if it's missing something):

did you press A to select the Audio Stream?

[Acccent]

Yes. I can select the audio stream (pressing A or Alt+A or right-clicking, whatever) but there's just no sound.

[teodz1984]

try extracting 2nd file with gmvxtract and open in audacity.. does it play?

[Acccent]

I can extract the file and play it with no issue with the Groove app.
However Audacity doesn't play it as it is AAC which isn't supported in Audacity...

[Acccent]

I tried reinstalling PotPlayer, making sure to select "install additional codec" (didn't work), then tried going into Preferences > Filter Control > Audio Decoder > Built-in Audio Codec Settings and selecting either OpenCodec options for AAC (didn't work either).

Does anyone have an idea on what might be happening and/or how to fix it?

[Dreamer]

Similar topic from the official PotPlayer forum:

https://potplayer.daum.net/forum/viewtopic.php?f=9&t=20716

So try this:

It seems like disabling seamless playback fixed this problem in the original files too.

[Acccent]

Yup, that did the trick. Weird.

Anyway, thanks a lot!
