  1. 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):

    Code:

  2. did you press A to select the Audio Stream?
    Quote Quote  
  3. Yes. I can select the audio stream (pressing A or Alt+A or right-clicking, whatever) but there's just no sound.

  4. try extracting 2nd file with gmvxtract and open in audacity.. does it play?
    Quote Quote  
  5. 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...

  6. 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).

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

  8. 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.

  9. Yup, that did the trick. Weird.

    Anyway, thanks a lot!
