Issue with the 2D Viewer Audio Playback

[Dying-Ducks]

Describe the bug

I have TeamSpeak recordings for the demos in .wav format.
Since my demo file doesn’t contain any player communication, I can’t let the .wav file be generated for me.

When clicking on "choose audio file..." I get the vague response "An error occurred." and nothing happens.

When I rename my .wav file to the demo name and put it in the same folder I get the error message "An error occurred while loading the audio file found for this match. Make sure the file is a valid audio file."

So I double checked my file is legit and it’s in the .wav format and I can play this file with the Windows Media player for example. For all I know its “legit”.

In the documentation I couldn’t find anything to this issue.
I tried also multiple demos with their recordings, and the results are the same.
I also tried the audo file formats .mp3 .flac and .ogg, but the results were the same.

Are there any more requirements for the audio file to be classified as "valid"?

Sidenote: When clicking on "Generate audio file" anyways the program will generate a .wav which is obviously silent, but also twice the size of the demo (while my recording is roughly the size of the demo) .
But clicking on the "Audio button in the playback bar" reveals the program still claims "no audio file was found for this demo" after it generated a silent .wav file.

Steps to reproduce

Generate a .wav file of your team communication with Audacity, I merge the single voices from every player (generated by TeamsSpeak) into one .wav file.

Try to use the 2D Viewer Audio Playback feature.

Expected behavior

I would expect that my .wav files work, or at least to get an error message that describes how to fix it.

How often does this bug happen?

Every time

Please upload the audio file and the demo.

Sorry, I didnt mean to close it. I couldn't upload the ZIP file here and accidentally clicked on ‘Close’.

Here you can download one of the demo files with the associated recording from google drive.

I beg your pardon, it should work now.

Could you upload the app logs file?
I tried your demo + wav file and it works fine for me.

[Dying-Ducks]

csdm.log

[Dying-Ducks]

That was my log, but it seemed full of unimportant thing. So i cleared the log now and retried both "choose audio file..." and the "name the .wav as the demo file" approaches.
This resulted in this log:

csdm.log

The logs are not really helpful here, the next version will log more details.

Could you try with v3.15.0 please?
