After Effects audio sped up (general solutions haven't worked)

Okay, so I'm having this issue, where my audio speeds up by 40% for no reason.

I have reset the preview panel, checked the frame rates are the same, and still the audio is sped up even with the 'auto' framerate option in the preview panel selected.

 

I never had this problem on my old laptop but with my PC i open up a new project, place an audio track in there and it sped up. This doesn't happen on premiere pro with a new project so I'm really confused as to what would be different as both were fresh installs today with no audio settings changed. 

 

I'm using a Studio 24c audio interface and all my tracks are rendered at 48kHz which is the sample rate that's set in after effects, PC has 16GB ram, i5 10400F, and an RTX 3070, not sure whether those specs help or what other specs you'd need. But this is causing me a lot of frustration and I don't know what else to try to fix it. The only thing that has changed the audio speed was manually adjusting the framerate setting in the preview panel to 15, despite the default framerate saying it should be 29.97, but as there's no info telling me what the audio file's actual framerate is, my only option is guessing what framerate it's supposed to be, which is inaccurate and seems like a ludicrous and unnecessary workaround.

 

In the screenshot below you can see that the track length should be approx. 4:30, but the waveform shows it ending at 2:15.

Any help would be greatly appreciated.

Audio does not have a framerate even in the video world. The sample rate is calculated from the embedded timebase info and then correlated to real time. As for your issue it might help if you could provide a snippet of your audio via Google Drive or something like that and more info on how you actually create it. Perhaps that's more an issue of your audio programm messing up something?
