BUG mono channel only when im uploading stereo

[aurinko_5562]

Issue

When uploading a video in Adobe Premiere Pro, it automatically converts the audio to mono, even when all settings are configured for stereo. Despite verifying the sequence settings and export settings as stereo (48,000 Hz, AAC 320 kbps), only one channel is heard and exported.

This issue is unacceptable and directly jeopardizing my job, and I demand a full refund immediately.

Adobe Premiere Pro Version

• Version 25.1.0 (Build 73)

Operating System

• macOS Sonoma 14.3.1

System Info

• MacBook Pro 14-inch, Nov 2023
• Chip: Apple M3 Pro
• Memory (RAM): 18 GB

Steps to Reproduce

1. Import a video file with stereo audio into Premiere Pro.
2. Drag the file into the timeline.
3. Confirm that the sequence settings detect the audio as stereo (48,000 Hz).
4. Play the timeline audio – only one channel is audible.
5. Export using H.264 with stereo AAC audio (320 kbps, 48 kHz).
6. Open the exported file – only one channel is present.

Expected Result

• The audio should play and export in stereo, with both channels audible.

Actual Result

• Premiere Pro forces the audio into mono, playing and exporting only one channel despite all settings indicating stereo.

Hi @aurinko_5562,

Thanks for filing your bug report.  Are you able to send a screenshot of your timeline and audio channel settings?  Sorry for the frustration and thanks for reaching out.  I hope we can help you soon.

@aurinko_5562,

A screenshot of the timeline and audio channel settings would be useful.

> Play the timeline audio – only one channel is audible.

That is the problem; if not solved, it will not export correctly.

In the Project Panel, right-click the clip and click on Media File Properties. What does that show for Audio?

And then the same for the sequence.
