I’m experiencing an audio channel bug in Adobe Premiere Pro.

I’m experiencing an audio channel bug in Adobe Premiere Pro, and the same issue also occurs in the Premiere Pro Beta version.

Issue:
When I import a downloaded clip from the Project Panel into an existing sequence, audio only plays from one side/channel. However, when I create a new sequence using the exact same clip, audio works correctly on both sides.

What I checked:

• The source clip is not corrupted

• Audio works properly outside Premiere Pro

• Audio hardware settings are correct

• Channel mapping and sequence settings were checked

• No export/download issue

• Speakers/headphones are functioning correctly

Observation:
The issue only happens in certain existing sequences. Creating a fresh sequence from the same clip temporarily fixes the problem, which suggests a possible sequence audio mapping or internal software bug rather than a media or hardware issue.

Additional Information:

• The same behavior is also present in the Premiere Pro Beta version

• This suggests the issue may be related to the core sequence/audio handling system

Please investigate this issue, as it appears inconsistent and reproducible across both stable and beta builds of Premiere Pro.
