while i use Adobe premiere pro v26 to edit the sound of the video just comes from different channels automatically. i tried to toubleshoot but there is no change in settings. it is a glitch or a bug that premiere pro has in it.

Amy’s right … we would need to see the channel mapping for the sequence, and the audio of your clips as well, to have any clue what is going on in your machine.

Data details are always crucial to helping other users!

Hello ​@visual_Mountainf087 

Welcome to the Premiere forums! We are glad to see you here. We need a few more details to help us understand the issue. Please see, How do I write a bug report?

In this case it could also help us to have a screen shot of your Modify → Audio Channels for the Clips in question and the Sequence Settings. Please note that any changes to the clip in the Project Panel will not update the clip in a sequence. You will have to cut it back into the sequence to get the updated Audio routing.

Thanks for reaching out.

Amy
