Loud/Screeching Audio Bug in Premiere 23.4.0

[Taylor28285958on2c]

During playback, I'm sporatically getting an extremely loud screeching/static noise from some clips, even though they've played back normally for weeks.  

Example video is attached.  (TURN VOLUME DOWN BEFORE WATCHING)

My computer volume was set as low as possible so you can imagine how jarring it is when it happens at full volume.  This is reminiscent of the Adobe/Mac blown speaker issue back in 2019.

Troubleshooting -

- It does not happen everytime.  But it will happen playing back in both the timeline and the source monitor.

- The specific audio file that's causing issues currnetly is a 44khz stereo WAV file, so I've tried replacing it with multiple variations (48khz stereo, 48khz mono, AIFF, etc) and no change.  You can see the audio mixer levels show peaking happening only on one audio channel (in this mono version, it's on the empty one but it happened on the stereo version too). 

- I emptied my cache/pek files, no luck.  

- I went to Audio Hardware and turned Default Input to "No Input".  No luck.

Anyone experience anythign like this?  I'm really worried it's going to be blow my speakers - or give me a heart attack, since it's so loud and random.

Hi @Taylor28285958on2c - Hello @MichaelAHagan,

I appreciate your reporting on this issue. I will alert the engineering staff about this bug. If you can furnish a sample project file and at least one piece of media exhibiting the behavior, that would be excellent. I apologize for this problem. Thanks again for reporting.

Cheers,
Kevin

Hi @MichaelAHagan,

Is this issue occurring in the current version of Premiere Pro? Or are you still using Premiere Pro 23.4? If so, update the application and report back.

Thanks,
Kevin

Hi,

Matt from the audio team here.  This appears to be a bug we are working on.  Copy and pasting attributes from a mono file to a stereo file will leave the right channel of the stereo clip with no audio output (no audio Volume effect on the right channel).  And, since there is no proper Volume effect, sometimes, depending on how buffers are built or destroyed, you will hear either silence or repeated buffers buzzing over and over.

A workaround for you, before we can fix the bug and get it into a build, would be: 

right click on the affected clip, select Remove Attributes

Uncheck everything except the “Volume” effects

Press Ok to remove the volume effect.

This will reset the Volume of the clip.  You will need to apply any Volume keyframes or adjustments, but the buzzing will be gone.

Has this issue been fixed? Ran into this today and it's really frustrating.

Hi @whcc,

Are you still seeing this issue in Premiere Pro 24.6? Please let us know.

Thanks,

Kevin

"This appears to be a bug we are working on."  The copy and paste bug has been fixed in recent 23.6 release.  Please let us know if this is still happening.

I'm still getting a loud screeching noise in one of my clips. Have tried removing the attributes, but it didn't help.

Could you get on a video call with me to so I can try and determine what the issue is?
