Hello

As post title says. The audio is popping/crackling on playback. Using the same files in windows media player works fine. When playing back via show manager it starts popping/crackling at some parts?

What format does your audio file have? Did you try changing to another format/sample rate/...
What codecs are installed?
QLC+ uses a qt5 implementation for the sound. It might be that QT5 isn't capable of using certain codecs - format + sample rates

Hello

Thanks for getting back. What codecs and sample rates are considered to be in a "safe range". This is an MP3 file. I tried multiple sample rates.

Back again.

Manually reducing and Increase sample rate in MP3 format. This includes 128kbps-192. The audio is crackling popping inside the program. Outside the program the audio is fine.

What gives? Running Windows 10.

I've tried reducing windows volume, reducing the volume in the program. Audio plays fine then results in crackling popping in the same spot every playback.

Solved (Ish): Converting the files to WAV solves the issue for now.

I typically use 44.1kHz. This is the standard sample rate for CDs.

Use a program like MP3Gain to set maximum gain without clipping. This solves the crackling.
