Expected Behavior

Expecting audio from Media Source (via SRT) to be clean of digital artifacts.

Current Behavior

Expecting audio from Media Source (via SRT) to be clean of digital artifacts. Sounds almost like a sampling conflict issue — constant audio digital bleeps throughout.

Anything else we should know?

The SRT stream is being generated by Haivision's SRT Gateway, which has its source from another OBS instance contributing an SRT stream.

Using the VLC Source with the input SRT stream, there are no digital audio artifacts.

Start by reviewing the linked OBS Studio log and comparing Media Source SRT playback in OBS 27.0.1 with later versions on Windows 10. Reproduce the stream using Haivision's SRT Gateway, then compare it with the VLC Source result. Done means identifying the regression and confirming clean audio without recurring digital artifacts.
