How do I avoid or remove "hollow" sound from captured recording of streaming audio?

My streaming audio is accurately captured but acquired a slight "hollow’ sound in the process.

“audio enhancements” can be on by default, and can add a pseudo-stereo effect which has a hint of reverb. If you are recording the speakers (loopback) any “enhancements” are baked-in to the recording.
