Presumably you are feeding the PC audio out to a external DAC to an audio system.
Based on advice here, I switched from simple headphone audio out jack (using pc's DAC, lousy) to USB audio out to DAC (far better) to Luxman Integrated Amp to Darn good sounding Speakers (more important than the data/dac). World of difference.
I had poor speaker location for many years, totally revised my office for seated ear level, centered seating and could not be happier.

I don’t stream separate audio, just Music Videos, YouTube/Smart TV netflix/prime/viki/paramount .... shows, some here in office, most in Home Theater AV Receiver Downstairs. Most pre-recorded, watch without commercials.
Real Dolby 5.1 sources, OR, turn default pseudo surround i.e. 5.1 off, use 2 channel stereo mode, i.e. DIRECT finds 2 channel original, or forced 2 channel. VERY often better sound.

In the office the PC fan(s) and Hard Drive(s) Noise can be as/more important than the digital audio output performance.
For that reason I buy HP compact PCs with both audio and video on the Intel motherboard, no fans, and Solid State drives (no noise). My PC Processor’s fan rarely comes on, and is whisper quiet. Leave proper/extra ventilation to minimize that fan or any extra fans to run.

Processors are so fast, they have for a long time been waiting for you. Gaming a different world.
