Output audio quality

During the event I need to play out the audio on a sound mixer, that will drive the theater sound sources.

The PC I'm running HeavyM on has an ASUS Prime B450-Plus mobo with a Realtek ALC887/897 audio codec.

Last year I just used my case (Fractal Design Meshify C) front mini-jack to send audio to the mixer, and there was an horrible hissing sound, so much I needed to lower the volume to the min acceptable for the show.

I tried to purchase an (economic) USB sound card, but this didn't make any difference.

Wanted to ask if there is any suggestion about how to solve/improve this problem: try to get out the audio from the MSI RXT 3070 Gaming X Trio videocard DisplayPort (is possible?), purchase a better USB audio card,  purchase a PCI audio card (i.e. Sound Blaster Z SE?), using audio optical output (if acceptable from the ancient mixer), check the power connectors, or something else.

    Hi

    In audio the quality of the signal is determined by the worst component of the chain.
    That means that you have to check every component yourself including cables, mixers and stuff.
    Unless it turns out to come from HeavyM but it seems unlikely.

    This reminds me of me every larger event trying to use some default soundcard. There is so much noise everywhere, so basically only not hissing source is usually a laptop not connected to mains power. 

    Pro tip is to use optical audio, there's no noise, no hissing, no electric potential, no problem.

    Thanks both, my post was also due I remember reading an article about HeavyM suggested sound cards, but I didnt find it so was probably immaginating it.


    Today I will finally ask to an audio specialized shop for help, deepening the topic I need to connect my PC to a mixer Yamaha LS9 that has also a digital 2TR audio in, but how to reliably connect an optical TOSLINK audio out (from the PC sound card if I purchase it) to an analog RCA jack used in 2TR without transferrimg suprious noise it's not clear at all at least to me, so will ask a professional.

    Just to add following specialists advice I purchased a Motu M2 external audio interface, supposed to solve the probem together with balanced audio cables.

    I will need to test on the theather, but sure not a software problem.
