Bought new speakers but chirping noise is back.

Card is here.

Installed it and there's 0% noise using optical or 3.5mm jack

Assuming all is going well.

I thought to add a note your speakers will respond to a heavy dose of music focused on the mid-range. The highs and lows leak outwards from this base ability to reproduce voices and instruments without strain. Hammering away with chiptune or hardcore D&B will ultimately sound better if you've given the speakers time to settle in.

Oh the interest is there, but the money isn't haha

I'm sure the world of audio is far more complex than just "this cable goes here". I wanted these speakers to add some music to my otherwise silent dancing workout.

My second recommendation is to make sure your speakers are located at the correct height in relationship to your ears. Especially critical for nearfield listening.

Your interest level might also find low cost improvement through vibration isolation. Experiment with what you have at hand or can easily be trialed. Stability of your desk would be your first point to assure better sound is possible. From there your thoughts might find healthy improvement though understanding what raises the speaker height can be less important than what that object sits on. Adding a few pounds of weight on top of the satellite speakers is also potentially going to be a good thing (not if it will fall off - ever).

If your sub containing the amplifier is located on the floor a 12" marble floor tile is a great low cost platform to place it on. Dense wood cutting boards or blocks are a very common solution for satellite speakers. Fiberboard 'speaker stands' and majority of everything else available at retail lack nearly every benefit those two changes will bring.
