LFI Player + DAC problem

[ReNNo]

No, I use the same 12V rail for laser diodes and for opamps.
I'll try to power it independently.

I know that SpiroDAC produces crackling sounds when I adjust sliders, it is normal, but I hear these crackling sounds when I do not touch anything.

EDIT:
Another PSU is added to power up only TL084 that controls galvos. And I can still notice that projected image is moving as I turn on/off lasers. Doesn't it tell me that problem is in sound card?

EDIT2:
Here is another video that shows the problem:



EDIT3:

I made a new kind of test trying to rule out some possible causes.
To eliminate problem with voltage drop I disconnected every laser module from DAC+Analog driver and I used Arctic in order to project an image.

And I found something disturbing. Without blanking image was very still, then I tried 1Hz and 3Hz modulation and projected image started moving.
If this is not cause by voltage drop of op-amp circuitry then it must be problem with sound card. I think that one channel of sound card has influence on other channel. It's my only logical explanation.
Is it possible that sound card is defective? Is it maybe driver related problem? Can someone give me version of drivers that are proven to work with DAC.

Here is video again:

You might have a weak ground connection, try connecting a heavy wire between
the ground side of R Sense and the diode power supply.

I've just eliminated that problem in post above. I disconnected every laser module from this PCB. There is no high current flowing. That means that voltage must be stable. There is nothing to interrupt voltage in "correction amp" circuitry.
