my case is a little bit different. The noise comes and goes, right channel loud and left indiscernible.
Noise persists when no song is played.

Good luck all hope it gets figured out and nailed down .
 Wonder if a resistor is bad or something.
Tiny cold solder joint somewhere?
 
Would hi-res pictures help for zooming in I wonder?

The player worked perfectly for 20 hours or so in both normal model and USB mode.I checked the board for any impurities,but was none.Something creates that hiss,need to figure out what exactly.

Remove microSD - does the noise persist in DAC mode?

I recently had the same problem with a cheap chinese DAC. I was burning it and after a few hours, without even touch the DAC, an annoying white noise covered almost completely all the sound, so no way it was a bad soldering. I had to return it.
The stock zishan has some sound glitches from time to time but not too often -at least mine-. Now I am waiting for the upgraded zishan and I want to be positive and think it will be ok because I really like this player -zishan and walnut and I don't even think in any other dap's right biw-

I removed the microSD and tried in DAC mode.. Very bad static noise that increases while turning the volume out. I will see what seller has to say to have this problem fixed when he will replay-if he will now!

Could be a longshot but, you could try downgrading the firmware.

I did downgrade the firmware and nothing has changed. Will open it again tomorrow probably and have another go and see if I can fix it before I put it in the bin.
Dang, if you are gonna actually throw it in the garbage, maybe put it in a box and ship it here?
