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.

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 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?
