  I haven't actually seen the schematic for the Walnut, but I will be ordering an Amp, soon.
 
If you think it might be power related noise, after running for a while, it's possible that additional filtering on the power rail(s) could help.

You know I think that I'm the only one having this specific problem so I'm guessing that it's an isolated incident.  I hae two more Walnuts on the way so we will see when they get here.

For a trial, see if changing out the two 100uf for something else  affects/helps it.
I did notice it drop to nothing with the Russkie trials, where before with the Audio grade Silmic 100uf's just let it pass right through.
 
Might be worth a shot.

BTW, I'm having trouble using my Walnut as an amp as the output is very distorted and hollow when doing so. It works perfectly fine as a DAP, anyone got some suggestions on what might be wrong?

 

It's not stock, I've rolled op amps in it and have used the Burson V5i most of the time.

Unfortunately I can't remember what sources I've tried with before and after the op amp switch but I'm pretty sure that I've tested the line in somewhere along the line just to see if it worked and that it did, might remember wrong though.

Yes, I've used several different devices with line out and all of them work with other amps.

I've also tried to tighten the 3.5mm line even out connection without it making any difference.

It seems as if my Walnut doesn't like to be used as a amp, too bad as I really like the way it sounds with high impedance headphones and earbuds.....

 
Bummer! I don't know what might be going on there.
 
A while ago I had only done a cursory try at using the 'nut as an amp, so thought that I'd give it another go now. Laptop -> foobar2000 -> zuperdac -> walnut (v5i) to the Sextetts or Nickerfied T50RP's. Cranked up to ear bleeding volumes, and it's sounding great with no distortion. Hmm, giving my C&C BH amp (which I usually use in the above configuration) a run for the money!
 
Anyway, I hope you get it sorted!

^ Just a  total shot in the dark here peter123, but are you using any 4 pole plugs in that arrangement ?
Sometimes they can slightly work but throw everything off like you are hearing.

My nut arrived yesterday. After initial burn in very good rendering of music texture Goldberg's Variations gave me goosebumps!!
As an amp very sensitive to EMI.
Very good pairing with Monk+ and Superlux HD668B

Is your cell phone on and nearby when using the Walnut?

 

[Abdi]

Even touching the walnut makes noise (using as amp, as dap no noise)

 

[Abdi]

After more hours of burn in, noises as amp are gone. In a couple of weeks will be mod time

There's a Aliexpress sale going on right now.
 
I already have one Walnut player and feel like getting another one as a spare. Should I?

I've been waiting almost three months for my CKLewis order. I asked for him to send another one, but I think I might just cancel it altogether. It'll be five months after ordering at that point. I obviously don't recommend him.
 
He shipped it by Singapore Post 4PX, it's possible they don't accept batteries in shipments and it was confiscated?

It seems as if my Sextett's gone missing, it really makes me sad

Thanks for the suggestion but unfortunately that's not the case. I've actually noticed that the light start blinking after a while although it's fixed when I make the connection to the line in so it's probably something wrong with my unit.

I'm seriously thinking of getting another one to use as a dedicated amplifier.....

Yes, that is worthy of sadness no doubt! 
 
The Walnut/V5i combo really does bring the Sextetts to life. I'm always listening to them now that they found the 'nut.

It doesn't take much to get the light blinking again. A little touch of the volume knob does it for me. Have you tried it with the micro sd card removed?

That's not such a crazy idea actually. I also love how long it lasts on a single charge (that's one of the reasons I use the C&C BH amp the most).

I have 2 brand new units to let go.
