Probably a fried xmos chip, they are very sensitive to ESD, same thing happened to mine.

So there is no saving the d50 now?

edit: sorry for double post, my internet is having an issue

I would double check its not a software issue, the drivers can be funny, but if not spdif should still work

I actually tested this on my sister's laptop that has no prior installation of d50 and is fairly new so I dont think this is software problem. I would try if it will still work on spdif. Unfortunately I dont have an spdif cable so I need to buy a new one in order to test. I just want to confirm that the cable I needed is SPDIF to coaxial? Thanks

There is coaxial and optical, both are spdif, if your source is coaxial you just need an RCA cable to connect to D50 (technically a proper digital coax cable is impedance matched but any RCA should be ok to test), for optical source you need optical cable naturally.
If it works then for best sound I recommend using optical since it sounds best due to galvanic isolation.
Optical is the most jittery digital connection (although I havent seen proof of this.... could be another audio scientist myth) but the ES9038Q2M has asynchronous reclocking designed to 'eliminate' jitter regardless of the source... Im sure it improves optical jitter but of course it is not a perfect world and USB still had the edge in detail/resolution IME.

I will connect it from my motherboard spdif, so spdif to coaxial, is that right?

 

[439598]

As I said coaxial is just a spdif format, if the motherboard is optical spdif or coaxial spdif that is the cable you use, D50 supports both.

Ok thanks, I will give it a try!

Anyone experienced usb not recognized? I have tried different cables but no luck

Hello, Have you changed other PC or change other USB jack on PC?

I have not seen this. You tried different cables and different computers, so you can be fairly certain that the D50 is (at this point) toast.

It is all solid state, but there are lots of ways that solid state things can die. The most common -- in my own experience -- are 1) failed power supplies (if you're running it with a power supply, try swapping that out first, since it's a cheap hack), 2) failed (usually Chinese) capacitors, 3) physical stuff on the electronics (e.g. soda or food that gets inside electronics) that creates a short, and 4) fried silicon (very rare but it happens).

So there is no saving the d50 now?

I would contact the manufacturer and ask them what your options are. It is very unlikely that your issue is user-serviceable (although there are some crazy-advanced users out there).

I am waiting for the spdif I ordered. I will test to see if the d50 would still work using different connection. But on the usb, everything I have tried do not work.

 

[BattousaiX26]

I can confirm that it still works on SPDIF optical, thankfully I can use it before my smsl m400 arrive.

Can you make a screenshot of the device manager and let us know how does it unrecognized. not any hint?
