Hello,
Newbie question : I have an issue with an XMOS board since I rearranged its setup.
Basically, Foobar (nor JRiver) can't see the unit, because of a driver problem. Uninstalling Foobar and the XMOS driver was unsuccesful.
Still, the USB green led is lit.
Any idea how to make it work again?

Just tried on an old XP laptop, with USB cable plugged in, and got the following message:
"Setup requires that the device is plugged in. Please connect the device you want to install and make sure it is turned on. If your device is currently connected, please unplug and replug it."
Obviously, the issue is hardware...

I2SoverUSB boards quiet clicks
I got board I2SoverUSB boards it works, but there is one unpleasant moment, quiet clicks during playback, especially audible on Hi-res.
I use the card as a USB-to-s/pdif converter .
Checked on different versions of Windows and different computers.
What can you advise?

The request to lay out somewhere firmware is not older than version 3.06.
It is very necessary, in my 3.46 there are occasionally quiet, almost imperceptible clicks.
Thank you.

I want to ask joro what are the advantages in pcm of the new i2soverusb.
I imagine the firmware for the XU208 xmos has been rewritten.
I have already used the XMOS 500 for a long time on my DAC with the PCM1704 with great satisfaction.

The new board looks interesting.
I've still my I2SoverUSB laying around - my frankenstein/cabriolet build was a bit too much "dangerous" for my two babies - and I was really satisfied with it running as NoDAC and powered with a Reflektor-D.
In a "better" future, you think I'll be able to reuse the PS board?

Second day with the rev.III and after some hours of burn in I can say that this new USB board is clearly superior respect to the old one. Music flow is more natural, better focusing, better timbric refinement too, stage larger, deeper and more precise. It's not a night/day difference but in a good rig the difference is really important. I'm using this new board with his adjunctive oscillators board (Crystek) in a two PC system HQplayer based (server + NAA) with a custom BB 1704 DAC. . All is feeded by LPS Belleson based (PC and DAC)Obviously this system can treat only PCM file but now I would to try again my previous idea of DSD direct with only a second order passive filter and an output buffer 2Sk170 Based, leaved for toomany HF noise . In my humble opinion this new board is really effective and it worth to try. Great job!
Have you tried it without the Crystek clocks? The on-board clocks (the new SDA model) are supposed to be really good.
I own yet the Crystek board, it was assembled on the old USB board, and at time the Crystek was certainly superior in the comparative test, so now I'vnt tryed the ndk again.
The oscillator board is this one
Oscillator board - I2S over USB Audio
You must add the cost of both Crystek.
You'll can buy the Crystek in the same site.

Haha, yes Jocko has very strong opinions on the matter, the problem is that mere mortals like me don't have access to anything better that's commercially available. That's why I got the parts for the well tempered master clock (The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator) hoping that it would perform better than the stuff on Mouser.
I have to build a well tempered master clock yet although most of the parts are in my hands for almost two years 😱
I've got rev.III as well but haven't implemented it yet.
Am I lazy or I'm just in a lack of time and/or enthusiasm?
Time will tell...

I cant't perform any measurement, because I'm interested to listen to the music more than technical problems so the only opinion about Crystek oscillators compared with NDK, assembled on the regular USB board, is a comparative listening test. I own three oscillator board with 6 Crystek on board, but each one is better than the regular NDK oscillator at every listening test done. Maybe I was very lucky but it seems to me that Crystek oscillators are good items, no so failing.
