Got my device yesterday and as I don't have an iphone adapter, I am using it connected to the laptop and having some issue with it.
There is crackling sound that is really irritating me. Besides that, when listening to MQA on Tidal sound gets cut off for a split second every minute or so (checked Task Manager, cpu and memory are not too high).
I've tried several different usb ports, both issues are happening. I've also updated firmware to the latest version.

One more thing I've noticed...if the screen is turned on, it keeps jumping between PCM and MQA.

What operating system on computer so you use? If you are on windows 7 you need to be in UAC 1 mode.

Ok, tried it on my desktop machine and both issues are solved.
However, I've bought this to get better SQ from my latop (using Schiit stick with my desktop) :frowning2:.
Then there must be something wrong with your USB ports on the other computer.
Can you uninstall and install again the drivers and see if the problem still persists?

I've reinstalled drivers, same issues.
I've tried 3 different usb ports (2 on my laptop, one one the monitor that is powered up via hub), even tried usb-C - same result.

I get that, I am just trying to figure out what could be causing this...is this a power related issue or maybe a software issue?
It behaves exactly like in the video posted by @Sluggist : https://streamable.com/7os79u .

There is no crackling if I connect the device in UAC1 mode. MQA won't work in that mode.
But I can live with that and only use MQA when I connect it to my desktop or iphone (after I get the adapter).

@waveSounds I've disabled those settings.

@shinbojan Have you tried checking USB setting underneath Settings > Power and Sleep > Additional power settings > Change plan settings:

I don't really see this being the problem, but if the suspend settings is set to enabled it can sometimes cause weird interactions to occur with USB devices. Worth a shot.

Is the latest 1.1.10? I have had the same issue with the .09 version. Further upgrading fixes this.

Is there .09? I've upgraded to 1.0.0.8 and then to 1.0.0.10.
There was no folder for 1.0.0.9, but it was mentioned in the readme file.
When I connect the device, it shows 1.0.0.10 as version.
This is how the archive looks:

Just stopped by to ask if you have managed to find out what was wrong with your S1?
I really like mine.

I think the version 10 is intended to replace version 9. Hmm then this seems to be a real problem. Have you tried a different source (like different PC/tablet)?
