Ok.. W2 with iPhone 12 Pro Max (iOS 14.6 beta 2) drives my HD800S nicely at 90% volume on the W2 on high gain.. what clipping? Power issue? 🙄

Sorry I wish I could help. I am using windows 7 myself and I have little experience with the windows 10.



Well it does relate to a new hardware - the W2 :wink: . The .sys file is to do with a SATA drive - not applicable in this scenario.

It has not crashed again, so lets see. I am going to try the supplied cable instead of a third party one I'm using.

Finally got some reply from L&P regarding MQA support over W1/W2 - it is impossible to do as L&P has implemented a customized FPGA chip in W1/W2 and MQA will not give out the proprietary source code needed in order to integrate MQA into the customized FPGA.

Similar to my Windows 10 laptop. I don't get a blue screen but the laptop completely locks up and even ctrl/alt/del doesn't respond.

It's 100% the W2. I uninstalled the driver which I installed when I first got the W2. It has been fine since but I've not been using it very often so not sure if my driver was the problem.

Jup I have the same, a massive freeze before the blue screen. Mine comes pre-installed with the updated driver so can't do anything about that. Will play around usage and see if I can find a sweetspot.

What player are you using? I've had lockups with Foobar, Amazon Music and Plex so far. What driver version does your W2 report?

I’ve got 1.0.2.0 - using tidal with exclusive mode. BUT my crashes have happened not in app and not playing. Just connected, idle.

I'm using 10.0.19041.1 and so far so good. I'm plugged in now - will report any further problems if/as they occur.
