Dear Khadas and community,
I’ve used the Khadas with much pleasure for my Windows 10 setup connected to my studio monitors but since I upgraded to a new machine AND updated Windows 10 from 1809 to 1903 it started stuttering, crackling and popping.
I’ve checked DPC latency issues and my machine had some which were audible but I’ve managed to solve them.
What’s left is every time the audio get’s send through, it will plop crackle at the start of every sound. Even when just pressing Test in advanced device options. It will smoothen out when setting the sample rate to 32-bit 384Khz but some applications won’t accept it and I don’t want to let windows upsample everything and ruin the source audio.
I’ve tried both USB Audio 2.0 driver and Theyscon 224V from the website. It seems to be more severe with the Microsoft driver (Theyscon) than the dedicated Theyscon driver. But present in both. The drivers desperately need to be updated since other manufacturers already got to it with for example the latest Realtek drivers and an Windows update problems for onboard Realtek chips is mostly solved.
My Topping DX3 Pro also works flawlessly with standard Microsoft driver the Khadas should also be able to.
I’m hoping we can figure out how to solve this. Maybe a firmware upgrade is necessary. Other users have also reported issues with the Khadas. I’m curious if more will show up and how common the issue is.
