Topping NX4DSD->Thesycon XMOS-USB Driver Skysong/Singxer ES9038Q2M

so, 😉
because i have here really heavy problems in playing anything above 44,1/16bit due to buffer(and/or driver)-problems (on a raspberry the ES9038Q2M works perfectly) on a Skysong (Singxer)-USB-bridge and a ES9038Q2M (“Blue”) i came by chance across this Topping NX4DSD..

it has also a XMOS-XU-208 and a ES9038Q2M “onboard”; interesting is the specification:
“16/32bit 44,1-768khz + DSD512 (native)” and (whats more interesting):
“NX4 DSD use costum driver from Thesycon”..
so, and thats the thing here..the “normal” Singxer USB-Audio Driver 4.36″ does not work here satisfying with a ES9038Q2M..
2 possibilities: we get in future an update for also playing on this ES9038Q2M without problems from Singxer or we can get some custom made Theyscon driver which matches “our” Skysong-Bridge+the ES9038Q2M..(any help here is really appreciated !!)
i´ve anyway attached here (and in the forum) the original Topping NX4DSD driver+manuals, which were btw. very interesting in setting up JRiver for perfect bitstreaming..(u have to use completely the ASIO-driver/interface..))
the Topping NX4DSD driver/manuals is the version V4.14..->NX4 DSD Manual and Driver V4.14->http://essabre-90xx-rpi.sfb2.com/forum/showthread.php?tid=22
