Hello:
So, ordered the cubilux adaptor, plugged it on de dell G3 running windows 10 and..... got the very same error message, tried in other laptop, an HP running WIN11, on that one, the error does not appears but there is no audio signal, changed sample rates, tried other USB ports, both computers recognized the adaptor, so, the next test.
lets try the good old desktop PC running Win XP, no internet conection, jut has Audacity, plugged the cubilux to the USB port, Win XP recognized it, nothing to download and.......there you go! worked perfectly, flawless signal, right speed, I didnt moved anything, nothing, not even sample rates.
My next test is with a 12 year old Samsung laptop running Linux mint
I´ll keep you posted
