Read the Rebooting and firmware doc. It is above the file you circled. You need the firmware file and the tool necessary to install the file to your W2
I got it recognized. Appreciate the help!

I notice there’s a rust stain in the 4.4mm jack and it doesn’t seem like it has oxidized the insides yet. Should I be worried about this?

I tried scratching the stain because it didn’t come off with a q-tip and this is the result

cotton bud soaked in a drop С2H5oH ? rub vigorously but gently.
it is a professional method for cleaning printed circuit boards in electronics. if scratched, the "gold plating" will be damaged and, under adverse conditions, rust will begin.
there are still professional cleaners, but I do not recommend non-professionals for use.

You need to go to
https://drive.google.com/drive/u/1/folders/1--wlg4ZLTdNPHNVJMQri53ReK7jZmKRS
it has the latest FW and Windows driver. If you have Windows 10, release 1703 or later, universal UAC 2.0 driver should recognize W2, but you can also install L&P driver if you need ASIO and for some hypothetical better compatibility with HW, it's LuxuryPrecision_setup_WHQL_20210510.exe from the link above
I have followed the instruction. However, it still cannot detect the w2.

Has anyone experienced the same & knowing how to solve it?

Thx

I apologize if this has been addressed in the thread - I tried searching and couldn’t find an answer to my question. I recently sold my Lotoo S2 and am considering either the W2 OG or the 131. One of the uses I’m considering, aside from using it when I’m out and about, is feeding SPDIF into my Mojo 2 to see if there’s a noticeable difference compared to the Mojo‘s USB input. Here’s my question: can anyone confirm that the W2 passes bit perfect audio via its SPDIF output or is the output capped? Is, eg, 24/192 audio downsampled? I don’t have a ton of high-res, but I have enough that I’d like to minimize the amount of processing audio goes through prior to reaching the Mojo.

Edit, in case anyone finds this helpful: I ended up ordering a W2 OG and can confirm it passes 24/192 audio untouched from its SPDIF out.
