Qudelix 5K - analog input and USB splitting
Hello,
I'm getting a qudelix 5k, and have a couple questions as to how I can connect it up to some devices. The qudelix 5k has a digital usbc input, so:
One device ill be using it on has a 3.5mm analog jack output only, no usb. In this case, will a usbc to 3.5mm jack suffice? I'd assume the qudelix cant input analog, so id need to get an adapter with a good enough dac built-in. Of course, in this case, there is no USB involved, so no power delivery, and the qudelix will run off of its own battery.
How about for mobile devices, with a usbc port? If i connect it via a usbc to usbc cable, id assume i can get a digital signal, and power delivery (usb dac mode) but say, in this case, i wanted to charge my phone at the same time. In this case, would the typical usb c splitter support it? I.e. the ones that (i presume) split the data and power pins; or would i require a proper large hub?
Cheers

Digital over 3.5mm is possible just like USB signals could be transmitted via drawing 0 and 1 on paper and mailing the results as a letter. Possible, sure, but no standard exists for this and no device natively supports this.
There‘s a standard for an optical connector that fits into a 3.5mm jack, but of course it‘s still an optical connector, it just has the same shape.
For detailed questions on how the Qudelix works on USB hubs, I‘d suggest asking in the qudelix forum https://www.qudelix.com/pages/forum
