A "supermarket" stereo mini cable might magically work for your Uno but I can assure you it did nothing for mine. I have tons of those cables kicking around and tried various ones, but the very loud buzz persisted until I connected the USB isolator which totally silenced it. This device was £5 from ebay and works very well, and I would recommend this to anyone who has a Uno.BONES wrote: ↑Wed Oct 20, 2021 11:37 pmIt's hardly a "special cable", every microphone needs one and, as I said, you can buy 'em from the supermarket or a petrol station, which is about the least "special" thing I can think of. It took me all of two minutes to sort it out with my Uno (because who doesn't have a spare mini stereo cable and headphones adapter lying around?). Since then I have made a more formal arrangement - mini-TRS at one end into a proper XLR at the other but the mini stereo cable worked fine.
Or, and this is by far the easiest fix, put some batteries in it and don't rely on USB. If you've used hardware for any length of time, you get used to having to fix these kinds of problems. They happen all the time.
As to why people suggest using midi cables, wall wart chargers, or even running it on batteries is a mystery to me. I bought the thing to run it on USB, it says it does that on the tin, and thats how I want it to work. What is wrong with expecting something to work the way the maufacturer says it does ?
