Hi Mahol90,

      I don't have a ux1 but do you mean that the input meter on the top left in pod farm is not showing anything when you plug a guitar or mic in? When I have lost sound, it seems to be that something has messed things up but it comes back if I pull out the usb and re-connect or possibly restart pc too. You have done this though   Did your ux1 work anytime before?

I don't know all the tests you have tried but have you disconnected other usb cables/devices and tried it in different sockets? You probably have, so forgive me. The other day my ux2 went off when I connected an external hard drive to a usb socket one the pc. I tried this again later and it had no effect so maybe sometimes things conflict and other times they don't.

Have you just updated to 2.51? Sorry. I didn't realise until just then that you were using 2.51. I have kept mine at 2.50 just now as I am in the middle of recording something so I will wait until I have finished. I have seen the problems people have unfortunately had with the newer version. I have noticed someone else on here having trouble with their ux1 on Windows 7 64 bit. I don't know if there is a problem with it with win 7 64 or not, but I think it must be able to because the document for win 7 just talks about devices as if it is meaning ux1 ux2 and so on.

Again, I am sure this is probably a document you have been referring to but I'll link it just in case:

Hopefully someone will know more than me about this problem.

When you run the newest version of Monkey to you have green ticks for drivers/firmware?

Are you speakers/headphones connected directly to the UX2?

Here is a helpful video just make sure you are hooked up correctly.
