I bought my UX1 in jan this year and until yesterday, it has been working fine. Now suddenly the phones output is giving extreme noise.I have tried all the steps including running it on other computers, trying different USB ports, trying different speakers and cables etc.
As a matter of fact. The analog outs give perfect sound. So I presume its a problem with phones output jack?
BTW i have made a video of the problem which can be found here.
