I am experiencing a problem with my HTC One X. It's only a couple of hours old but unfortunately it's letting me down a bit. It was just laying on the table when somebody phoned me. I noticed that it only vibrated. I checked the settings and all seemed well concerning audio settings but none of the audio was working anymore. First I rebooted, it didn't help. After a factory reset the sound was working again so relieved I started installing apps again and updating again. After the updates the sound was still working. Sadly, the problem occurred soon after again.
It seems that it happens mostly when it comes out of the standby-mode (when the screen is turned off). Sometimes pressing the screen-off button a few times causes the sound to work again and sometimes it starts working again on its own...very frustrating. I did not do anything strange with it and it's currently updated to 1.29.401.11
I think I will return it to the shop but maybe somebody here has a clue? It seems to be a software issue or maybe I am mistaken?
Many thanks in advance for any advice..
