No Sound

---

I just got my new HTC one S from ebay (seller says it was a demonstration device but fully functional). I cannot hear any sound. When I am in a phone call (I can hear the sound in the upper speaker where the sensors are but not on the back) and then start Angry Birds for example sound works. but As soon as I hang up it stops working. Phone Call via Speaker also does NOT work Got a broken device?

Anybody knows a solution? Tried reboot and hard reset of course!

This has seemed to pop up a few times now--no reason that I have heard

I would try to to return it--don't know ebay polices though

what do you think? Software or hardware related?

I have 14 days money back but I dont want to got it for 300 bucks...

Is it unlocked? If its not you can just send it to HTC and get it replaced/repaired for free

It doesn't look like hardware problem, because speaker wouldn't work at all, but if it works in the game, then it could be a software glitch. Have you tried to do factory reset on it? You will loose app, but your personal data, photos, videos and so on, shouldn't be deleted, unless you tell the devide to delete user data. If it won't work, you could try to reflash the device's firmware.

as I heard myself its only FRONT speaker wich works, rear speaker doesnt. Will send it in to HTC tomorrow

Same thing happened to me. I noticed that if you wipe the system and reflash the rom it will work again. A factory reset will not fix the problem. But a system reset will. To do a system reset you must install twrp. If you want twrp your phone has to be jailbroken
