Am facing a strange problem on my treo 755p - the speaker/mic have stopped working suddenly and I can neither hear the other caller nor can they hear me. If I use handsfree (WIRED) then things work properly. Surprisingly, Bluetooth headset doesn't work. After some trial & error I've found that there's an option in Volume Care called 'bypass headset jack'. If I select this option then the phone works for around 2-3 seconds i.e. if I call someone I can hear the first 1-2 rings and then it stops working. The option for speakerphone also only appears for 2-3 seconds and then disappers. Even if I select it after making a call, it disappers after 2-3 seconds. Also with volume care bypass headset jack option I can hear any music i play (continously - not just 2-3 seconds) however, without this option enabled even music sound doesn't come out of the speaker, although ringtones can be heard. I have tried restoring old images through nvbackup, but the problem is still there even if I use an image without any apps etc. i.e. the original image when I had got the palm. Incidentally, this had happened 3-4 months back also, but it got fixed after a few hours on its own. No such luck this time, its been 2 days and the problem still continues. Does anyone have any idea what could be wrong ? Has anyone else faced such a problem ?
