I have recently got a Nokia N78, and I could use the loudspeaker for some time, but suddenly since the past couple of days, I cannot hear if i switch to the loudspeaker. I have tried adjusting the volume and still I cannot hear anything. Any suggestions on how to fix this problem? thanks,

This appears to be common with the 6515. You will either have to get your headphone jack replaced, or you can try what finally worked for me. Insert and remove your headphone jack as many times as necessary to get the internal connector in the jack to work properly.
It took me about a dozen tries, doing it both fast and slowly.
follow instructions to step 8 (with thanks to Anny for posting it) http://www.annystudio.com/misc/ipaq4700/ With the motherboard removed, you will see the back of the speaker pictured in step 10. I seem to recall that the 'official' replacement loudspeaker (17 UKPounds) looked identical to one taken out of an old Nokia mobile telephone I had lying around. I didn't try it - so I don't know if it would work but the DC resistance across the terminals were about the same. The loudspeaker in the hx4700 is notoriously unreliable and can apparently be damaged by some software titles. I recall that HP published a firmware patch some years ago. I have also found that it is easy to miss the stylus receptical in the top of the device and it is possible to inadvertantly jam the stylus into the earphone socket. This can cause damage to the switch contacts in the jack socket that disconnects the loudspeaker when headphones are used giving the false impression that the loudspeaker itself has failed. I checked this with a multimeter before changing the speaker. In my case the contacts were OK but I doubt that I would have been able to repair the switch contacts without some serious soldering iron weilding. A final note. The ribbon connector for the screen is VERY fragile. Be ultra careful when removing it. Hope it helps. Steve
this problem is due to very low volume of your loudspeaker...when u speak, they can hear u, but due to the low volume of the loud speaker, u can't hear them....so this is the solution: increase the volume of the loudspeaker, by increasing the volume keys at the side of the phone..
NOTE: you should do this when you are in a call....plz be particular in it or the volume won't increase...
