Hi:
Check to be sure your mute switch on the top is set properly. If it is you may be experiencing the dreaded "bad headphone jack" problem not uncommon to the 650.
However, when this problem occurs, you usually don't see the speakerphone option displayed.
There are numerous threads about this issue here at ET.
Here is one, and
here is another.
If those aren't enough, try searching the boards using "headphone jack" as your search term.
Some people have had luck using VolumeCare to bypass the problem. I had the problem with my first Treo three years ago and I haven't use a wired headset since....bluetooth only and I haven't had a problem.
Good luck,
SteveTaz

I can only hear some when I use a wired headphone.
What should I do? It is some setting problem? or hardware problem which I need to send to repair? 
However my phone still got alarm sound. |
