You need to go into the settings on the Yahoo chat page.
You can then set your mic and speakers and check that they are now working

without knowing its motherboard or proccessor we cannt troubleshoot this prb show plz ......(if u can installed xp own your own hope u know abt ur pc configuration to)

This can be caused due to one thing. Either the Song or Music you have installed into the Memory is not supported by the Phone or is in a Format which your Phone is not able to read. My advice is to Uninstall such undetected data from the Memory to avoid secondary Problems such as memory failure. It is not just your Problem, It is happening in many phones including the XpressMusic sets and many more.
Thank you Sir, Hope you understand the root of the Problem. Have a nice day.

my LG DVD writer cannt works properly.It writes a blank Disk but cannt read CD or DVDs that are bought with monthly magazines.

If you have onboard sound then open bios setup here u will definitely found the model no. & manufacturer of the motherboard. then noted it and download the drivers for this motherboard.

You will need to go to the manufactures website and install the drivers specific for your pc or sound card. A codec is not what you need, codecs are for decompressing methods for viewing or listening video or music files that used specific methods.

Use "Ctrl+Alt+Delete", choose processes, find the "ITunesHelper" line, and end the process. Then connect your phone with the phone closed. This should connect it as a removable drive.
