How to Fix the Speakers on a PSP
Update the PSP operating system before doing anything else. Many newer games make use of updates to the PSP system that you can get by download from a Wi-Fi network. Not having the newest files may prevent sound from playing. If you have not updated your PSP's system in more than six months, connect it to the Internet. It will automatically search for updates and install them.
Check that nothing is stuck in the earphone jack. Particularly if you use older headphones to listen to your PSP, small pieces of the input may break off and remain inside the jack, causing the device to think it is feeding sound to earphones. Tap your PSP on a hard surface or gently use a wooden toothpick to check for any loose material.
Insert and remove the headphone jack multiple times. Often, the headphone jack solder connection may be faulty, causing your system to think that headphones are always plugged in. Sometimes, jimmying the connection in this way clears up the problem.
Open the casing if none of the above steps work. Check to see that the wires connecting the speakers to the Wi-Fi wireless/memory stick/sound board are in fact connected. (You can easily identify this board because it houses the memory stick casing.) Replug the wires if they are disconnected.
Replace the speakers. You can purchase new PSP speakers quite cheaply from the Sony PlayStation Web site. Speakers install easily with no soldering required. It would be best to test them on another PSP if you have access to one before buying new speakers, however. This will also help determine if the speakers themselves are the problem.
If new or replacement speakers still do not work, the problem is with the Wi-Fi wireless/memory stick/sound board. You can purchase this from the Sony PlayStation Web site if your PSP is no longer under warranty. Replacing it, however, requires you to take your entire PSP apart, which may cause further problems.
