Whenever I start the computer, I dont hear any sound from window and if I try to play music from my media player, no sound at all. I can only listen to music or sound via headphone only. I have downloaded different driver on sound and still no sound. HP Pavillion dv6700 Laptop

MP3 players can only play music files in mp3 file format. You can download mp3 music files from the Internet to your computer and then copy them to your MP3 player using the USB cable. For your CD collection, you need to convert your CDs to mp3 music files onto your computer or download them from the Internet and then copy them to your MP3 player after you have connected the USB cable to the MP3 player and the computer.
You can do this using Windows Media player and Rip the CDs - Media Player will create a MP3 music file for each music track. Click on this link for instruction on converting music files to mp3 file format :- http://www.fixya.com/support/r5798418-creating_transferring_mp3_music_files

First Check you have Properly inserted Speaker Jack in right Jack in your computer sound panel. and also make sure that speakers are working perfectly.

if above connection are Ok then Try to play Other Music files in other Music Player like WinAmp, Cyberlink etc... If sound is comming then Install newer version of Windows media Player. other wise there is

install codec pak for the plugins or download "km player" the very effective player

If you connected to a 5.1 surround card and checked and they are connected ok you can hear all the speakers when you play music, movies that are in 5.1 format only. If you want to hear also all of them if you listen to stereo movies/music you must set the sound card to emulate multi channel. Also the player you use to listen music/wath movies must be set to 5.1 and must accept Dolby Digital/ DTS decoding if your sound card doesn't(eg. VLC media player-has integrated DD and DTS decoding and codecs for all tipes/formats).

that message usually means that the audio file is the wrong format for that media player you can download a different player that plays that format, go into my computer and pull up the music files that dont play right click on one and select properties and it will tell you its format/file type

dont know sorry!

Hope this will resolve the issue ....

What is your motherboard type and model? If you purchased your computer a brand new unit,a CD installerforit device drivers shouldcome with it. If you have that Device driver installer CD,try installing from the CD device installer that came with your new PC.

Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware Wizard.

Maybe your headphones are pulled out halfway.
