When i play music, the sound would come out from one speaker only. the audio jack seems to be fine, but do not know what is wrong. my model in logitec LS21

it seems like the output jack of your pc isnt fairing well and does sound like it needs replacement but i cant tell if the speaker wire your connecting to is a desktop or to a laptop but by all means it does sound like the output jack is damaged and need of repair

Hi try looking over it again with the help of this https://www.download.p4c.philips.com/files/s/spa7300_79/spa7300_79_dfu_eng.pdf just make sure all connections are pushed in properly as those plugs have a tendency to not plug in all the way

that means the guy or someone who replace the new harddrive didn't to a good job on restiall a new window vista for you, just simply go acer.com and search your model, redownload the sound card driver.

that's it.................

must be sound card driver problem.

Are you sure that the soundcard supports 5.1 on your laptop?

go into your sound properties and make sure your sub is turned on or not muted there should be a seperate one for sub just like you have one for speakers

go to the control pannel, then go to sounds and audio devices, then click the audio tab across the top. under sound playback, choose your speakers as the default device. solution only works like this for windows xp. good luck

so you are saying that there is no music. ok. you might need to get a new speaker. or there is a bad connection. try plugging head phones into the jack of the psp. if u can hear music just fine then its your speaker or a bad connection. if you still cant hear music. then you need a new sound board.

if ur usung win xp OS U shold restore OS (pgm-accessories-system tool.restore )to back date while it in workinfg fine

First try the headphones in a different machine, such as an mp3 player or cd player to make sure the headphones still work.

Try going to the start button, then settings and control panel. Then select "Sounds and Audio devices" Down at the bottom you should see "Speaker settings." Click the "Advanced" button and then select stereo headphones.

Then, place the headphones into the green audio jack (or the headphone jack up front if you have them), play some music, and then gently wiggle the jack to see if some of the sound makes it into the headphones. If not, try slowly pulling the headphones out of the jack while the music is plaaying. you might find that the jack has slipped a little and may play only if your connector is slightly pulled out or more firmly pushed in. If his helps, then your audio connector is loose and you should replce the sound card. If the card is on the motherboard, you can disabled it when you put a new card in.

Have you tried a different jack? It could be faulty.
