No audio when laptop running on battery (vista)

hello,

i'm having a problem with my sony vaio.
the audio works fine when it's plugged into the mains but when i unplug it from the mains and run it on the battery, the audio stops working.

can anybody help me?
thanks,
ronan

 

Can you expand the "not working"? No system sounds/beeps? Cannot play music? Apps dependent? ...

cheers ...

 

thanks for the reply qhn.
no system sounds, no sound when i'm playing any cd/dvd, when i'm watching videos etc online - completely across the board. all these play fine when i'm plugged in.

 

and you tried with different media players? is it always this way from the start?

cheers ...

 

qhn,

yes, i've tried with different media players and it never works.
the audio worked fine when i bought it first day (nearly a year ago) but i've been having this problem for the past 5 months. when i play some audio online, the levels in my control panel/hardware and sound/sound dialogue box are moving up and down, suggesting that the sound card is working correctly. i know it's tough to diagnose but any help would be appreciated. thanks.

 

You can try:
. check the audio device within device manager and see if it is somehow set to turn off for power saving
. uninstall and re-install the audio device itself

cheers ...

 

qhn,
there's nothing indicating within device manager that it is linked into the power saving options. how do i uninstall/reinstall this device?

 

Control Panel -> System -> Hardware -> Device Manager
. expand the audio, video & game entry
. you should see the audio controller in there
. right click to uninstall, here you can leave windows to automatically detect hardware change and go from there

cheers ...

 

so, just to clarify ... with it automatically reinstall after i uninstall it?

 

It should!

cheers ...

 

qhn,

that seems to have done the trick.
thanks so much, you've been a great help!

i really appreciate it,
ronan
