ok i am surethis has been asked before so please forgive me....i have search intesively for a answer but does any one know why i don't get sound on you tube? if seems a common question but i dont seem to be able to find a common answer
I'd check the audio properties on the pc first. Go to Start, Control Panel, Sounds and Audio Devices. Make sure none of the sources are muted ( volume tab and advanced ).
Next go to the Audio tab and check your sound card is selected as the default playback device. Post back if this does not sort your problem.
Follow these steps:
1) start
2) run
3) regedit
4) hkey_local_machine>software>microsoft>windows NT>CurrentVersion>drivers32 look for wavemapper registry at the bottom and double click it, Add msacm32.drv... if it is not there right click, go to new string value and call it wavemapper and once again add the value msacm32.drv.
