I am having problems with my sound device on my acer aspire 7520 laptop. It tells me that i have no audio output device, this has been happening for a while and then it will come back after doing a system restore or downlaoding the driver again however this time it hasnt worked and i am left with no sound any ideas on how to fix this? Thanx

Boot into your bios and then check onboard periphihals and make sure sound is enabled.
Second while you are trying that please post any new software or drivers that may have been installed prior to original problem showing up.
Third please supply what soundcard you have and what version of driver you have installed

I really dont know what started it off as it was a few months ago now and as i managed to fix it after i didnt think the problem would happen again.

The soundcard is the onboard one which came with it and its a realtek driver v6.0.1.5523 for vista sp1 which i got of the acer support site.

I'll try the bios however as its tempremental i would have thought it wouldnt be this

Went into the bios and there was no settings there to change apart from timr date and boot.

Then lets start with the basic drivers
Realtek Ac97 Ver 4.06

Download The Readme file first so understand everything. Then download the file right above that.This is the newest Ac97.
Install this and then try it. Post back with result

Well I'm happy to see that. I still believe you may have soem type of a virus. If the problem resurfaces please do the steps outlined in post #7. I'm not sure but the symptons are showing a infection since the driver seems to keep going on a walkabout.leave of absence.
Good luck and if you need any more assistance please post and I will help if I can.
