I have posted this in the wrong forum i think previously.I have tried updating drivers numerous times without success. i Have two hdd installed in my laptop an Acer Aspire 7520. I tried re installing w7 pro on one hdd but the problem remains.I cannot play/edit my music library because of the problem.On booting sometimes i have sound without any problem but more times than not an x appears on the task bar sound icon.Is this a problem with the bios? I know there appears to be a bios update available but i am reluctant to download it.
