Dear problem solvers! Here's a thing: I have a pretty clean windows 7 ultimate installation. It works great, but I have 1 thing thats weird, and looks like a glitch. When I set the audio (rightbottom icon near clock) on "Mute", my audio is muted. When I then restart my laptop the sounds are heared, like the startup tune, and the icon shows a red cross. The laptop is no longer muted and the icon shows a weird red cross through it, as if the audiosomething (card/controller) is deactivated or something? But audio plays fine!! Normally when muting a laptop, after a restart the setting would still be muted. What could be the problem or is it a Win7 glitch? PS: after the restart and I click the, what should be the muted icon, but now shows a red cross through it, it shows the volume is fully open (100%). The only way the red cross dissapears is when I click 'Mute' (the icon shows a red circle with red diagonal) and click 'de-Mute', the icon shows a normal speaker again... Weird huh! So anybody has a solution for this to work properly again? PS: there is a 3rd party software installed, I had to install it, it came with the Realtek AC '97 audio drivers. It's one of those buildin audiochips on the motherboard by Intel. The laptop is a Acer Aspire 3613WLMi. But I don't think it has anything to do with these drivers/software, cause I have been playing with them a bit, and it didn't change a thing to the problem... Regards! P.
