Hi! I have a problem with the audio on my Sony VGN-cs108e model: pcg-3c3l. This laptop came with vista x86, i upgraded it to windows 7 x64 and i noticed that i had no sound coming from the speakers. The volume icon looks fine and when i check the playback devices i see the speakers there. I click test and i see the green level thingy go up as if it was playing something but no sound comes out of my speakers. I found a realtek x64 driver in the sonny website for the VGN-cs108e model and i installed it. Nothing changed, i still get no sound from my speakers. I tried installing win7 x86 and sound works with the default driver windows installed and if i install the x86 realtek driver it works too. I installed ubuntu 12.04x64 to check and see if it was exclusively a x64 problem and sound works very well in ubuntu x64. I have no idea what's wrong and i need some help with this problem. thanks in advance guys.
