It's work fine 2°) test a windows 7 Pro x64 guest : windows update does not detect the AC97 audio device. I download and install the last Realtek AC97 drivers for W7 x64 from realtek web site. It's work but the sound quality is very very bad. 3°) Upgrade VBOX v3.2.8 to v3.2.10 : same problem on my W7PRO x64 guest 4°) Tests with Audio Soundblaster 16 : not detected by W7 (sound card too old?) 5°) Test the W7 x64 guest on another host with VBOX 3.2.10 : same problem 6°) search for any solution on your site and microsoft web site : no solution Question : What can i Do ? Did you add soon another emulated sound card on VBOX future versions ? Is there a fix (Vbox fix ou Microsoft W7 x64 fix) for this problem ? I had another guest in Win XP SP3 that work fine for months and no problem for sound with this guest so the problem is not a hardware problem ",defect,closed,audio,VirtualBox 3.2.10,fixed,Audio W7 x64 bad sound,,Windows,Windows
