Hi, I was wondering if anyone has found a working solution to this problem. I have tried every suggestion mentioned in this thread, and none has resolved the problem for me. I have a Dell E520 desktop with 4GB of installed RAM, and a SB X-fi Extreme Music
sound card (SB0460). I just upgraded to Windows 7 Home Premium (32-bit) from Windows Vista Home Premium (32-bit). It is my belief that the problem lies with Windows 7 and with the sound card drivers. I have 4GB of installed RAM, but system properties only
shows 3GB as useable RAM. 1027MB of RAM is hardware reserved in the resource monitor. It's here where I believe the problem lies. The sound card functions normally every time I reboot the system, but as the physical memory is allocated to other programs and
resources, the sound quality deteriorates to barely audible. My system also came with a SigmaTel HD integrated audio which experiences the same exact problem, and it this that led me to suspect the hardware reserved RAM as the problem, as opposed to the drivers.
Not sure why or what is reserving the RAM for the hardware. I have already tested my RAM with MemTest, and uninstalled and reinstalled the sound card. I have also checked my MSConfig, and the Maximum Memory in Boot Options is not checked, although I have tried
reducing this to 3GB and to 2GB, which does not resolve the problem. If anyone has any new suggestions on how to resolve this, I would greatly appreciate it. Thank for your help in advance.
