John,

Thanks for the info.

What OS is on your Aspire and Vaio? And do you let Windows manage the wireless on both laptops, or do you use a 3rd party wireless manager (e.g. Intel PROSet)?

I just found this: http://www.dubflash.com/20/808-Question-Audio-problems-on-VISTA-with-wireless-LAN-activated.html
If this info is correct, It seems Windows is the one to blame...
