I read this a couple of times still not sure exactly what your asking.
You star out talking about PCs, then swich to audio equpitment but not givng and brands or model #.
Sone links to the PC you are looking at would be help full.
Note: If you're asking for technical help, please be sure to include all your system info, including operating system, model number, and any other specifics related to the problem. John
