[App_rpt-users] Noisy Quad PCI audio

Hey guys, I am running an 800mhz VIA ITX Board and a quad pci card. The board is 2004 vintage. I have a distinct noise on TX audio both through my node and remote base. I have shielded cables to both remotes, I have replace the power supply and greatly reduced the high pitch noise. An interesting note: the tx audio port is quiet when first booting the node pc. Once asterisk is running the noise returns. Has anyone seen this before? Do I have a bad main board or did I miss something else.. Thanks for your help! 73, Ron - N6GKJ 73, Ron - N6GKJ Sent from Yahoo! Mail on Android
