Using RSP Pro 2 with Windows 7 32 bit software and it receives very well but I have no audio. Have tried all the known remedies with reloading drivers after scrubbing old drivers, checking known problems like making sure mute is off, etc. I am using Bootcamp on an iMAC core 2 duo (E8135) EMC 2210 with 1 gigabit RAM with version 10.5 snow leopard. Because its an older computer, not much help from Apple help desk. When I reloaded drivers I get "Apple Boot Camp has one or more drivers with known incompatibility with this version of Windows 7. There is a 64 bit chip capability in this older computer but it is listed as a 32 bit version and thats why I loaded Windows 7 32 bit. Question is therefore has anyone found a workable driver under these same operating parameters and if you have can you let me know what it is. SDRuno loads very well on this computer and I can see all the band signals but again no sound.
