Below I give you the quick and dirty rundown of the setup/routing I use: Keep in mind that Skype does record everything in mono, so you won't hear stereo-music in Skype. This should give you a good clue about your sound and lag beforehand. If you want to make sure all is working well make a testcall with Skype and send some audio and do some talking aswell. I got SAM running stable at 80ms latency running 2 pretty CPU-heavy DSP's for Deck A nd B. Keep also in mind that the latency-setting of SAM (Buffers and Packets) add's to the total lag of the broadcast. In my case a Sound Blaster X-Fi Extreme (very affordable but decent enough soundcard for most podcast/webcast applications) on an AMD Phenom II X4 965 BE 3,4Ghz, 4Gb RAM on Windows 7 Ultimate 圆4 performs decently enough with SAM 4.7.3. You'll need a decent soundcard preferably something that has a good DSP and ASIO-drivers in the likes of M-Audio, Terratec orso. Keep in mind that the more processes you have running in Windows, the higher your latency eventually will be, so kill all those Tune-uppers, Winamp Agents, Bittorrents, etc.
you have to raise the Total Buffer value until the ticking is gone. When you hear ticking in the sound when you are switching between windows, etc. With a dedicated audioprocessor/DSP soundcard you should be able to lower the Total Buffer even more making it almost instant. When I set it up like this I have a lag of about 0,7 seconds which is acceptable imho. You'll have to set it for each Audio Repeater: For all you people experiencing lag with VAC, there is a setting that can reduce your lag greatly. I've done some extensive testing with SAM and Skype and found a pretty much lag-free setup.
