According to the control panels and DxDiag I have "3" sound devices. 1. SB X-FI Audio 2. Modem #0 Line Playback (emulated) 3. Modem #0 Handset Playback (emulated) Here's the thing. I have no modem. In device manager, No modem. In the Sound Control Panel, there is no modem listed under hardware. This is all it says for hardware: Creative SB X-Fi Audio Codecs Legacy Audio Devices (empty, there are no devices listed) Media Control Devices <------- I have no idea what this is... I think it's midi related. Legacy Video Capture Devices Video Codecs These extra devices are causing other bugs in my system so I need them killed and I don't want to have to reinstall the whole OS to do it. I know that both of those "devices" are connected because if you kill hardware acceleration for one of them it kills hardware acceleration for both of them. So it's the same culprit. At this point, I'm game for anything... reghacks, system tweaks... Anything to make this thing go away. It's driving me crazy.
