On a pc where xp-sp2 was reinstalled from scratch, Live Messenger works properly except for sound. The person we call can hear us fine but his voice is garbled. When we play a DVD movie on the pc, sound is also garbled. On the other hand, a music cd plays fine (over same player). And when there is sound on PowerPoint (PPS) documents, sound is also okay. The sound device is a built-in Creative SB PCI 128 (Ensoniq ES 5880). We updated the firmware with an upgrade from the SB site: SBPCI128Setupus_w2k. No change. We then tried to install the most recent firmware version WebDrvsV5_12_01. We got an error message telling us we had no Sound Blaster device (!!!) although it's a Creative SB PCI 128 (Ensoniq ES 5880).
