I have a simialr problem except that I get sound from the on-board speakers,
(i.e. monitor speakers), but I get nothing from my 6.1 sound system. The
REALTEK AC'97 sound driver seems to be fine as it does the speaker test
correctly, but the Realtek sound manager does not drive the external
speakers. It says it cannot find the 'wave control'. I have an AOPEN "AX4SPE
Max" motherboard. I am thinking I need an updated BIOS driver for Vista but
inquiries to AOPEN have met with no response.
