Yeh, that'll be it. WDM drivers do not support FM, only VXD.I have a feeling somehow windows installed it's own driver again instead of the Yamaha installer cd version despite being directed to the latter.
It's showing as WDM driver and I don't have any of the control panel software stuff that it seems comes with the drivers. Might be the issue? Worth a stab reinstalling it anyways
Something is defo a miss as now wolf3d doesn't detect a card at all and doom has lost its SFX.
Check by going on dxdiag and going on sound. Under type it should say VXD when the correct drivers are installed
