I tried to retest the CMI-Soundcard (IC "HT8738") on the mainboard "Elitegroup P5SSML", knowing that it worked the last time I tested it a few months ago.
ReactOS provides already a "working" (as of device manager) driver for this card, but it does not produce any sound.
For this reason I replace the driver with the one supllied with WinXP. After install of that and reboot the driver crashes when it tries to play the startup sound.
This WinXP driver is attached: [^CMI8738 C3DX PCI Audio Device (NT5).zip]
