Hello I am using DDK sample driver [MSVAD\AC3] for achieving ac3 over SPDIF. But my miniport driver gets a PCM streams converted from AC3 always. The sample driver uses a wavecyclic port with AC3 pins. Its topology filter does not have any AC3 pins\nodes (Microsoft document also recommend like this). Any way to get AC3 pass through with this driver? Should I additionally use any AC3 filter with SPDIF passthrough option to achieve this? Anybody could give a solution please? Thanks and Regards Vargheese ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.com/
