Sound line in vista

That seems to be the end of the topology for the Speakers endpoint. I'm just not sure where to go from here. Or could that part have been left out somehow by the driver or something?

I really appreciate your input on this. What's connected to the subwoofer part? All endpoints currently have a single connector, which connects to the render pin on the audio topology. That part should then have connectors to the various volume control parts. The volume and mute controls aren't on the endpoint itself, but rather on the controller that the endpoint is plugged into. You can jump from the endpoint topology to the controller topology using IDeviceTopology::GetConnector 0, The sample also describes in general how to go about parsing the topology of the controller but it gets a little light on details at that point, so let me know if you get stuck.

BTW, I'm sure you're aware that a lot of hardware more and more each day doesn't have the "capture monitoring" feature that you are trying to use, so you code should be robust in that regard. I was able to find the controls, but they were really buried. The Speakers endpoint does have a single connector. I obtain the connector and call GetConnectedTo to obtain a second connector.

This is the part you say "should then have connectors to the various volume control parts". IPart doesn't seem to have functions to retrieve associated connectors. Thank you so much for all of your help. I'll check that out -- maybe there is a more straightforward way to access the controls than the one I found above. Unfortunately, there isn't likely to be an easier mechanism. That's actually the way the controls are laid out internally on the audio adapter, device topology just provides a "convenient" way of addressing them.

And are you able to control there volume programmetically??? I think the topology you see when enumerating the parts with EnumPartsIncoming is determined by the sound device's driver. I did not see a part named "Enable Digital Output", but if you call EnumPartsIncoming on that part, and subsequently make the call on any parts that yields, you may eventually get to the part that you want to control.

Provided you started from the Speakers audio endpoint, you should be able to effect the volumes as they are heard through the speakers by calling Activate on the desired part using a refiid of IAudioVolumeLevel. If this call succeeds, you can use the IAudioVolumeLevel functions to change the volume. Ask a question. Quick access.

The A. Because no yard is the same, the Hi-Fi system is scalable, so you can create the best sound experience for your customers' needs. The speakers, in-ground subwoofer and optional expansion satellite speakers work in coordination to create quality audio. Use only Sound by Vista satellite speakers for this system.

Other brands of speakers are not the correct impedance and could easily damage the audio equipment. Prior to digging, mark the exact locations for each speaker according to the recommended spacing in the installation manual.
