Question

I'm programming small program to output generated sound.

My sound card is capable of a 48000 or even 192000 sample rate. Its a Realtek ALC883 7.1+2 Channel High Definition Audio, and the specs can be found here.

However, DirectSound's MaxSampleRate has a maximum value of 20000?

I know I can get better than the maximum from my sound card, but how do I configure DirectSound to take advantage of this? When I try the following:

DirectSound ds = new DirectSound(DirectSound.GetDevices().First().DriverGuid);
MessageBox.Show(ds.Capabilities
                  .MaxSecondarySampleRate
                  .ToString(CultureInfo.InvariantCulture));

In message box the number displayed is "20000".

Was it helpful?

Solution

It could be that your sound card is not the first device in the devices list (for example, a video card with a tv outpout would appear in the list). You should look at the DeviceInformation.Description property. Otherwise, maybe a problem with the driver ?
