My computer includes an HDMI output port on an ADD2 card. The card is
internally connected to the High Definition Audio Device header on the main
board to provide audio output via the HDMI jack. The computer also has
typical 7.1 audio output via ST jacks and an SPDIF jack. The only way I've
found to switch among the audio output devices is to use Control Panel -
Sound - Manage Audio Devices. After setting HDMI Device, Speakers, or SPDIF
as the Default playback device, I have to close the applet and restart any
audio applications before the output is switched to the selected device.
This is really cumbersome and inconvenient.
Is there a way to open the Manage Audio Devices applet directly (without
having to go through Control Panel) to make this selection more convenient?
Also, audio is only output to the device selected as the Default device,
rather than all devices simultaneously. Thus, if you have a digital TV with
an HDMI input, but a receiver with only analog inputs, you can't switch
between the TV's speakers and the receiver's speakers without first going
through the procedure to switch the default playback device and restart any
applications. And you can't use both at the same time.
Is there a way to output to all audio devices simultaneously so I can simply
listen to the desired device by controlling its volume?
Thanks in advance for any advice.
