Hi all

I am wondering if something is not missing in audio device selection for some communication case.

Regarding to audio device selection, the media capture scenario document (https://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/scenarios.html) talks of the case where the user selects between a microphone device plugged to the audio jack, or the microphone of a webcam. But there is another common case: the user has a microphone in the audio jack and a usb headset (speaker+microphone). To me, in this case:

-          When the user selects the microphone device in the audio jack, he will most likely want to hear the remote party in the speakers of the computer

-          When the user selects the USB headset device, he will most likely want to hear the remote party in the headset

But with some tests based on Chrome 24, the audio is always played through the OS default audio device, even if I select a usb headset as audio capture device (which is of course not the OS default device).
AFAIK, this is explained by the fact that on one hand the media capture API enables the selection of the capture device only. On the other hand, audio HTML tag uses the default rendering device of the system. I could not find any document talking of audio rendering device selection.

Any thought about this? Did I miss something?
