When playing streaming video over the Internet, one can change the audio device in video playback options. However, although supposedly WASAPI is enabled, the volume control in the player still works, suggesting that it's not really in WASAPI mode. The audio stream is compressed WMA, 128 kbits, so is this what it's supposed to be doing?
In other scenarios, such as playing WMA lossless or WAV local audio tracks, the MC volume control is disabled, as one would expect.
Also, if you stop playing the stream, and check Player Options, a different device is selected, the one usually used for local audio playback, compared to what was set up in Video Playback. Is this what is intended? Apparently the audio device in video playback selected is not changed globally.
