Hi Rob,
Thank you for the answer. I was afraid of that. It is important for me to
perform the downmix myself. Is there a way to accomplish this by for instance
making a LFX instead?
I also find the behaviour suboptimal in some cases. An example of this is when
connecting a PC to a surround receiver using HDMI, in that case you would want
the surround receiver to decide if an upmix should be performed and perform it
if needed. Ideally it should know if the audio material is stereo or true 7.1
surround material. Even though Windows would not upmix the stereo content to
7.1, the surround receiver would not know this as it receives 8 channels (6
containing silence). I realize that it becomes a problem when playing back
multiple audio tracks (both stereo and 7.1) at the same time on a PC but in
that case it should default to the highest common number of channels, 8.
Regards,
/Kim
