Is it possible to change code of "Downmix 5.1 to stereo" DSP in such way, that it would recognize different types of channel masking as 5.1?

As found by lvqcl here: http://www.hydrogenaudio.org/forums/index....st&p=822884 this component properly recognize 5.1 stream when channel mask is "6: FL FR FC LFE BL BR" but doesn't recognize 5.1 when channel mask is set to "6: FL FR FC LFE SL SR". Side channels aren't recognized... Could this be fixed and changed that both channel masks will be properly recognized? And other variants (if exist)?

I think I have to revive this thread. I played 3 DVD-A .iso's. Two of them were just 4 channels recordings, where there were FL, FR, RL and RR channels. Such files aren't recognised by "Downmix 5.1 to stereo" DSP. I know that these 4 channels is 4.0 and not 5.1, but why not allow 4.0 to be downmixed by this DSP? Additionally I found that third iso contained FL, FR, RL, RR and FC channels. That's 5.0. Still not 5.1, but why not just treat 4.0 and 5.0 streams as 5.1 with certain channels just muted?
So here is my feature proposal - allow 4.0 and 5.0 (maybe other) channel configurations to be downmixed by "Downmix 5.1 to stereo" DSP. Missing channels could be treated just as empty/muted streams (zeros).

Try using Channel Mixer or Matrix Mixer in the meantime (or instead).
