Channel Mixer (foo_channel_mixer)

How about a matrix like in AC3-filter? Maybe in next generation of plugin...next two problems I experience with channel mixer 0.9.4 + foobar 0.9. Soundcard is a Soundblaster Live 5.1 Platinum, kX Audio Driver 3538j a) when I choose 6channel in general tab everything works fine. But when I choose 5 channels center-option does not work, center is always off a) This seems to be a "normal behaviour, but buggy interface" case. I think 5 channel mode is intended for 4.1 speaker setups, so there would be no point in sending a center speaker signal, as there is no center speaker. However, assuming this premise is correct, the wrong option is greyed out when selecting 5 channel mode. While the center option is still switchable (but has no effect), the LFE option is disabled. @skipyrich: Please correct me if I'm wrong. You're right in case of foobar2000 0.9. In 0.8.3 5-channel mode output is L/R/C/LFE/RL. I never tested this mode before... In other hand, in 5-channel sample sent by Borisz channel configuration is L/R/C/RL/RR. Has anyone have another samples or specs?b) 6channel choosed, but e.g. front-speakers disabled. Then choosing "copy" in upmix-tab: Frontspeakers start playing! b) When upmix is in "Copy" mode, there are some strange results when experimenting with the channels. For example, switching both left channels off has no effect in 5 or 6 channel mode, whereas with 4 channel mode the left side is muted correctly. In fact, in 5 or 6 channel mode it doesn't even matter at all which channels are switched on or off, with the exception of the LFE. However, when in "Surround" mode, correct upmix results are achieved with every channel configuration. Channel switching also works perfectly with original 5.1 sources, no matter if it's downmixed (for 2 channel mode) or not. Will be fixed soon. 2Infernus 2Silversight : Thank you for your reports.
