#225 Stereo upmixing not working

[Felix]

Hello.
I've got a 5.1 soundsystem connected to my PC. Everything is working fine, but I wanted to get stereo sound to all speakers. With the following command:

If: inputChannelCount == 2
    Copy: MUP=0.5*L+0.5*R
    Copy: C=MUP
    Copy: SUB=MUP
    Copy: RL=L
    Copy: RR=R
Endif:

My problem is, that it is not working with the If: inputChannelCount == 2. If i delete that, it is working like it should, by only want it to do the upmixing if there is stereo, not if I get the 5.1 directly. What is the problem there?

Thanks in advance

Hi, this problem is for version 1.3.

For solve the problem change " : " for "= " after " If ".

If= inputChannelCount == 2
Copy: MUP=0.5L+0.5R
Copy: C=MUP
Copy: SUB=MUP
Copy: RL=L
Copy: RR=

Your commands are alright but it at least needs a "Stage: pre-mix" command, see example of stage command, so:

Stage: pre-mix
If: inputChannelCount == 2
    Copy: MUP=0.5*L+0.5*R
    Copy: C=MUP
    Copy: RC=MUP
    Copy: SUB=MUP
    Copy: RL=L
    Copy: RR=R
    Copy: SL=L
    Copy: SR=R
EndIf:
Stage: post-mix

Note the last command. It sets Equalizer APo back to post-mix. Note also that sometimes there isn't a pre-mix stage. Besides, the above commands may even not work as Windows/device driver/audio stream isn't reporting the number of channels.
