[linux-audio-user] ecasound help

[cv223 at comcast.net]

Thanks to Rocco and Eric for the help!  Before Rocco's email, I had worked out the -f:16,2,48000 for the output to get stereo going to -o alsa,default.  However, only the first two input channels were audible.  Looking at the man page, I found that -erm:all,1 -erm:all,2 mixed all the chains to the stereo output.  However, the volumes were weird - the volumes of chains 9 and 10 were much louder than the others.  I saw somewhere on the web that ecasound scales volumes by 1/N when mixing, but it seems that the first two chains are "passing through" at their original volume.  Any pointers on getting the volumes set correctly?

Thanks!

Joel
