[LAD] mudita24 summing pct outs

I was playing with alsa arecord and daring to brave a .asoundrc for my delta 1010. I set up a multi-out and monitor mix to grab the digital mixer output [1] pcm.delta1010 { type hw card M1010 device 0 } # send to all outputs: pcm.multi { type plug ttable.0.0 1 ttable.0.1 1 ttable.0.2 1 ttable.0.3 1 ttable.0.4 1 ttable.0.5 1 ttable.0.6 1 ttable.0.7 1 ttable.0.8 1 ttable.0.9 1 slave.pcm delta1010 } pcm.mix { type plug ttable.0.10 1 # digital mix left ttable.1.11 1 # digital mix right slave.pcm delta1010 } Monitoring with mudita24, I see the individual levels well below +0 but the digital mixer showing OVER (well, peaked). 2 questions: 1) is this correct to sum the individual pcms (seems that's what it's doing) and 2) is that even correct? recording with arecord -c2 -r44100 -d10 -fS32_LE -V stereo never showed OVERs. Any insight? thanks David [1] http://alsa.opensrc.org/index.php/1712_.asoundrc
