Hi, it is possible to control the hdsp mixer via amixer. Here is what I use to route software out 1+2 to ADAT1 1+2 and SPDIF (on an HDSP 9652), it is part of /etc/rc.local: /usr/bin/amixer -q -D hw:DSP cset numid=5 26,24,32768 /usr/bin/amixer -q -D hw:DSP cset numid=5 27,25,32768 /usr/bin/amixer -q -D hw:DSP cset numid=5 26,0,32768 /usr/bin/amixer -q -D hw:DSP cset numid=5 27,1,32768 The syntax is "source channel,target channel,gain", where source channel is 0-25 = hardware in, 26-51 = software-out, and hardware channel 0-25 is hardware out (all on hdsp9652, but it is nearly the same on hdsp9632 and multiface). The gain is 32768 for maximum. I forgot, but sometimes this means 0 dB and sometimes it means +6 dB. Once I was thinking of implementing a command line application of hdspmixer with OSC interface, however I gave up because I don't need it any more (and most of it is supported by amixer). And if I remember well Florian Faber mentioned that he was implementing something similar. -- Giso Klaus Schulz wrote: > Hello all. > > I am new to the list.
