Roger, OK, I just don't get it yet. This is from the Alsa page on the HDSP cards: ************* Since the Multiface only have 18 i/o channels, the channel mapping in the matrix mixer is different from the Digiface when operating at 48kHz or lower. [Ed. This is a routing table] input_source: 0-7 (analog), 16-23 (adat), 24-25 (spdif), 26-51 (playback) output_source: 0-7 (analog), 16-23 (adat) 24-25 (spdif), 26-27 (line out) ************* In your example above, is the use of 26 and 27 on the output part of the command telling the hardware to route whatever it is that you're mixing to the line out connectors on your box? Second, where do the inputs numbered 26-33 come from. I can't figure this part out. Are they outputs from the HDSP hardware mixer? Or do they mean from physical inputs? (somehow renumbered) This is the part I don't get right now. I presume that your use of 16384 is to reduce volume so that after summing 4 channels you do not create output clipping if all the inputs hit maximum volume at the same time? QUESTION - If you wanted to route input 0 directly to an output, could you use a command like: amixer cset numid=5 0,26,16384 amixer cset numid=5 1,27,16384 I think my HDSP 9652 will have different numbering since I have a different number of I/O's on the card, but I want to understand your example since it seems like a good one.
