Hi all,
I'm struggling with getting the correct names for controls, so that they show up correctly in the Playback or Capture modes of alsamixer
E.g. "PCM 3 Capture Meter" appears in the playback controls?
How is capture vs playback display determined? or to put it another way: What are the rules for creating control names.
Here is a reduced schematic of one of our cards (in reality more channels e.g. 4 physical stereo ins and outs, 12 players, 8 recorders) All players and inputs are mixed to outputs. All inputs and players multiplexed to each capture.
How should all these controls be named?
(1)-[vol]--+ (2)-[vol]--+ [play0]--[vol]--[meter]--[mode]--,-[vol]--+----[vol]-[meter]--[level]--[lineout0] `-[vol]--|-. | | .-[vol]--' | [play1]--[vol]--[meter]--[mode]--'-[vol]----+--[vol]-[meter]--[level]--[lineout1] (1)-[vol]----+ (2)-[vol]----+
[linein0]-[level]-\ \ mux>-[meter]-(1)-,-------|\ [digitalin0]------/ | mux >--[mode]--[meter]--[cap0] | ,../ | | `--|--\ [linein1]-[level]-\ | >--[mode]--[meter]--[cap1] mux>-[meter]-(2)-----'--/ [digitalin1]------/
notes [level] means calibrated reference level setting in dBu [mode] stereo channel modifier + summing junction --|-- wires cross, no join (1) connect from input to matrix mix output
thanks and regards
