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
