unclear example how to use remap plugin
by GitHub issues - opened 01 Mar '25

01 Mar '25

alsa-project/alsa-lib issue #441 was opened from dibalavs: Hello. I combiled 3 sound cards into one vrurtual 5.1 card for PCM, and now trying to make volume control also to use single virtual device, to set up volume for all chanel of virtual 5.1 card. I am trying to use remap control plugin mentioned at [source](https://github.com/alsa-project/alsa-lib/blob/master/src/control/co… But I unable to understand what does it mean: ``` ctl.name { type remap # Remap controls child STR # Child name # or child { # Child definition type STR ... } remap { # the ID strings are parsed in the amixer style like 'name="Headphone Playback Switch",index=2' SRC_ID1_STR DST_ID1_STR SRC_ID2_STR DST_ID2_STR ... } map { # join two stereo controls to one CREATE_ID1_STR { SRC_ID1_STR { vindex.0 0 # source channel 0 to merged channel 0 vindex.1 1 } SRC_ID2_STR { vindex.2 0 vindex.3 1 # source channel 1 to merged channel 3 } } # split stereo to mono CREATE_ID2_STR { SRC_ID3_STR { vindex.0 0 # stereo to mono (first channel) } } CREATE_ID3_STR { SRC_ID4_STR { vindex.0 1 # stereo to mono (second channel) } } } } ``` I do not understand what should I write as SRC and DST?: ``` # the ID strings are parsed in the amixer style like 'name="Headphone Playback Switch",index=2' SRC_ID1_STR DST_ID1_STR SRC_ID2_STR DST_ID2_STR ``` Can you give real example without placeholders like: "name", "SRC", "DST", "STR" ?
