No, wait: I wrote some lines in asoundrc.txt: type meter # Meter PCM slave STR # Slave name (see pcm_slave) # or slave { # Slave definition or name pcm STR # Slave PCM name # or pcm { } # Slave PCM definition } [frequency INT] # Updates per second scopes { # Scopes ID STR # Scope name (see pcm_scope) # or ID { } # Scope definition (see pcm_scope) } # PCM scope type definition pcm_scope_type.NAME { [lib STR] # Library file (default libasound.so) [open STR] # Open function (default _snd_pcm_scope_NAME_open) } # PCM scope definition pcm_scope.NAME { type STR # Scope type ... } The rest is obvious, of course ;-)))
Well, you wrote that there is a sample implementation of this pcm_meter ,
but I can't find it (searched in alsa tools / utils , and searched with google with no good result)
Anyway, i'm going on trying to use it
Thanks
