Ehm... guess what...
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 ;-)))
