This is interesting, I have an a5 and the default value of FSO M4.1a:
control.4 {
comment.access 'read write'
comment.type INTEGER
comment.count 2
comment.range '0 - 127'
iface MIXER
name 'Speaker Playback Volume'
value.0 116
value.1 116
}
Sometimes I ask people on the other side: do you hear echo? The answer
has been no.
