for each additional client expected
(115 if 2 clients are expected, 103 for 3 clients, and so on).
.It Fl w Ar flag
Control whether the master volume resulting of all playback
streams of the device is automatically adjusted.
Control

behaviour when the maximum volume of the hardware is reached
and a new stream is connected.
This happens only when stream volumes
are not properly set using the
.Fl v
option.
If the flag is
.Va on ,
then the master volume is lowered when necessary to ensure
clipping never occurs.
It should be set to
.Va off
to avoid lowering the volume twice if streams are already pre-scaled.
Note that stream volumes can be manually set
.Pq Fl v
and if they are set correctly, the master volume doesn't need
to be adjusted to avoid clipping.
then the master volume (corresponding to the mix of all playback streams)
is automatically adjusted to avoid clipping.
Using
.Fl w Va off
makes sense when all streams are recorded or produced with properly lowered
volumes.
The default is
.Va on .
