Hi Mark,

You need to create the control device, then open that using virtual_oss_ctl
(QT5 GUI) from ports.

virtual_oss_ctl  -h
usage: virtual_oss_ctl -f /dev/vdsp.ctl

Then you can change the volume and do some other stuff as needed.

Virtual OSS also supports the volume IOCTLs on the dsp devices, but these must
be invoked from the application itself.
