Available options are:
.RSs
.IPs device=<value>
Radio device to use (default: /dev/radio0).
Radio device to use (default: /dev/radio0 for Linux and /dev/tuner0 for *BSD).
.IPs driver=<value>
Radio driver to use (default: v4l2 if available, otherwise v4l).
Currently, v4l and v4l2 drivers are supported.
.IPs volume=<0..100>
sound volume for radio device (default 100)
.IPs freq_min=<value> (*BSD BT848 only)
minimum allowed frequency (default: 87.50)
.IPs freq_max=<value> (*BSD BT848 only)
maximum allowed frequency (default: 108.00)
.IPs channels=<frequency>\-<name>,<frequency>\-<name>,...
Set channel list.
Use _ for spaces in names (or play with quoting ;-).
