p The .Fl n flag suppresses printing of the variable name. .Sh EXAMPLES To set the playing sampling rate to 11025 you can enter .Dl audioctl -w play.sample_rate=11025 Note that many of the variables that can be inspected and changed with .Nm audioctl are reset when the device is opened. This can be circumvented like this .Dl (cat file.au; audioctl -f /dev/stdout -a) > /dev/audio or .Dl (audioctl -f /dev/stdout -w blocksize=1024; cat file.au) > /dev/audio .Sh FILES l -tag -width /dev/sound t Pa /dev/sound audio device .El .Sh SEE ALSO .Xr mixerctl 1 , .Xr audio 4 , .Xr sysctl 8 .Sh HISTORY The .Nm audioctl command first appeared in .Nx 1.3 .
