Valid commands are: .Bl -tag -width XgetXcodecidXnidX .It list For each child codec of the chosen .Xr hdaudio 4 device, display the nid, vendor, product, subsystem and device IDs. .It show Retrieve and display the current codec configuration in human-readable form. .It get Ar codecid Ar nid Retrieve and display the current codec configuration as a .Xr proplib 3 XML plist. .It set Ar codecid Ar nid Op Ar plist Detach the specified .Xr hdafg 4 codec and then re-attach with its widgets explicitly configured according to the specified plist. If no plist is given, the in-built widget parsing rules based on the High Definition Audio specification will be used. .It graph Ar codecid Ar nid Output a DOT file suitable processing by graphviz. The resulting image will graphically show the structure and interconnections of the widgets that form the chosen .Xr hdafg 4 codec. .El .Sh FILES .Bl -tag -width /dev/hdaudioX -compact .It Pa /dev/hdaudioX control devices .El .Sh SEE ALSO .Xr audio 4 , .Xr hdaudio 4 , .Pa pkgsrc/graphics/graphviz .Sh HISTORY The .Nm command first appeared in .Nx 5.1 . .Sh AUTHORS .Nm is based on two separate programs written by .An Jared McNeill Aq Mt jmcneill@NetBSD.org under contract by .Lk http://www.precedence.co.uk/ Precedence Technologies Ltd . Integration into one program and writing this manual page was done by .An Stephen Borrill Aq Mt sborrill@NetBSD.org . .Sh CAVEATS When a plist is loaded and the .Xr hdafg 4 codec reattaches, all mixer controls will be returned to their default values.
