HDAUDIOCTL(8)               System Manager's Manual              HDAUDIOCTL(8)

NAME
     hdaudioctl - program to manipulate hdaudio(4) devices

SYNOPSIS
     hdaudioctl [-f device] command [arguments]

DESCRIPTION
     The hdaudioctl command can be used to inspect and reconfigure High
     Definition Audio devices and their child codecs.

     The mandatory command argument specifies the action to take.  Valid
     commands are:

     list               For each child codec of the chosen hdaudio(4) device,
                        display the nid, vendor, product, subsystem and device
                        IDs.

     show codecid nid   Retrieve and display the current codec configuration
                        in human-readable form.

     get codecid nid    Retrieve and display the current codec configuration
                        as a proplib(3) XML plist.

     set codecid nid [plist]
                        Detach the specified 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.

     graph codecid 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 hdafg(4) codec.

AUTHORS
     hdaudioctl is based on two separate programs written by Jared McNeill
     <jmcneill@NetBSD.org> under contract by Precedence Technologies Ltd:
     http://www.precedence.co.uk/. Integration into one program and writing
     this manual page was done by
     Stephen Borrill <sborrill@NetBSD.org>.

CAVEATS
     When a plist is loaded and the hdafg(4) codec reattaches, all mixer
     controls will be returned to their default values.
