NAME

       nasd.conf - Configuration file for NAS servers.

DESCRIPTION

       nasd.conf Is a file that can be used to configure the behaiviour of the
       NAS server, including what devices it will attempt to use, the  minimum
       &  maximum  frequencies  used,  if the device should be used in 8bit or
       16bit mode, what fragment size and number of fragments should  be  used
       (useful  for  tuning  the server’s latency) and if the server should be
       verbose when starting or output debugging information.  Not all options
       are  supported  for all servers, see the /etc/nas/nasd.conf.eg file for
       information on what options are supported for which servers.

THE CONFIG FILE SYNTAX

       There are up to three section in the config  file.  The  first  section
       deals  with global options, some of which just turn on verbose messages
       when parsing the config  file,  and  setting  debug  messages  on.  The
       remaining  two  sections will, if present, adjust various parameters of
       the input and output devices, for those server that undersand them.

       verbose Sets a flag telling the server to report what it’s trying to do
       with each setting in the config file.

       debug  <number>  Sets the debug flag, which will provide a trace of the
       server’s activities on  stderr.   Set  <num>  to  0  to  disable  debug
       messages, 99 for *alot* of debug messages.

       mixerinit  YES  |"NO" Set to "YES" to "NO".  Defines whether the server
       will init the mixer device on startup. (voxware)

       OutDevType EXT |"INT" For HPUX servers, define  to  "EXT"  to  use  the
       external  output  device (headphone/speakers) or "INT" for the internal
       output device (internal speaker).  Defaults to external.

       inputsection Marks the beginning of the  input  section,  which  allows
       various parameters of the input device to be set up.

       end Marks the end of the input section or output section.

       device  devname  Specifies  what  device  is used. An example is device
       "/dev/dsp".

       mixer mixername Specifies what mixer device  is  used.  An  example  is
       mixer "/dev/mixer".

       gain number Specifies the default volume (0-100). The default is 50.

       maxrate  number  the  maximum  number  of samples per second that we’ll
       drive the card at.

       minrate number the minimum number of samples per second that  the  card
       will be driven at.

       maxfrags  number  The  maximum number of of kernel buffers that will be
       used for the  device.   the  number  is  dynamically  adjusted  as  the
       sampling frequency varies.

       minfrags number The minimum number of kernel buffers that will be used.

       fragsize number The size of each buffer - note that the size must be  a
       power of 2.

       wordsize  number  The number of bits per sample. Allowable values are 8
       and 16.

       numchans number Used to decide if the card is run  in  stereo  or  mono
       mode. Allowable values are 1 or 2.

       forcerate  no  |"yes"  Forces  the output rate to the current rate. The
       default is "no".

       autoOpen no |"yes"  Whether  to  open  the  device  at  init  time  (if
       ReleaseDevice = no).  The default is "yes".

       readwrite  no |"yes" Whether or not to open the device read/write.  The
       default is "yes".  If set to "no", then for input devices,  the  device
       will be opened readonly, and for output devices, the the device will be
       opened writeonly.
