NAME

       oss_sbpci - Creative Labs ES1371 audio driver.

DESCRIPTION

       Open Sound System driver for Creative Labs ES1371/ES1373/5880, Ectiva 1938 audio controllers.

       APCI97 device characteristics:

	      o  8/16 bit playback/record

	      o  mono/stereo playback/recording

	      o  8KHz to 48Khz sample rate

       APCI97 MIXER EXTENSIONS

       Dual  Dac  mode: This feature turns the APCI97 into two output devices with the output going to front and rear speakers independantly (how-
       ever volume control is global).

       Speaker Mode: This feature allows you to either have the audio coming out the front speakers or you  can  have  audio  duplicated  on  rear
       speakers. This mode is disabled when Dual Dac mode is enabled.

       SPDIF: This button enables or disables SPDIF output.

OPTIONS

       o  apci97_latency=<NNN>	Certain  models  of the ES1371 sound devices will sound distorted playing stereo audio and setting the PCI latency
	  fixes the problem

       o  apci_spdif=0|1 Certain models like the SB 4.1D/SB PCI128D have SPDIF output jacks and this setting enables the output device.

NAME

     snd_es137x -- Ensoniq AudioPCI ES137x bridge device driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device sound
	   device snd_es137x

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   snd_es137x_load="YES"

DESCRIPTION

     The snd_es137x bridge driver allows the generic audio driver sound(4) to attach to the Ensoniq 137x audio cards.

   Runtime Configuration
     The following sysctl(8) variables are available in addition to those available to all sound(4) devices:

	   hw.snd.pcm%d.latency_timer  Controls the PCI latency timer setting.	Increasing this value will solve most popping and crackling issues
				       (especially on VIA motherboards).

	   hw.snd.pcm%d.spdif_enabled  Enables S/PDIF output on the primary playback channel.  This sysctl(8) variable is available only if the
				       device is known to support S/PDIF output.

	   dev.pcm.%d.polling	       Experimental polling mode, where the driver operates by querying the device state on each tick using
				       callout(9).  Polling is disabled by default.  Do not enable it unless you are facing weird interrupt prob-
				       lems or if the device cannot generate interrupts at all.

HARDWARE

     The snd_es137x driver supports the following sound cards:

     o	 Creative CT5880-A
     o	 Creative CT5880-C
     o	 Creative CT5880-D
     o	 Creative CT5880-E
     o	 Creative SB AudioPCI CT4730
     o	 Ensoniq AudioPCI ES1370
     o	 Ensoniq AudioPCI ES1371-A
     o	 Ensoniq AudioPCI ES1371-B
     o	 Ensoniq AudioPCI ES1373-A
     o	 Ensoniq AudioPCI ES1373-B
     o	 Ensoniq AudioPCI ES1373-8
