SND_AC97_PCM_OPEN(9)						 Control/Mixer API					      SND_AC97_PCM_OPEN(9)

NAME

       snd_ac97_pcm_open - opens the given AC97 pcm

SYNOPSIS

       int snd_ac97_pcm_open(struct ac97_pcm * pcm, unsigned int rate, enum ac97_pcm_cfg cfg, unsigned short slots);

ARGUMENTS

       pcm
	   the ac97 pcm instance

       rate
	   rate in Hz, if codec does not support VRA, this value must be 48000Hz

       cfg
	   output stream characteristics

       slots
	   a subset of allocated slots (snd_ac97_pcm_assign) for this pcm

DESCRIPTION

       It locks the specified slots and sets the given rate to AC97 registers.

RETURN

       Zero if successful, or a negative error code on failure.

NAME

     snd_mss -- Microsoft Sound System ISA PnP/non-PnP bridge device driver

SYNOPSIS

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

	   device sound
	   device snd_mss

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

	   snd_mss_load="YES"

     Non-PnP cards require the following lines in device.hints(5):

	   hint.pcm.0.at="isa"
	   hint.pcm.0.irq="10"
	   hint.pcm.0.drq="1"
	   hint.pcm.0.flags="0x0"

DESCRIPTION

     The snd_mss bridge driver allows the generic audio driver, sound(4), to attach to the supported audio devices.

HARDWARE

     The snd_mss driver supports the following audio devices:

     o	 AD1845
