NAME

       snd_ac97_tune_hardware - tune up the hardware

SYNOPSIS

       int snd_ac97_tune_hardware(struct snd_ac97 * ac97, struct ac97_quirk * quirk, const char * override);

ARGUMENTS

       ac97
	   the ac97 instance

       quirk
	   quirk list

       override
	   explicit quirk value (overrides the list if non-NULL)

DESCRIPTION

       Do some workaround for each pci device, such as renaming of the headphone (true line-out) control as "Master". The quirk-list must be
       terminated with a zero-filled entry.

RETURN

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

NAME

     ac97 -- generic AC97 codec driver

DESCRIPTION

     AC97 codecs contain the analog-to-digital (A/D), digital-to-analog (D/A), and mixing circuitry of many modern sound cards.  AC97 codecs, for
     the most part, do not talk to host busses like the PCI bus directly.  Instead, they communicate through an interface chip, called the host
     controller.  The Ensoniq AudioPCI 97 (see eap(4)) is an example of such a host controller.

     Unlike many drivers, the ac97 driver does not appear in the configuration file.  Instead, the driver is automatically attached by the drivers
     that require it.

BUGS

     The ac97 driver does not keep track of the current user settings and instead relies on the hardware to do this.

     The ac97 driver could do more to detect mixer channels that don't work and cull them from the list.
