It seems to me that this is something that one might want to fill out on a per card/motherboar basis, because it appears that there functions that try to make decisions based on it's status:
/* system has shared jacks with surround out enabled */
static inline int is_shared_surrout(struct snd_ac97 *ac97)
{
return !ac97->indep_surround && is_surround_on(ac97);
}
/* system has shared jacks with center/lfe out enabled */
static inline int is_shared_clfeout(struct snd_ac97 *ac97)
{
return !ac97->indep_surround && is_clfe_on(ac97);
}
/* system has shared jacks with line in enabled */
static inline int is_shared_linein(struct snd_ac97 *ac97)
{
return !ac97->indep_surround && !is_surround_on(ac97);
}
/* system has shared jacks with mic in enabled */
static inline int is_shared_micin(struct snd_ac97 *ac97)
{
return !ac97->indep_surround && !is_clfe_on(ac97);
}
so, where do i set this thing? how do i distinguish between a chip installed on a board/card with 3 bidirection plugs vs a board with several dedicated ins and outs?
or, is this whole thing an idea that is in the code but not actively utilized?
tnx!
