Information about mixer routes
typedef struct snd_mixer_routes_s { snd_mixer_eid_t eid; int32_t routes, routes_size, routes_over; uint8_t zero[4]; /* alignment -- zero fill */ snd_mixer_eid_t *proutes; void *pzero; /* align pointers on 64-bits; point to NULL */ uint8_t reserved[128]; /* must be filled with zeroes */ } snd_mixer_routes_t;
The snd_mixer_routes_t structure describes all of the routes in a mixer. You can fill this structure by calling snd_mixer_routes().
The members of the snd_mixer_routes_t structure include:
If proutes isn't NULL, snd_mixer_routes() stores the route IDs in the array.
