ac97_patch.c provides two helper functions that wrap the channel_mode variable, but they only take you out to 5.1 Audio:
static inline int is_surround_on(struct snd_ac97 *ac97) { return ac97->channel_mode >= 1; }
static inline int is_clfe_on(struct snd_ac97 *ac97) { return ac97->channel_mode >= 2; }
For 7.1 Audio, i think there needs to be a test for 'Surround Back' or 'Back Surround'
static inline int is_surback_on(struct snd_ac97 *ac97) { return ac97->channel_mode >= 4; }
Am i correct? or am i mistaken? agreement or corrections appreciated!
It's correct. The code for 7.1-audio capability was added recently.
Good. I'm not crazy then. Ok, maybe i am, but not about this. :-)
I'll submit this in follow on work to support creating an improved via8237.conf
tnx!
