Liam,

I am wondering if OMAP4 has officially installed AIC31xx driver or not. If yes, where can I get it? See following ,

I have one aic31xx driver but it has problems to be second sound card if use sdp4430_snd_device = platform_device_alloc("soc-audio", -1); in sdp4430.c omap4_snd_device = platform_device_alloc("soc-audio", 1); in omap4_panda_aic31xx.c

or sdp4430_snd_device = platform_device_alloc("soc-audio", 0); in sdp4430.c omap4_snd_device = platform_device_alloc("soc-audio", 1); in omap4_panda_aic31xx.c

when mounting such as
