You can't make ALSA work just by turning on a couple of drivers in menuconfig. You have to provide a machine driver that tells ALSA how to connect the generic codec driver to the processor's I2S unit. The machine driver is specific to the piece of hardware you are designing. > > ./atmel/atmel_wm8904.c > ./atmel/sam9g20_wm8731.c > ./atmel/sam9x5_wm8731.c > ./tegra/tegra_wm8753.c > ./tegra/tegra_wm9712.c > ./tegra/tegra_wm8903.c > ./samsung/neo1973_wm8753.c > ./samsung/smdk_wm9713.c > ./samsung/smdk_wm8580pcm.c > ./samsung/goni_wm8994.c > ./samsung/smdk_wm8994pcm.c > ./samsung/jive_wm8750.c > ./samsung/smdk2443_wm9710.c > ./samsung/smartq_wm8987.c > ./samsung/smdk_wm8994.c > ./samsung/smdk_wm8580.c > ./pxa/e740_wm9705.c > ./pxa/e750_wm9705.c > ./pxa/e800_wm9712.c > ./pxa/mioa701_wm9713.c > > >> >> Regards >> Punith >> >> -- >> You received this message because you are subscribed to the Google Groups >> "linux-sunxi" group. >> To unsubscribe from this group and stop receiving emails from it, send an >> email to linux-sunxi+unsubscr...@googlegroups.com. >> For more options, visit https://groups.google.com/groups/opt_out. > > > > -- > Jon Smirl > jonsm...@gmail.com -- Jon Smirl jonsm...@gmail.com -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
