I don't have SPI or I2C to read/write my codec :-( I need to use read/write apis defined in <asm/intel_scu_ipc.h> int intel_scu_ipc_ioread8(u16 addr, u8 *data); int intel_scu_ipc_iowrite8(u16 addr, u8 data); and these can block a little while they get/set the data. But since that is not an issue, makes my life easy :-) Thanks ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
