[alsa-devel] tlv320aic3104

Beginner query. I'm modifying the codec driver for tlv320aic3104 and wanted to control inputs to a mixer.One of them being page 0/register 17. It basically has input level control(0-0x8) and then 0xf(which is off) and the values in-between 0x8-0xf as invalid. How to give the input to mixer?As a switch or volume/bias control and what is the most likely macro to be used. DAPM_SINGLE?
