 ### DAC/I2S
 The NVS parameter "dac_config" set the gpio used for i2s communication with your DAC. You can define the defaults at compile time but nvs parameter takes precedence except for SqueezeAMP and A1S where these are forced at runtime. If your DAC also requires i2c, then you must go the re-compile route. Syntax is
 ```
-bck=<gpio>,ws=<gpio>,do=<gpio>
+bck=<gpio>,ws=<gpio>,do=<gpio>[,model=TAS57xx|TAS5713|AC101|I2S][,sda=<gpio>,scl=gpio]
 ```
+if "model" is not set or is not recognized, then default "I2S" is used. 
 ### SPDIF
 The NVS parameter "spdif_config" sets the i2s's gpio needed for SPDIF.
