### 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>[,mute=<gpio>[:0|1][,model=TAS57xx|TAS5713|AC101|I2S][,i2c=<addr>,sda=<gpio>,scl=gpio]
bck=<gpio>,ws=<gpio>,do=<gpio>[,mute=<gpio>[:0|1][,model=TAS57xx|TAS5713|AC101|I2S][,sda=<gpio>,scl=gpio[,i2c=<addr>]]
```
if "model" is not set or is not recognized, then default "I2S" is used. I2C parameters are optional an only needed if your dac requires and I2C control (See 'dac_controlset' below). Note that "i2c" parameters is decimal, hex notation is not allowed.
