YAML example Placeholder
I2C
The I2C device id depends on the ADDR0 and ADDR1 pin settings and needs to be set according to your board setup.
| ADDR1 | ADDR0 | I2C device id |
|---|---|---|
| 0 | 0 | 0x64 |
| 0 | 1 | 0x65 |
| 1 | 0 | 0x66 |
| 1 | 1 | 0x67 |
In this example we assume ADDR0=0 and ADDR1=0.

ALSA controls can be modified easily using alsa-tools utilities. For example to read the current state of DMIC0 Capture Volume control one can use:
amixer -c ADAU1860 cget name='DMIC0 Capture Volume'
To set one control value the following command can be executed:
amixer -c ADAU1860 cset name='DMIC0 Capture Volume' 191
