22 | +## RPI I2S check |
|
23 | + |
|
24 | +Open the Raspberry Pi configuration tool: |
|
25 | + |
|
26 | + sudo raspi-config |
|
27 | + |
|
28 | +Navigate to Interfacing Options → I2S and enable it. |
|
29 | + |
|
30 | +Check if the module is loaded: |
|
31 | + |
|
32 | + lsmod | grep snd |
|
33 | + |
|
34 | +Look for snd_soc_bcm2835_i2s. |
|
35 | + |
|
36 | +Edit /boot/config.txt: |
|
37 | + |
|
38 | +Add the following lines to enable I2S and configure the DAC: |
|
39 | + |
|
40 | + dtparam=i2s=on |
|
41 | + dtoverlay=hifiberry-dac |
|
42 | + |

|
45 | + sudo reboot |
|
46 | + |
|
47 | +Verify Device Tree Overlay: |
|

|
49 | +After reboot, check for the overlay: |
|
50 | + |
|
51 | + dmesg | grep -i i2s |
