With device: AML-S905X-CC-V2 throught I2S port, I just connected a DFR0954 device with following scheme:
| Ref alias | Ref functions | DFR0954 |
|---|---|---|
| I2SOUT-CH01 | I2SOUT_CH01 | DIN |
| I2S-LR-CLK | I2S_LR_CLK_OUT | LRC |
| I2S-AM-CLK | I2S_AM_CLK | BCLK |
| GND | GND | GND |
| VDDIO_AO3.3V | 3.3V | VIN |
For enable DFR0954 device, inside my dts I added new node.

but when I launch: speaker-test -D hw:0,0 -c 2 -f 48000 -t wav the speaker connected to DFR0954 not produce any sound.
What am I doing wrong?
