## Cloning
```sh
git clone [https://github.com/denisgav/rpi_usb_sound_card.git](https://github.com/denisgav/stm32f401ccu6_uac2_headset.git)
```
## Default Pinout
### PCM5102a DAC
* PCM5102A configuration inputs:
* FLT - Filter select : Normal latency (Low) / Low latency (High)
* DEMP - De-emphasis control for 44.1kHz sampling rate: Off (Low) / On (High)
* XSMT - Soft mute control(1): Soft mute (Low) / soft un-mute (High)
* FMT - Audio format selection : I2S (Low) / Left justified (High)
* PCM5102A I2S interface:
* SCK - System clock input
* BCK - Audio data bit clock input
* DIN - Audio data input
* LRCK - Audio data word clock input
