Check technical details and commands against the product version and manufacturer documentation before use.<br /> <br /> == Summary ==<br /> The Audio Driver HAT is an audio module for the Sunrise X3 PI. It uses the ES7210 four-channel codec and the ES8156 stereo decoder, is controlled via I2C, and transfers audio over I2S. The board includes a 3.5 mm headphone jack and four corner-mounted MEMS microphones for stereo recording.<br /> <br /> == Related products at JW Tech ==<br /> * [https://shop.jw-tech.eu/p/WSAL23898 WSAL23898 – Audio Driver Board for RDK X3 Development Board, Supports Audio Playback And Recording, Stereo Encoding / Decoding, Onboard Headphone Jack And 4-Ch Microphones]<br /> <br /> == Technical overview ==<br /> * Supply voltage: 3.3 V<br /> * Control interface: I2C; audio interface: I2S<br /> * ADC SNR: 102 dB; DAC SNR: 110 dB<br /> * V2 version compatible with RDK X3 V1.2/V2.1, RDK X3 MD, and RDK X5<br /> * Configuration via `sudo srpi-config` under Interface Options -&amp;gt; I5 Audio<br /> * Driver configuration removal through the same path by selecting UNSET<br /> * Recording with tinycap (e.g., 4 channels, 16-bit, 48 kHz)<br /> * Playback only supports 2-channel audio via tinyplay; direct playback of 4-channel recordings is not supported<br /> * For S100: DIP switches must be set correctly (40PIN left, PCM right), otherwise recording/playback will not work<br /> * S100 drivers are loaded dynamically as kernel objects<br /> <br /> &#039;&#039;&#039;Commands and examples – verify before use:&#039;&#039;&#039; <br /> &lt;syntaxhighlight lang=&quot;text&quot;&gt;<br /> sudo srpi-config<br /> sudo tinycap ./4chn_test.wav -D 0 -d 0 -c 4 -b 16 -r 48000 -p 512 -n 4 -t 5<br /> sudo tinycap ./2chn_test.wav -D 0 -d 0 -c 2 -b 16 -r 48000 -p 512 -n 4 -t 5<br /> sudo tinyplay ./2chn_test.wav -D 0 -d 1<br /> sudo i2cdetect -r -y 0<br /> sudo modprobe es7210<br /> sudo modprobe es8156<br /> sudo modprobe hobot-i2s-dma<br /> sudo modprobe hobot-cpudai<br /> sudo modprobe hobot-snd-7210 snd_card=5<br /> ls /dev/snd<br /> arecord -Dhw:0,0 -c 2 -r 16000 -f S16_LE -t wav -d 5 test.wav<br /> aplay -Dhw:0,1 test.wav<br /> sudo modprobe hobot_cpudai_super<br /> sudo modprobe snd-soc-es8156<br /> sudo modprobe snd-soc-es7210<br /> sudo modprobe hobot_snd_s100_ac_fdx_host<br /> cat /proc/asound/cards<br /> ls -l /dev/snd<br /> sudo rmmod es8156<br /> &lt;/syntaxhighlight&gt;<br /> <br /> == Notes and version constraints ==<br /> * Compatibility with specific RDK revisions should be verified before purchase or installation<br /> * For older V1 versions, multiple drivers must be loaded manually; if loading fails, check device nodes under /dev/snd<br /> * Correct DIP switch positioning on the S100 is critical; incorrect settings prevent normal recording and playback<br /> * The smart voice environment requires TogetherROS; errors or warnings during startup may appear and should be ignored<br /> * Direct playback of 4-channel recordings is explicitly not supported<br /> * Version-specific steps (such as miniboot updates on newer systems) may require manual confirmation by a technician<br /> <br /> == Source and revision record ==<br /> * [https://www.waveshare.com/wiki/Audio_Driver_HAT Audio Driver HAT - Waveshare Wiki]<br /> * Source revision: 110806<br /> * Captured: 2026-09-04T03:34:05+00:00<br /> * SHA-256: &lt;code&gt;391e724dd5ef3aa2807b9530205d98138dd77abf6bca60cee2449eba2e80ec4f&lt;/code&gt;</div>
