No Hdmi Audio in Windows or Ubuntu.

  • I've tried windows 10 (1809) installed on the emmc, no audio output device is installed. In device manager no drivers for audio at all.

    In Ubuntu 18.10 cosmic installed on sd card aplay -l lists multiple outputs. Speaker-test produced no output. Powered with an xu4 5v4a plug into baby breakout board hdmi cable to samsung tv. Bluetooth audio works fine.

  • The only resolution I have found is lubantu 19.04 then it works from install.

  • Per a reddit post For windows you need to install Intel SST Audio Device (WDM) driver, which for whatever reason Windows cannot find and I cannot find a direct download link from Intel, but can be obtained through a driver manager software.

  • In Ubuntu 18.10, I forget exactly where, it may be Sound the output setting defaults to Analog. There is an option to change output to HDMI and all is well and sound blares. Sorry I forgot where the exact setting was.

    More of a nubie than a pro... supposedly the fix for HDMI audio for the version of Ubuntu on the emmc is here:
    In it, the author points to a config file at
    However, I have no idea how to run the config file and the screen prints he shows at is too blurry to see how its done.
    Can anyone tell me how to do the step to run the configuration file???

  • If you click on the images, then download them to your PC, you can view them in an image viewer. When you zoom in, the text is clear.

  • Log on Logan, his post is just alright.
    The best and confortable way to go is to install Lubuntu Disco 19.04 from the DLI system image. Then the sound cards work fluently and are easily switched back and forth. All applications that required sound are interfaced through the good embedded version of pulseaudio

  • 20.04 sound over HDMI works like a charm.
    I bet you can put 5V to the first pin as well, and have diminished volume audio over the audio pins.
