No Hdmi Audio in Windows or Ubuntu.

Jun 1, 2019 - 11:02 AM

  • 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.

  • 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.

  • HELP NEEDED!
    More of a nubie than a pro... supposedly the fix for HDMI audio for the version of Ubuntu on the emmc is here: https://www.reddit.com/r/Atomic_Pi/wiki/index#wiki_fix_for_hdmi_audio
    In it, the author points to a config file at https://pastebin.com/raw/ztaEfCj0
    However, I have no idea how to run the config file and the screen prints he shows at
    http://linuxiumcomau.blogspot.com/2017/10/fixing-broken-hdmi-audio.html is too blurry to see how its done.
    Can anyone tell me how to do the step to run the configuration file???
    Thanks

  • 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.
