Hi,
I am trying to use a HiFiBerry DAC as an output for my Raspberry Pi 5, which is running HassOS. I want to have my Rpi5 as an media player on Home/Music Assistant. However, the DAC does not appear as an available output device when I run ha hardware audio in the terminal. Can someone please help?
HAOS is not likely to have drivers for that. The OS will delete them if(when) you update it, and it is extremely unlikely to get it added to core.
You will need an add-on that someone has developed to make it work, or you need to install container HA and load the drivers in that base OS.
