Hi. I am building a HA HighQuality sound sytem.
As output i use a FosiAdio UsbDac and a SoundBlaster Audigy.
Quality is great.
But i also have a Usb DAB+ receiver that goes to the line input off the Sb Audigy.
In the linux command line , with alsamixer , this works fine.
But how to control , at least the line in volume , in HOMEASSISTANT?
