I am very new to Elk Audio OS, and have been trying to solve this myself for the past couple days, but I can’t get my HifiBerry DAC+ ADC Pro to initialize. The lights do not turn on when I’m using Elk Audio OS. They do on other OS’s when I’m using the board.
I tried running sudo elk_system_utils --set-audio-hat hifiberry-dac-plus-adc-pro but get the response The audio HAT is autodetected by load-drivers script.
My /tmp/audio_hat value is hifi-berry-pro. But when I run the test sushi -r --multicore-processing=2 -c ~/config_files/play_vst3.json & nothing happens.
Here’s the output from my sushi log after running the stated command:

Hi matdave and welcome to the forums. From the sushi logs you’ve posted, it looks like everything has been set up as it is supposed to be and the audio driver is working. Sushi should have quit with an error message if it wasn’t able to connect to the driver.
This is honestly the first time I’ve heard about an led on the hifiberry, so I would guess (though I didn’t write the driver) that the led was added in another revision and we never implemented support for it.
The play_vst3.json config file that’ve you used loads a vst synth on a track, but in order to play it you need to connect a midi keyboard and connect that to sushi using aconnect . Se here for a more detailed description Running Elk on your computer — Elk DevKit documentation
Gustav,
Interesting, on other OS’s the Input and Output light up when they are in use. Maybe it’s a new thing. In any case, what would be a way to just test that it is working? I can’t get it to output anything so far.

You could try the play_arp_mda_link.json config file. It contains an arpeggiator and a synth so it should output something. Another option is to use the empty.json config file and send audio from input to output. It should pass through unchanged. If not let us know.
If you run with an & at the end of the comandline, to give control back to the terminal, remember to kill the first instance of sushi before launching a new one
As for the LED, maybe @Nitin can give some information if we support that or not.
Awesome, it does work. I just had my wires crossed going in. Had a mono->stereo plug in and a stereo>mono plug coming out but for some reason the left was taking priority on the in and right was taking priority on the out. It was working just not showing LEDs which threw me off.

Happens to the best of us :). Great that you got it working and good luck with your project!
