DAC2 HD No sound

Hello,

I wrote a fresh HifiBerry OS on a Sandisk Ultra 32GB (the goldish color) card, setup network and enabled connection via ssh. aplay -l seems to recognize my DAC2 HD sound card, but no sound even with the check-system.dac utility. What am I doing wrong?

Looks fine. What do you do to play music?

btomi9 March 21, 2024 07:55

At first I tried to run check-system.dac but also some local music from hifiberry.local web interface. There is no error message, but there is absolutely no sound.

I have a hint though. I lost somewhere my original RPi 5V wallplug PSU and now I try to use a 65W really heavy powerbank with a thick type C cable. Not sure however if it gives real 5V, but RPi boots and works fine. Might this be the problem?

HiFiBerry team March 21, 2024 07:56

No, if the Pi boots, that's just fine.

The check-system.dac is an old script. I wasn't aware that this still exists, but it's pretty useless.

Try

play -n synth sine 1000

btomi9 March 21, 2024 10:54

This is the output, but still no sound. Double checked the cable and the amp/speakers, they are working with my windows PC.

# play -n synth sine 1000

btomi9 March 22, 2024 11:22

Is there some other way that I can test the device and make sure it is not a hardware failure? I bought it last summer, shall I return it for warranty replacement?

HiFiBerry team March 22, 2024 11:24

Not really. If you bought it directly fro us, contact us at support@hifiberry.com. We can check the board in our lab.

btomi9 March 25, 2024 17:38

I checked the DAC board with my other RPi 4, even tried it with the original RPi power supply, and also tried to make a .asoundrc file under root's home dir with

# cat .asoundrc
pcm.!default {
        type hw
        card 0
}

ctl.!default {
        type hw
        card 0
}

So I think there is nothing more to try :(
