No sound coming out of speakers, and I don't know why? :(

Pisound
1

Hi there, I had my PiSound for quite a while and I never had been able to get any sound off from the device. Ever. Even as simple as video or audio file played can’t produce any sound. I don’t what I should be looking for exactly and I wanted to reach out for help. I’m pretty familiar with Raspberry pi’s but this particular Hat is pretty new to me, so I am quite the noob in regards to the pisound.

But any questions or help would be very well appreciated, and I’d love to start using this device to work on some projects I have in mind.

I have used the following commands (plus the dmesg.log at the bottom):

patch@patchbox:~ $ amidi -1

dmesg.log (45.3 KB)

I’m not sure exactly what I should be looking for or why it’s been acting this way, but I know this is issue that needs fix.

Hi, I don’t see any issues in your command outputs or dmesg log. What are you testing the output with? Could you try hooking up some plain headphones? Make sure to turn the Volume potentiometer up.
