No sound with Pirate Audio line out

Support
1

Hi

I’ve got a problem setting up my Pirate Audio line out hat.
Display is up and running, but I get no sound.
Other posts have succeeded by commenting out #dtparam=audio=on from /boot/config.txt.
This hasn’t worked for me.
Testing with “speaker-test”, or omxplayer with a suitable .mp3 player doesn’t work.

Any ideas?
Steve

Same problem for me.

As far as i can tell everything it working fine on the software side but no sound.

Have tried two sets of speakers and mulitple other sources so it is definitely not the speakers or cables etc.

Anybody else have any success if the /boot/config.txt edit doesnt work?

Hi
The issue for me was that it was a faulty board, which the folks here replaced.
Replacement board worked first time, as have other boards I have ordered since.

It is the Line-out version that you have? That can drive low impedance headphones quite well (which means you can test with a cheap set of supermarket headphones) but won’t drive speakers unless you put an amplifier inbetween…

Hey sdhip

Thanks for the response and to the Pimoroni guys and gals who offered to send a replacement board. It turns out in my case that the board wasnt faulty after all. Currently working fine after doing a fresh install on a reformatted SD card.

All i can say is if you have any problems and havent followed the recommendation for a fresh install then give it another go after a fresh install on a re-formatted SD card. In my case I suspect a problem with GPIO pins related to a previous use of the Raspberry Pi.
