My PiDog did have sound, but has now lost it. Steps I’ve taken to try and rectify are:
I have reinstalled the i2samp.sh multiple times and restarted the Pi. I have also run the sudo killall pulseaudio command, and then tried to run audio again, and it didn’t work.
I have also installed mplayer and tested with that, but still no sound. I’ve attached a screenshot of the attempt to run with mplayer:
I’ve done a physical inspection and there is no heatsink on my Pi that might be causing pressure on the speaker.
Can you please remove the robot hat and take a picture of the back side and confirm to us if the speaker is burned out yet.
Hello, pics attached. Many thanks
A replacement speaker will be sent to you, and a member of the after-sales team will contact you via your e-mail address later.
Tip: After replacing the speakers, please reinstall i2samp.sh and then go to run the sound example to see how it works.
Hi. I just bought PIDOG, the first installation was fine and the sound test was OK. After that, sound is not working anymore.
I tried to reexecute i2samp.sh several times, no sound.
I reinstalled all SD card from scratch, no sound.
I tried to play a wav file, no error but no sound.
please help!

I tried to force aplay to use pidog card:
aplay -D plughw:1,0 XXX.wav
but I got an error “Device or resource busy”
For info, I also noticed that, after reboot, the card number (aplay -l) of pidog audio card sometimes change from 1 to 2, and it is 1 again after executing i2samp.sh… but the error is always the same.
Can you remove the robot hat and take a picture of the back and verify that the speakers are not burned out.
