Hello, this is my first post. I got my first Pi to make a Minecraft Server, now I am trying to build a robot and automate Kombucha. What a rabbit hole!
I'm currently going through the book Learn Robotics with Raspberry Pi.
I am at the part where it is time to add sound to my robot. The sound will be
coming from a speaker connected to the raspberry pi 3.5mm jack. I am unable to get
sound on the raspberry.
As per the book I use the command:
sudo raspi-config
The book says to Force 3.5mm jack, but my option is different and can only chose "0 Headphones."
I just accept this and move on.
Book says to use command:
amixer set PCM 100%
This returns:
amixer: Unable to find simple control 'PCM',0
I know nothing, so I continue as the book says. Play the sound using command:
aplay horn.wav
A terrible rending and grinding comes out of the speaker. It does not stop until I kill the program.
I try the other sound:
aplay beep.wav
Which has the same result.
From my basic troubleshooting, I believe the Raspberry Pi is the problem. I have:
Confirmed Headphone Jack was the device (it was the only device).
Connected the speaker to something else, the speaker sound was fine.
Tested both sounds on a different device, sounds were fine.
Tested the HDMI. Changed device to HDMI (both devices were available now), restarted computer.
There was NO sound with HDMI.
Latest version of Raspberry PI OS.
I am learning my way through this. What other steps can I take to troubleshoot this issue?
