Hello, My Raspberry pi is Model 3, and configure same as guideline below.

and I use speaker with 3.5mm audio jack (power adapter is USB).

and There is an issue I have:
After I used speaker, LED color were not change. and When I change the color of LED, Speaker said like "beep-beep".

So, I followed the guideline as below: 

#LED still shows the wrong color, rapidly flashes different colors, or flashes when audio is playing
$ sudo cp bootstrap/tjbot-blacklist-snd.conf /etc/modprobe.d/
$ sudo update-initramfs -u
$ sudo reboot

and also confirmed there is no snd module anymore.(using lsmod command).

But Now My raspberry pi could not recognize speaker.... How can I use LED and Speaker at the same time?

Thanks

Hi @GRuuuuu , are you able to try a USB audio adapter? E.g. something like this: https://www.adafruit.com/product/1475

We've never really found the built-in 3.5mm audio jack to be reliable with the LED. The workaround above has worked for us in the past, I'm struggling to figure out why it shouldn't work for you.
