No audio coming from the RPI audio connector

Open theshinyknight opened this issue 4 years ago • 3 comments

There is no audio output from the headphone connector on a raspberry pi 3. I see no settings available to change audio output, the only settings available are related to the SID chip. If you use a monitor that has no speaker basically you can't get audio out

Have you tried audio_out=analog ?

From README.md:

Q: Audio is not coming out of HDMI/Analog jack when I expect it to. Why?

A. Sometimes the code that auto detects whether audio should be piped through HDMI vs analog jack doesn't work. You can force audio to where you want it with a audio_out=hdmi or audio_out=analog parameter. The default is audio_out=auto. This ends up in cmdline.txt but you should set it in every machine config in machines.txt you want it to show up for.

Thanks; I must have missed that. I need to get the sd card out of the PI to modify those files; I have yet to find a way to switch to terminal and work in there (I filed an issue for that BTW).

That's because there's no terminal - or operating system, for that matter. That's what bare metal means. Yes, you have to remove the SD card (or USB flash drive) to make such changes.
