No audio from headphone jack (Pi4) - batman75 - 04-30-2024
Hello
Sorry, I have tried searching for this problem but couldn't find anything specifically relating to this.
I've just tried connecting my Pi4 to my amp using a standard 3.5mm-2 phono cable, but I'm getting no sound out of the amp. I've tried a couple of RCA inputs on the amp, and then retested on a second amp, both of which are happily playing sound from my turntable. I'm not sure if there are specific moode settings I need to configure, but I'm hoping I can use this setup rather than buying a separate audio hat for the pi.
I've tried all volume options on the Audio menu, and kept both Named I2S device and DT overlay set to None. Is there anything else I should be doing?
Any advice will be greatly appreciated. Many thanks.

Reboot and then post the contents of the startup log.
The log can be viewed via the SSH command moodeutl -l or downloaded via the Logs section in System Config, or via Menu, System info from the any of the Config screens. The startup log will be at the end of System info output.

RE: No audio from headphone jack (Pi4) - Tim Curtis - 04-30-2024
I don't see anything suspicious in the log.The audio device and volume configuration looks fine.
When something is playing the "Audio info" screen will show the PCM stream attributes in the "Output format" line. If this is happening in your case then its a mystery to me why there is no volume output.
RE: No audio from headphone jack (Pi4) - TheOldPresbyope - 05-02-2024
@batman75
So you said "I've just tried connecting my Pi4 to my amp using a standard 3.5mm-2 phono cable, but I'm getting no sound out of the amp."
That 3.5mm jack on the Pi looks like an ordinary headphone jack but it's actually a 4-pole audio and video jack. Not all 3.5mm-to-RCA patch cords are wired the same (the wonderful thing about standards is there's so many of them).
It's likely your patch cable is correct but an easy way to check is to plug in headphones directly instead (for test purposes, I use the wired earbuds that came with some phone or another in the past).
If you hear audio through the headphones and you can control the volume from the moOde WebUI then moOde is configured correctly. Your problem is either in the patch cable or in a mismatch between the output level of the Pi and the input sensitivity of your amp.

Kent
RE: No audio from headphone jack (Pi4) - Phil323UK - 05-03-2024
Just to add to Kent's reply.
Raspberry Pi's 1-4 have a 3.5mm TRRS (tip, ring, ring, spacer) socket.
So you will need a cable with a 3.5mm TRRS jack to connect to your amp.
So headphones with an inline microphone should work with no problem.
