Headphone jack is kinda quite

#1

Hello sorry if there is a existing thread I could have asked this in. When I use my over ear headphones with the pi sound I have to turn the volume all the way up. Even then it’s just a shade quite for me. I don’t have this issue with any other device I listen to music on. Is it possible I’m under powering the board?

Hey, it depends on the kind of headphones you use, especially their impedance parameter, the lower it is, the less amplification is required for them to sound loud. Pisound’s output is at line level which allows it to be connected to a wide range of other devices, but an amplifier may be necessary to use Pisound with high impedance headphones or speakers.

Underpowering Pisound is possible, but in that case, either audio wouldn’t work at all, or you would hear some noise where there shouldn’t be any. Just in case, you can check the output of dmesg and see if there’s any ‘undervoltage’ warnings printed. Some may appear at the time the Raspberry Pi was just powered on, but you shouldn’t see any after the system has fully booted.

And just in case, double check the volume output level of the software you are using, if it’s at 100%. :slight_smile:
