3.5mm audio output volume

Wed Aug 31, 2016 1:49 am

I have a Python 3 app that plays audio using pygame. The audio output using headphones is okay, but if I plug the audio into my car's AUX input, the volume is very low. I have to turn the car's volume WAY up and the sound is still low. Running a Pi 2 under Jessie.

Suggestions?

Should have noted that pygame volume is set to the maximum. I've also tried a few scripts that adjust volume with no luck.

Xwindows volume control determines the whole system sound level. You may set the volume to maximum on the GUI and logout from Xwindows. The volume will stay the given value.

Try also checking if there are extra audio controls from alsamixer.

Check the Ultra 2 sound card - use our shop instead of Amazon Europe (Amazon USA is live).
