When using earbuds in the 3.5mm jack, my phone plays music (e.g. with Google Play Music, Pandora, etc.) through the earbuds as expected. But, if I use the Settings -> Sound screens to modify ringtones or notification sounds, the audio plays through the phone speaker rather than through the earbuds. I've tried resetting the phone and I've tried multiple sets of earbuds which work fine on other devices.
