Volume is very low, even when turning it to maximum. Everything worked fine under Ubuntu 14.04 that I was using before 15.04. I've reset the audio configuration with the command "rm -r ~/.config/pulse; pulseaudio -k" but it only fixes the issue temporarily. After each restart, the issue happens again and I have to execute the above command to get normal volume with headphones. Volume is normal with built-in speakers however.
