Bug Description
When I use the multimedia keys and let pulseaudio set the volume, the sound is already distorted halfway. 100% Master volume means 0dB, but 100% PCM volume means +35dB, which produced distorted output.

Please reassign this bug to the linux package. It's really a hardware issue default. pa (or default. pa).
that we can attempt to work around in the sound driver. In the meantime, try
passing ignore_dB=1 to module-udev-detect in /etc/pulse/
~/.pulse/
