Bug Description
Hi,
I have a O2+ODAC USB DAC unit.
14.04/15.10 output volume level is identical to Windows; in my case this means that low gain and volume knob @ 12:00 is as loud as my ears can handle.
Installed 16.04 today, volume level is considerably lower vs Windows now. I can now play at high gain and max volume and volume level is just bearable. I would run into limits of my headphones or hit the pain threshold if I tried this in Windows.
I've tried adjusting the volume levels in the volume control for both the app and the system level, both are at 99% and volume level is low. Allowing above 100% results in destortion but not reaching previously attainable volume levels.
Im a techy user and capable of advanced troubleshooting if required.
Alan

I checked in Alsamixer / pressed f6 / selected my sound card and found the volume to be set at a reduced level. I increased the volume and noted that original performance was restored.
This isnt exposed in the graphical volume controls for some reason...
