Microphone volume low on linux driver

[Eric Curtin <ericcurtin17@xxxxxxxxx>]

Hi Guys,

I have a headset, Linux recognizes it as "HyperX Virtual Surround Sound
Digital Stereo", I have it set to 150% recording volume. It's a "HyperX
Cloud II" headset, the Windows seems to work fine. I also tried
"Digital Stereo (IEC958) Input" mode.

Is there a quirk or similar in the kernel I can set in order to
increase the recording volume of this device specifically?

Some details about my system (it's xubuntu):
