Subject: ALSA: usb-audio: Adjust Gamecom 780 volume level
From: Paul S McSpadden <[email protected]>
commit 542baf94ec3c5526955b4c9fd899c7f30fae4ebe upstream.
Original patch fixed the original problem, but the sound was far too low
for most users. This patch references a compare matrix to allow the
volume levels to act normally. I personally tested this patch myself,
and volume levels returned to normal. Please see this discussion for
more details: https://bugzilla.kernel.org/show_bug.cgi?id=65251
