If anyone has any objections, please let me know. ------------------ From: Paul S McSpadden 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.
