I somehow missed that patchset or conversation; As an owner of an
X13s, which is sc8280xp, I can say, neither pre-dts patch, nor post,
seem to do much good.  When I attempt to do a voice chat in armcord,
the responses I get to how I sound when using the mic on the X13s
itself range from "You sound like hot trash" to "You sound like a
robot with hiccups".
