>Description:
It is already known that some machines that uses ich(4) sound driver must turn on inverted external amplifier sense flag individually. See: Rev. 1.57 and Rev. 1.58 (I also referred an email entitled "kern/94056:[PATCH] ..." in freebsd-bugs ML)

My machine HP Compaq nx 4300 also requires this.
