The only exception I can think of is when
there's a
DC offset to the signal of sufficient voltage to force the
signal always be positive (or always negative).
But that would mean something's broken :)
Not necessarily broken. Class A amplifiers do their work
with sufficient DC offset that the signal never changes
direction. Even so, the music is carried by an AC
*component* which is present, and may be separated out by
using a transformer.
