First and second channel bridge amplifiers are dynamically configured to drive either speakers or headphones. The first channel bridge amplifier includes a first amplifier driving one end of a first speaker through a mechanical switch in a headphone-jack, and a second amplifier driving another end of the first speaker. The second channel bridge amplifier includes third and fourth amplifiers driving respective ends of a second speaker. To suppress click and pop, an amplifier control circuit maintains certain amplifiers (depending on headphone or speaker mode) tri-stated until input coupling capacitors have fully charged and an input signal exceeding a predetermined amount is detected.
