    • An audio subsystem in a mobile communication device has a speaker. In one implementation, the audio subsystem has a higher-gain power amplifier, a lower-gain power amplifier, and a switching system configured to route signals produced by the lower-gain power amplifier to the speaker while the device is operative in a first mode and configured to route signals produced by the higher-gain power amplifier to the speaker while the device is operative in a second mode. In another implementation, the audio subsystem has a power amplifier coupled to the speaker and a power supply control controlled to provide voltage at a first voltage level to the power amplifier while the device is operative in a first mode and controlled to provide voltage at a second, higher, voltage level to the power amplifier while the device is operative in a second mode.
