Lenovo ThinkPad 11e Chromebook - Manual (Page 50)

Solution: The control is designed to compensate for minor differences in balance and does not
completely mute either channel.
• Problem: There is no volume control for MIDI sound in the Volume Mixer window.
Solution: Use the hardware volume control. This is because the built-in synthesizer software does
not support the control.
• Problem: The sound cannot be turned off even if you set the Master volume control at minimum.
Solution: You still can hear some sound even though you have set the Master volume control at minimum.
To turn off the sound completely, go to the Master volume control and select Mute speakers.
• Problem: When you connect a headphone to your computer while playing sound, a speaker does not
produce sound.
Solution: Once the headphone is attached, the streaming is automatically redirected to it. If you want to
listen to sound from the speakers again, be sure to set those speakers as the default device.
