Fingerprint Reader Problems - Lenovo ThinkPad E485 User Manual

Solution: The slider might be grayed out. This means that its position is fixed by the hardware and cannot
be changed.
• Problem: The volume sliders do not stay in place when some audio programs are used.
Solution: It is normal for the sliders to change position when certain sound programs are used. The
programs are aware of the settings in the Volume Mixer window and are enabled to change the settings
themselves. An example is the Windows Media Player program. Usually the program has sliders available
to control the sound from within the program.
• Problem: The balance slider cannot completely mute one channel.
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 I 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 Speaker/HP.
• Problem: When I connect headphones to my computer while playing sound, a speaker does not produce
sound.
Solution: When the headphones are attached, the streaming is automatically redirected to it. If you want
to listen to sound from the speakers again, ensure that you set those speakers as the default device. For
more information, see the help information system for Conexant HD Audio Manager.
• Problem: Sound does not come from a headphone or a speaker, or the computer cannot record sounds.
Solution: To switch from one device to another (for example, from a speaker to a headphone, or from an
external microphone to a built-in microphone), do the following:
1. Go to Control Panel, and ensure that you view Control Panel by Category.
2. Click Hardware and Sound.
3. Click the Sound icon. The Sound window is displayed.
4. Click the Playback tab. Select the desired device (for example, speakers) and then click Set Default.
The speakers are set to the default device with a check mark displayed beside the speaker icon.
5. Play any sound through a music program (for example, Windows Media Player). Ensure that sound
comes from the speakers now.
6. Then, if you would like to switch to a headset, close the music program.
7. Click the Playback tab. Select Headset Earphone and then click Set Default. The headset is set to
the default device with a check mark displayed beside the headset icon.
8. Play any sound through a music program. Ensure that sound comes from the headset attached
directly to the computer.
