ThinkSmart Hub User Guide
Solution
• If you are using powered external speakers that have an On/Off
control, ensure that:
– The On/Off control is set to the On position.
– The speaker power cable is connected to a properly grounded,
functional ac electrical outlet.
• If your external speakers have a volume control, ensure that the
volume is not set too low.
• Click the volume icon in the Windows notification area on the
taskbar. Check the speaker and volume settings. Do not mute the
speaker or set the volume at a very low level.
• Ensure that your external speakers (and headphones, if used) are
connected to the correct audio connector on the hub. Most
speaker cables are color-coded to match the audio connector.
Note: When external-speaker or headphone cables are connected
to the audio connector, the internal speaker, if present, is disabled.
In most cases, if an audio adapter is installed in one of the
expansion slots, the audio function built into the system board is
disabled. Therefore, you must use the audio connectors on the
audio adapter.
• Ensure that the audio device is configured as default speaker.
• Ensure that the audio device drivers are correctly installed.
Select the headset or headphones as the default audio output device
in settings.
Solution
• Ensure that all storage drive signal cables and power cables are
connected correctly.
• Ensure that the storage drive the hub starts up from is listed as the
first startup device in the UEFI BIOS. Refer to "Change the startup
sequence" on page 15.
Note: In rare cases, the storage drive with the operating system
might get corrupted or damaged. In such cases, you might need to
replace the storage drive.
