No Speaker Output; Sound Cannot Be Recorded - Ctl 2GO Classmate PC User Manual

•
Be sure all the device drivers are installed properly. For
example, without the audio driver properly installed, the
speakers and microphone will not work.
•
If external devices such as USB camera, scanner or printer do
not function correctly when connected to the system, it is
usually the device's own problem. Consult the device's
manufacturer first.
•
Some software programs, which have not gone through
rigorous coding and testing, may cause problems during your
routine use. Consult the software vendor for problem solving.
•
Be sure to go to BIOS SETUP and load DEFAULT SETTING
after BIOS re-flash.
Audio Problems

No speaker output

•
Software volume control is turned down in Operating System's
Sound System or is muted. Double-click the speaker icon on
the lower right corner of the taskbar to see if the speaker has
been muted or turned down all the way.
•
Most audio problems are software-related. If your computer
worked before, chances are software may have been set
incorrectly.

Sound cannot be recorded

•
Double-click the speaker icon on the lower right corner of the
taskbar to see if the microphone has been muted.

Click Options and select Properties.
•
Select Recording and click the OK button.

Hard Disk (Optional) Problems
The hard disk drive does not work or is not recognizable:
•
If you had just performed a hard disk upgrade, make sure the
hard drive connector is not loose and the hard disk drive is also
correctly seated. Remove it and reinsert it firmly, and restart
your PC. (Refer to Chapter 5 for details.)
•
The new HDD may need to be partitioned and reformatted. O/S
and drivers will need to be re-installed as well.
