Audio Test Group - Dell Inspiron 3500 Reference And Troubleshooting Manual

After you eliminate incorrect system configuration information settings, peripheral
malfunctions, and software errors as potential causes of port problems, you can run
the subtests in the Parallel Ports test group to check your hardware. Although the
following symptoms can be caused by faulty peripherals or software errors, they
might also suggest a port problem:
‡
If a peripheral works intermittently, or produces intermittent errors, the port may
be faulty.
‡
If the computer displays an error message that is related to the external device
connected to a port, but corrections to the device do not resolve the error, run the
appropriate subtest in the Parallel Ports test group.
‡
If your software and the diagnostics do not recognize that you have a parallel
port, you should check the Parallel Port option in the System Devices menu of
the Setup program, and if necessary, run the appropriate subtest in the Parallel
Ports test group.

The three subtests in the Parallel Ports test group confirm the following port
functions:
‡
Parallel Internal Test
Checks several internal functions of the parallel port.
‡
Parallel External Interrupt Test
Tests the parallel port's ability to generate interrupts from all possible sources, if
an external loopback connector is available.
‡
Parallel Printer Pattern Test
Tests whether the port(s) can retain data, print text on a printer, and generate
interrupts.

The subtests in the Audio test group check the functions of the audio controller and
the computer's recording and playback features.

If you do not hear sounds from your built-in speakers when you expect to, it is possi-
ble that your operating system or sound application uses resource settings different
than those of the audio controller in the computer. In the absence of an expected
sound, first check the documentation that accompanied your operating system or
sound application to see if the sound features are correctly configured to work with
the computer. The default resource settings for the audio controller are:
‡
DMA channel: 1
‡
IRQ line: 5
‡
Port address: 220h
