NOTE: The following subtests are only applicable for systems with built-in speakers.
The eleven subtests in the Audio Test Group confirm the following functions:
Software Reset Test
Checks for the presence of an active audio controller in your system
Compatibility ID Test
Determines if the correct sound controller is installed in your system
Interrupt Test
Checks to see if the audio controller is generating an interrupt on the IRQ line configured for that
controller
DMA Test
Tests for the presence of a DMA channel on the system chip set, and determines if the DMA
controller and audio controller can exchange signals
FIFO RAM Test
Checks the read/write capabilities and status of the audio controller
Initial Reset Status Test
Verifies the reset values of the extended registers on the audio controller
Internal Register Test
Writes test patterns to the internal registers of the audio controller, then reads other registers to
confirm that the patterns are correctly interpreted
Dual Channel Test
Confirms the presence of a second DMA channel on the system chip set and determines if the
DMA controller and audio controller can exchange signals on that second DMA channel
FM Sound Playback Test
Tests whether the system can synthesize sounds and play them through the built-in speakers
Analog Sound Playback Test
Tests whether the system can play sampled sounds through the built-in speakers
Record and Playback Test
Checks the ability of the audio controller to generate a sampled sound from signals received from
the built-in microphone
