Toshiba A3X manual Sound Legacy test

3.30 Sound Test program		3 Tests and Diagnostics
Subtest02	Sine Wave
	This subtest is executed by loading the COM file (ADSIN.COM). The
	program expands sine wave data table from 16KB to 64KB, and creates the
	play data. Then it transfers the data between the DMA and the CODEC to
	play the sine wave. (It sounds like a continuous beep). By using wave
	measurable devices such as an oscilloscope, the data can be measured as a
	sine wave.
	When the subtest is executed, the sine wave is played while expanding sine
	wave from 16KB to 64KB.
	The display returns to the Sound (Standard) test menu after the test ends.
Subtest03	Line IN recording & play
	This subtest executes the same test as the subtest01 by recorded sound from
	the different port (Line-in port).

For more details on the subtest, refer to the subtest01 Microphone recording & play.

The display returns to the Sound (Standard) test menu after the test ends.
