3 Tests and Diagnostics 3.29 Sound Test program Subtest 02 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. Subtest 03 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. 3.29.2 Sound (Legacy) test To execute the Sound (Legacy) test, select 2 and press Enter.
