Check 10: Is the audio circuit OK?
<Outline> The serial 3 lines digital DACCLK, output from DVD-LSI (IC1501), are converted to analog audio
signal at Audio-DAC (IC1801) and are output from the HOST I/F (CN1901).
Simultaneously, the analog MUTE signal is also output from DVD-LSI (IC1501) via the HOST I/F.
The digital audio signal (IECOUT), output from DVD-LSI (IC1501), is output via CN1852.
