Audio interface
In order to reduce the space dedicated to connectors, SBC-992-pITX board doesn
’
t offer any
standard audio jack.
However, SBC-992-pITX integrates a High Definition Audio Codec, Realtek
ALC886GR, that makes basic audio connection available on dedicated
connector CN19, which is a 9-pin pin header, p2.54 mm h= 6mm, type
NELTRON p/n 2213S-10G-E8 or equivalent, with the pinout shown in the table on the left.
The pinout of this connector complies with Intel
®
Front Panel I/O connectivity Design Guide,
High Definition Audio section, chapter 2.5.
Using this dedicated connector, it will be possible to connect any Azalia compliant panel
audio jack to remote audio connectors in the preferred position.
Alternatively, it is also possible to buy SECO
’
s dedicated front panel module, which offers two standard audio jacks, two pushbuttons (for reset and power on) and
two LEDs, for SATA activity and Power status signalling.
This adapter module is also contained inside the dedicated accessories kit p/n CABKIT992 for SBC-992-pITX board. Please also check chapter 5.2.1 for further
details.
