• Manufacturer Part Number: alc268
• Description: 2+2 Channel High Definition Audio Codec
• Manufacturer: Realtek Semiconductor Corporation

As the ALC268 series does not support LINE2 (port-E) or HP-OUT (port-A), these pins may be
connected to the front panel header as the headphone output. To accommodate the ALC268 series and
ALC262 series on the same front panel I/O cable, the connection of the front panel header in Figure 21 is
modified. Please contact Realtek to confirm your design can accommodate all ALC series HD Audio
Codecs.
