12. Front Panel Audio header
This header is for a chassis-mounted front panel audio I/O module that
supports HD audio standard. Connect one end of the front panel audio I/O
module cable to this header.
We recommend that you connect a high-denition front panel audio
module to this header to avail of the motherboard’s high-denition
audio capability.
If you want to connect a high-denition front panel audio module to
this header, set the Front Panel Type item in the BIOS setup to [HD
Audio]. By default, this header is set to [HD Audio].
13. S/PDIF Out header

15. SPI TPM header
This header supports a Trusted Platform Module (TPM) system with a
Serial Peripheral Interface (SPI), allowing you to securely store keys, digital
certicates, passwords, and data. A TPM system also helps enhance network
security, protects digital identities, and ensures platform integrity.
