Black Y-splitter cable with one 9-pin male plug and two female sockets

SMUGDESK

SMUGDESK 9Pin HD Audio Y Splitter Cable 1to2

SKU CH-TRQD-M8AZV

Internal Y-cable splits one 9-pin HDAudio header into two front-panel audio ports with locking connectors

  • Turns one motherboard 9pin header into two front-panel audio ports
  • Locking clip on the male plug prevents loose connections from vibration
  • Works with standard HDAudio pin layout for headphone and microphone signals
  • Designed for inside-chassis wiring in PC builds and case swaps
  • Plug-and-play installation requires no drivers or extra software

Single-header expansion

This SMUGDESK Y-splitter converts one motherboard 9pin HDAUDIO male header into two female ports so a case with dual front-panel audio modules can connect both simultaneously. It follows the standard HDAudio pin assignment to carry microphone input and headphone output signals without driver installation. A built-in locking clip on the male plug secures the connection against vibration or movement inside the chassis. The cable is designed for internal wiring during PC builds, case swaps or hardware modifications.

Replaces header shortage

It solves the mismatch when a motherboard provides only a single HDAUDIO header but the chassis front panel includes two separate audio harnesses. The upgrade is worth it when rebuilding into a case that offers dual headphone and microphone jacks or when adding a second front-panel audio module to an existing system. It cannot function with older AC97 headers because the pin layout differs, so boards limited to that legacy interface remain incompatible.

Dual-port headroom

The splitter comfortably handles two standard front-panel audio harnesses carrying analog stereo output and mono microphone input. It runs out when the motherboard header itself lacks sufficient drive current for both connected modules simultaneously or when the case wiring uses a non-standard pinout that deviates from the HDAudio specification.

Questions about this item

Will the male 9-pin HDAudio header on my motherboard accept the splitter's locking clip?

The male plug has a built-in retention clip that clicks onto a standard 9-pin HDAudio header, holding it firmly against chassis vibration.

Which step do builders most often skip when connecting two front-panel audio harnesses?

After plugging the male end into the motherboard header, both front-panel harnesses must be seated fully into the two female ports; a loose harness causes static or cut-out.

How do I know when the Y-splitter itself needs replacing?

If audio drops out or crackles only when the case is moved, the locking clip or internal contacts have worn and the cable should be swapped.
