"3D Alpha" is a generic branding used by multiple manufacturers. I cannot confirm compatibility without the exact model number.
| Issue | Cause | Fix |
|---|---|---|
| No audio | Headset requires Windows driver for DSP/surround | Try stereo mode; check PS3 audio output settings |
| Mic not detected | Combo 3.5mm jack + USB adapter not wired for mic | Use native USB headset or PS3-certified model |
| Static/buzzing | Ground loop / poor shielding | Ferrite core on cable; different USB port |
| Surround not working | PS3 outputs 5.1/7.1 LPCM; headset DSP expects Dolby/DTS | Set PS3 audio to "Linear PCM 5.1/7.1ch" |
