| Problem | Likely Fix | |---------|-------------| | No game audio on Xbox | Must use optical cable. USB alone = chat only. | | Mic not working on PC | Set Mixamp as “Default Communication Device” in Windows sound settings. | | Game/voice dial does nothing | Press in the dial to “lock” it – then rotate. LED will indicate mode. | | Dolby button no effect | Dolby only works with optical input. Over USB (PC), it’s stereo only. | | No stream port audio | Open Astro Command Center → Stream Port tab → set to “Game + Aux + Mic” or custom mix. |
