Okay folks, this is a weird one and to be honest I don't really expect anyone to be able to solve this problem as I've already been through all kinds of attempted fixes with Official Xbox Phone Support. I'm creating this thread to describe my set-up, explain the issue, symptoms/elaboration/observations, testing and reproduction, the attempted fixes and to see what percentage of the community might also be experiencing the issue as I've seen it mentioned by four other people besides myself.
- Xbox 360 Elite - Manufacture Date 2008/05/02
- 120GB HDD
- Official Xbox 360 Wired Controller
- Official Xbox 360 Wired Headset
- Wired Internet Connection
- HDMI Connection to TV
- When people speak while I'm in Party Chat it causes both left and right thumbsticks to register downward/right inputs as if they are tapped downward/right
- Has been happening for an undetermined length of time through several controller replacements
- First noticed while playing Minecraft, while controller was at rest saw "twitching" of game character
- "Twitching" is a step backwards/right and/or one to two degree turn to the right of game character/character dodging/rolling
- Also noticed while playing Borderlands 2, same type of "twitching" while controller is at rest
- While playing Diablo 3 game character will turn from facing north to south and/or roll downwards
- In Diablo 3 Pause menu, cursor will cycle through menu options
- Wasn't until playing Diablo 3 that I made the connection between being in Party Chat and people speaking in chat causing the "twitching"
- Happens with members in Party Chat using all mic types although Third party mics seem to trigger it more often
- Third party mics seem to pickup and transmit more sound than Official Xbox mics, possible correlation
- Stops occurring while still in Party Chat if headset jack is disconnected from controller
- Have been unable to check if it continues to occur in regular Game Chat
- Varying degree of sensitivity in each title to Party Chat speech
- Sensitivity seems to relate to the thumbstick deadzone of the individual titles
- Borderlands 2 thumbstick deadzone is "large," least affected game, very subtle "twitching"
- Minecraft thumbstick deadzone is "medium," noticeable "twitching"
- Diablo 3 thumbstick deadzone is extremely "small," obvious "twitching"
Testing and Reproduction
- Enter Party Chat
- Minecraft, line up crosshairs on an object with a perpendicular angle, place controller at rest
- Borderlands 2, line up crosshairs on an object with a perpendicular angle, place controller at rest
- Ask Party Chat members to speak
- Causes character to 'twitch" backwards visibly, also distinguishable by crosshairs no longer being lined up with orientation object
- Diablo 3, load game, character in game world, place controller at rest
- Ask Party Chat members to speak,
- Causes character to rotate from facing "north" to "south" and or Dodge/Roll downwards/right or "southeast"
- Disconnect headset jack while in Party Chat
- Message Party Chat members to speak
- Can hear Party Chat members speaking through audio system
- No noticeable character movement or "twitching" occurs
- Plug headset back in, "twitching" resumes
- Deleting and re-downloading Profile
- Cleared system cache three time
- Deleted console updates
- Deleted Marketplace cache
- Adjusting Game Defaults in Profile section of Settings, both General and Action
