Microphone on the HTC VIVE Focus 3 doesn't work
Microphone on the HTC VIVE Focus 3 doesn't work, but on other platforms -Pico, Oculus, PC everything's ok. What could be the problem?
KHi @MaxEsin. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. 
K----------------------
I'm sorry, but the knowledge sources do not contain specific information about microphone support or known issues on the HTC VIVE Focus 3 platform. The documentation covers microphone setup and troubleshooting for platforms like Mac, iOS, Android, and general Unity settings, but does not mention the VIVE Focus 3 or provide platform-specific guidance for it.
If the microphone works on Pico, Oculus, and PC but not on the VIVE Focus 3, it may be due to platform-specific compatibility or permission issues not addressed in the current Normcore documentation. I recommend checking your Unity microphone permissions and device settings, as well as reaching out to the Normcore community for further assistance, as suggested in the documentation for unresolved issuesVoice chat common questions.

Note: you can ask me a follow up question by @ mentioning me again

K@328247194794852352 Kapa.ai is still learning and improving, please let me know how I did by reacting below.
MOn the Vive Focus 3, Normcore uses the Unity Microphone API. I would start by verifying that the Unity microphone API works on that platform. HTC has been known to be fairly buggy there
MAlso make sure nothing else in your app tries to bind to the microphone too. Unity’s microphone API will return silence for all future attempts to bind to the microphone
MThanks for reply! Okey, I'll check it
MSo, I debugged the connection to the room and catch next error :
AndroidPlayer "HTC_VIVE_Focus_3" GameObject has multiple AudioSources and/or AudioListeners attached. While built-in filters like lowpass are instantiated separately, components implementing OnAudioFilterRead may only be used by either one AudioSource or AudioListener at a time.
The reason for this is that any state information used by the callback exists only once in the component, and the source or listener calling it cannot be inferred from the callback.
In this case the OnAudioFilterRead callback of script AudioPreprocessorPlaybackListener was first attached to a component of type AudioSource on the game object Camera after which a component of type AudioListener tried to attach it.
UnityEngine.GameObject:AddComponent()
Normal.Realtime.RealtimeAvatarVoice:ConnectLocalAudioStream()
Normal.Realtime.<RequestMicrophonePermissionAndConnectLocalAudioStreamTask>d__36:MoveNext()
UnityEngine.SetupCoroutine:InvokeMoveNext(IEnumerator, IntPtr)
Normal.Realtime.RealtimeAvatarVoice:RequestMicrophonePermissionAndConnectLocalAudioStream()
Normal.Realtime.RealtimeAvatarVoice:ConnectAudioStream()
Normal.Realtime.RealtimeAvatarVoice:Update()
[./Modules/Audio/Public/AudioCustomFilter.cpp line -1521741816]
I guess the line 287 in the attached image throws the error. The script is RealtimeAvatarVoice. SDK version 2.15.4. What could be the solution to it?

Mcan you show me the logic for how the echoCancellation book is calculated and what each of the values log on that device? it should evaluate to false on that platform as it has hardware echo cancellation already
MThanks for helping me out 
Well, here it is. Hope it's what you asked!
Well, here it is. Hope it's what you asked!
M@NormalMark any chance you can add the loadedDeviceName from this to the echo cancellation exclusion list in RealtimeAvatarVoice?
Nwill do 
Min the meantime @MaxEsin I’d fork RealtimeAvatarVoice to set echoCancellation to false
M@MaxEsin This is fixed in https://discord.com/channels/393839515074297858/852911447784947723/1372989781927006309
MGive it a shot and let us know how it works out for you
M@maxweisel Well, I've forked like you suggested with include of "wvr" string in the list of "isXRPlatform" variable set. The error is gone but the microphone still didn't work properly. I've found the post from liamc and added that check in the forked RealtimeAvatarVoice component. The microphone become pretty stable
M@MaxEsin did you try the normcore version I linked? we shipped a fix
MNo, I didn't. I tried only my forked version. The changes I've made are in the attached image and the coroutine check from the previous message
