# Audio problems

> Fix silence, missing program audio, mono or reversed stereo, echo, feedback, and dropouts.

## Connected but the send meter is silent

The problem is before the relay.

1. Select the intended microphone or vocal source in the dock.
2. Confirm that source exists in OBS.
3. Confirm it is not muted.
4. Speak and watch its OBS meter.
5. Select **Refresh** if the source was created after the dock opened.
6. Confirm another application has not taken exclusive control of the device.

## Send meter moves but the host receives nothing

* Confirm both docks still show the same live room.
* Confirm the guest key was accepted rather than only pasted.
* Check receiver or participant status.
* End and recreate the room if transport state is stale.
* Test on another trusted network if a firewall may block the relay.

## Incoming meter moves but the audience hears nothing

The network path works; inspect OBS:

1. Confirm the incoming or combined source is in the current scene.
2. Confirm the source is not muted.
3. Confirm the correct audio track is selected for the stream or recording.
4. Confirm the source fader is not at zero.
5. Make a local recording to distinguish monitoring from program output.

## Unexpected echo or delayed self-voice

Echo means the same audio has more than one path.

* Keep incoming vAudioLink sources on **Monitor Off**.
* Check whether Discord or another call application is also captured.
* Use headphones.
* In Music Collab, keep the backing monitor out of the program mix.
* In Scene Share, do not add the received audio separately.

Follow the full [audio routing guide](/guides/audio-routing).

## Feedback or loud howl

Immediately mute the incoming path or lower the physical monitor output. Then break the speaker-to-microphone or monitor-to-send loop. Do not continue by merely reducing gain.

## ASMR arrives in mono

* Confirm the physical microphone is configured as stereo.
* Confirm the selected OBS source preserves two channels.
* Confirm the dock's stereo option or quality mode does not intentionally downmix.
* Record the source locally before the network path.
* Compare local left/right meters with the host's incoming meters.

## Left and right are reversed

1. Test the microphone locally.
2. Run a clear physical left then right test.
3. Use **Send L/R test** where available.
4. Check whether an OBS filter, interface mixer, or cable adapter swaps channels.
5. Correct the earliest incorrect stage rather than swapping the final program as a workaround.

## Audio drops out or sounds unstable

* Prefer wired Ethernet.
* Stop large uploads and downloads.
* Disable route-changing VPN behavior during the session.
* Select a closer healthy relay.
* Reduce the configured quality or bitrate one step and retest.
* Preserve the OBS log and exact time of a dropout.
