Troubleshooting Video Conferencing Audio

I am getting echo in VoIP audio. What can I do?

1. Check to make sure your microphone is away from your speakers. If needed, ask your participants to do the same.
2. You may be getting a feedback loop. Try turning down your microphone sensitivity; it may be picking up your participants, including participants sitting nearby or participants heard over the Internet. Right click your name on the participant list, select Audio Settings, and lower Recording Volume. If db Boost is selected, try deselecting it.
3. The wrong microphone may be selected. Right click your name on the participant list, select Audio Settings, and confirm the correct microphone is selected. Mixing up microphones occurs frequently, especially after webcams and other peripherals are installed. They often change your audio device preferences.
4. For best results, use a headset or echo cancelling speakerphone. Depending on your choice of audio peripheral, try experimenting with the OmniJoin Acoustic Echo Cancellation feature. Right click your name on the participant list, select Audio Settings, and select/deselect Acoustic Echo Cancellation.

My voice is not getting transmitted to the other party's side. What should I do?

Check the following:

1. Make sure your microphone and your participant's speakers are plugged in correctly and powered on. Details: How do I check and confirm the microphone is accessible to OmniJoin? And How do I check if the speaker is plugged in correctly?
2. Verify that your microphone is not accidentally muted (hardware). This happens frequently with USB headsets with ticky mute buttons.
3. Verify that your microphone is not accidentally muted by OmniJoin (software). Check your name on the participant list, the microphone icon should NOT be grayed out. If it is greyed-out, right click your name and select Unmute. There is also Mute checkbox in the lower right-hand corner for quicker access; make sure it is NOT selected.

My microphone volume is very low. What can I do?

Check the following:

1. While in a meeting, select [Audio] tab and use the slider for microphone and adjust the volume.
2. If the headset or speaker phone itself has volume adjustment function, try adjusting this to a higher level.
3. Try adjusting the volume from Windows® volume control. To do this, see the following steps:

Windows Vista®/ Windows® 7
3-1. Right-click on the speaker icon in the system tray and open [Recording Device].
3-2. Double-click the microphone and open the [Microphone property].
3-3. Use the slider and adjust the volume.

Windows Vista®/ Windows® 7
4-1. Right-click on the speaker icon in the system tray and open [Recording Device].
4-2. Double-click the microphone and open the [Microphone property].
4-3. Select the [Level] tab and use the slider and adjust "+24.0 db" (for example) and click [OK].

I am getting "choppy" sound. What should I do?

Check the following:

1. Check if the microphone on your side or the speaker on the other party's side is plugged in correctly. For more information, click How do I check and confirm the microphone is accessible to OmniJoin? and How do I check if the speaker is plugged in correctly?.
2. Check your 5-bar Connection Rating in the lower right-hand corner. Mouse over the five-bar rating for latency details, connection with extremely high latency may create audio issues.
3. Disable the echo canceller or noise reduction software, if you selected these options.
4. Extreme packet loss may have occurred (e.g., an intermittent wireless connection or a poor IP route). You can try to establish a better connection by closing OmniJoin and re-entering your meeting. Do not forcibly close OmniJoin (i.e., with task manager), as then you will have to wait a few minutes to re-enter your conference room (the OmniJoin cloud is still awaiting status on your old connection).

I can't hear anything. What can I do?

See the following:
1. Check if the speaker is plugged in correctly. For more information, click How to check if the speaker is plugged in correctly.
2. Make sure the speaker power switch is on.
3. Check if the speaker is working. For more information, click How do I check if the speaker is working properly?

There is noticeable "howling" in the audio transmission. What should I do?

See the following:

1. Keep the microphone away from the speaker.
2. Turn down the volume of the microphone or speaker.
3. Try using the speaker in your headset or use a speakerphone with echo cancellation.

There is a delay in the audio transmission. What should I do?

Check the following:

1. Check the system requirements. If you don't meet the system requirements, OmniJoin may not work well. For more information, click System Requirements.
2. Confirm that your computer is connected to the Internet.
3. Check your 5-bar Connection Rating in the lower right-hand corner. Mouse over the display for network latency details. Extremely high latency may create audio issues.
4. Check your Internet connection rating. Heavy bandwidth consumption may have "maxed-out" all available resources. For more information, click Can I check my Internet connection rating? and Can I check how much bandwidth I am using?.

NOTE: Your connection rating is more important; OmniJoin may not be using much bandwidth because it is not available!
5. A system error may have occurred. Restart OmniJoin.
