GP7 - Audio Setup and Testing
Audio Setup, Testing and Tuning

GP7 uses Google WebRTC for audio. WebRTC receives its audio from the operating system (Windows, OSX, ChromeOS). Therefore, GP7 gets audio from the operating system not directly from the sound card. For this reason, USB headsets and speakers pretty much always work, and sometimes headsets that plug directly into the sound card (the round-end plugs) may not work well. GP7 lists all the audio devices it can access, so the user can specifically choose what audio device to use for listening ("Speaker") and speaking ("Microphone").

GP7 uses state-of-the-art STUN, TURN and ICE standards to find the fastest stable internet path between your computer and the audio server. Since routing paths are dependent on the user's geographical location, local network and (sometimes) even the specific computer, these network settings are also provided for the user to select the one that works best for his immediate context.

Optimize GP7 Audio

  1. If GP7 was already open, close GP7 completely and then open it (this resets GP7 internal components).
  2. Go to the Setup and Testing section on the Home view. Perform all three tests in order, without skipping any steps (later tests and steps depend on earlier tests and steps).
  3. Speaker Test
    1. Select the preferred speaker (usually headset speaker) from the drop-down. Run the Speaker test. If it passes, leave this option selected (do not leave the selection as Default or blank -- this may give inconsistent results from one session to the next) and go to the Mic Test.
    2. If the Speaker Test fails, select different speaker options from the drop-down until it passes with an option you can use for class, then go to the Mic Test.
      • If no speaker selections pass, try a USB headset (USB headsets pretty much always work unless there is some other problem outside the scope of GP7 audio settings).
      • If you are already using a USB headset, close GP7, unplug USB headset plug, wait 15 sec, plug USB back in, wait 15 sec, open GP7, and restart the Speaker Test.
      • If you you don't have a USB headset or the unplug/re-plug fails, reboot computer, open GP7, and restart the Speaker Test.
    3. If you cannot pass the Speaker Test after trying all of these steps, please visit TPS live support for further assistance.
  4. Mic Test
    1. Select the preferred mic (headset mic is required for TPS classes) from the drop-down. Run the Mic test. If it passes, leave this option selected (do not leave the selection as Default or blank -- this may give inconsistent results from one session to the next) and go to the Network Test.
    2. If the Mic Test fails, select different mic options from the drop-down until it passes with an option you can use for class, then go to the Network Test.
      • If no mic selections pass, try a USB headset (USB headsets pretty much always work unless there is some other problem outside the scope of GP7 audio settings).
      • If you are already using a USB headset, close GP7, unplug USB headset plug, wait 15 sec, plug USB back in, wait 15 sec, open GP7, and restart testing with the Speaker Test.
      • If you you don't have a USB headset or the unplug/re-plug fails, reboot computer, open GP7, and restart testing with the Speaker Test.
    3. If you cannot pass the Mic Test after trying all of these steps, please visit TPS live support for further assistance.
  5. Network Test
    1. The Network options are listed simplest to most complex. You should choose the simplest option that consistently connects most quickly for your current computer in your current location using your current wifi and internet. The time to connect is counted from when you click to start the Network Test to when you start to hear the audio (background music) in the test.
    2. Select each Network option from the drop-down, starting with the simplest one. If one connects instantly (within one second), leave it selected. You are ready for class.
      • If none connect instantly, test each of them and select the simplest option that consistently connects most quickly for your current computer in your current location using your current wifi and internet. (Wait up to one minute for each Network Test option to provide the audio (background music). The tests do a deep search for a best connection and may take up to one minute.)
      • If none connect at all, reboot your router and computer and and restart testing with the Speaker Test. If a router reboot does not resolve the problem, then most likely there is a firewall or parental controls block on your system. You will need to locate and remove the block.
    3. If you find yourself losing audio during class, return to GP7 Setup and select a different Network option to see if it works better for your current computer in your current location using your current wifi and internet.

When you pass all three tests with your current computer in your current location using your current wifi and internet, you are ready for class.

Loss of Audio During Class

GP7 uses state-of-the-art STUN, TURN and ICE standards to find the fastest stable internet path between your computer and the audio server. If GP7 loses that audio connection during a meeting, it will usually regain it on its own (usually you won't even notice any loss). However, if you lose audio for more than 15-30 sec, it is likely that audio cannot be restored automatically, and you should try to restore it manually.

If you are in a meeting with good audio and then lose your individual audio, please try each of the following until your audio is restored:
  1. Leave the meeting, close/quit GP7, re-open GP7, and rejoin the meeting.
  2. If you still have trouble, please follow the Optimize GP7 Audio steps above.

Audio Cuts In and Out During Class

Audio that cuts in and out on its own indicates a weak or unstable network connection. Please try each of the following until your audio is solid:
  1. If you are using wifi, move closer to the wifi signal source until you have a strong stable signal.
  2. Leave the meeting, close/quit GP7, re-open GP7, and rejoin the meeting.
  3. Perform the Optimize GP7 Audio steps above, and try a different Network selection from the drop-down.
  4. Restart your router and reboot your computer.
  5. If you are using wifi, try connecting directly to the router with an ethernet cable.
  6. If none of these work, please contact TPS Support and give us details about the type of internet you use (cable, fiberoptic, DSL, mobile broadband, satellite, etc.) so we can help you optimize your connection.
