• The wrong audio mode might be selected in GoToTraining. – When you are in a session, you are able to specify which audio mode you use to connect to the audio conference (depending on which modes the organizer made available). It's possible that the default mode you joined with is not the one you want, and that you need to manually switch it.
  • If you want to connect with your mic and speakers, make sure Computer Mode or Internet Mode is selected.
  • If you want to connect with your telephone, make sure Phone Mode is selected.
• The session might already be over. – If it looks like the session is running but no one responds to your chat messages, it's possible that you joined late and the organizer accidentally left the session running! Check the start time of the session and make sure it wasn't supposed to start earlier in the day, particularly if there is a time zone difference for you and the organizer.

Here are a few suggestions of what might be preventing you from hearing the other participants in the session.

• The volume of your speakers might be turned down too low. –Try turning up the volume gradually until you can hear something!
• There might be a problem with your telephone service provider. – If there is a problem with your telephone connection, it might be an issue with your service provider. We cannot provide troubleshooting support for your service provider, but we can suggest that you try connecting via mic and speakers instead.
• The organizer might not have provided Phone Mode as an option for the session. –While GoToTraining provides users with multiple options for connecting to the audio conference, it is up to the organizer to decide which audio modes are available in each session. See Why can't I connect to audio with my telephone? for more information.

• GoToTraining might be playing sound through a headset instead of speakers. – If you have a headset plugged into your computer or device but you are not currently wearing it, GoToTraining might be using it as your audio output device instead of your speakers. Either put on the headset, unplug the headset or see Test your Mic and Speakers (VoIP) to learn how to specify which device to use as speakers!
• You might not have any speakers plugged into your computer or device. – If you're sure you have speakers plugged into your computer, it's possible that GoToTraining hasn't detected them.
