# Audio/Video Troubleshooting
If you're having trouble with your audio or video, this is the place.
## Other's can't hear me
#### Check that your microphone is enabled in the browser:
####
#### Check your systems settings:
{% tabs %}
{% tab title="Windows" %}
Make sure the correct input device is selected, the volume is turned up, and you receive visible feedback (the volume bar moves) when you speak.
{% endtab %}
{% tab title="Mac" %}
Open your system preferences and select "Sound":
Make sure the correct input device is selected. It's usually your "Internal Microphone":
{% endtab %}
{% endtabs %}
#### Did you plug in a headset with a mic? If so, try refreshing Yaatly. If that does not work, try unplugging your headset then refreshing Yaatly.
## I can't hear others
1. Make sure that your computer volume is turned up.
2. Did you plug in a headset after you joined the room? If so try refreshing Yaatly.
3. Check your system settings:
{% tabs %}
{% tab title="Windows" %}
Make sure the correct output is selected:
\
\
{% endtab %}
{% tab title="Mac" %}
Open your system preferences and select "Sound":
Make sure the correct output device is selected. It's usually your "Internal Microphone". Also make sure you are not muted.
{% endtab %}
{% endtabs %}
## Others can't see me
#### Check that your camera is enabled in the browser:
#### Check your system settings:
{% tabs %}
{% tab title="Windows" %}
{% endtab %}
{% tab title="Mac" %}
Open your System Preferences and click on Security & Privacy:
Now check that your camera is allowed for the browser you use with Yaatly:
{% endtab %}
{% endtabs %}
## When I join a room, I can't see or hear anything
Make sure you are using either Chrome or Internet Edge. Firefox has a known issue with audio, and Safari does not work.
## I keep seeing this: \`FirebaseError: \[code=unavailable]: Failed to get document because the client is offline.\`
Make sure you do not have parental control software enabled. Or, add Yaatly as a safe site to your software and/or Firewall.
## Yaatly is not working
If you are unable to access the site, please make sure you do not have an HTML or Javascript blocker enabled.
