Your patient not being able to hear you can be due to several reasons. 

First, run doxybot pre-call test on your device to make sure your microphone is set up and working. 

Also have your patient doxybot pre-call test to make sure their speakers are working. Send this link to your patient: https://doxy.me/precall-test

Here are a few things to try:

Refresh your browsers
Sometimes your browser doesn't connect to your microphone or their speakers properly. Restart both your browsers to give it another chance to connect properly. 

Are their speakers turned on?
Make sure your patient can hear sound from their speakers. If they have headphones or other speakers connected, make sure the sound isn't playing there. To confirm that sound is working, have them play this video.

Do you have a microphone?
Your computer may not have a microphone, or it's not plugged in or turned on. Check to make sure you have a working microphone.

Is your microphone muted?
If you have a microphone with a press-to-mute button, make sure it isn't muted. Also, Doxy.me has its own mute button. Make sure you don't have it on. 

Did you give permission to access your microphone?
The first time you log in to doxy.me, your browser will request permission to access your microphone. If you denied access, they won't hear you.

Restart both your computers
Sometimes other video conference software (such as Skype, FaceTime) can block access to your microphone or speakers. Restart both of your computers, then try again.

Is your browser up to date?
Out of date browsers can cause audio issues. Make sure your browser is on the latest version. 

Change browsers
If your current browsers are not working, try using different browsers.

Check your computer settings
Your computer settings may prevent you from sharing your microphone.  Check your microphone computer settings on Windows or Mac. 

Check antivirus, firewall or parental settings
You may have antivirus, firewall, or parental control software installed that is blocking access to your microphone.
