Frequently asked questions
I hear nothing at all.
Check that the device isn't muted, that no other app is holding the audio, and that sound isn't going to a Bluetooth device.
Left and right sound the same on my phone.
Phone speakers are often close together or there's only one. Headphones let you tell them apart.
Can I test my microphone here?
