There are two audio streams in a Session, and they fail for different reasons. Work out which one is silent first:

• Talkback is people's voices. If you can't hear someone talking, start with Talkback below.
• HQ Audio is the music from someone's DAW. If you can hear them talk but not their playback, go to HQ Audio.

You can't hear someone's Talkback

1. Open the Mixer and watch their Talkback meter while they speak. If it doesn't move, the problem is on their side: their microphone isn't selected, or their computer is blocking it. Send them Allow camera and microphone access on Mac and Windows.
2. If their meter moves, check your own speakers. Click the arrow next to Talkback in your Studio and make sure the output is the speakers or headphones you're actually listening on.
3. If you're on Safari or Firefox, switch to Chrome, Edge, Brave, Opera or Arc, or the Sessionwire app. Those two browsers aren't supported.

You can't hear someone's HQ Audio

1. If they're your Guest, turn their HQ Audio on. Guests can hear your HQ Audio straight away, but they can't send theirs until the Host turns it on. Click Mixer, then click the Sessionwire wire icon above their stereo meters. This is the most common reason a Host can't hear a Guest's DAW.
2. Watch their HQ Audio meters while they press play. If nothing moves, the problem is on their side. Their HQ Audio Source needs to be set to the Sessionwire Send Plugin, and the Send plugin needs to be on the output they're playing through, usually the main stereo out.
3. If their meters move, check your HQ Audio Destination. It should be the speakers or headphones you're listening on.
4. If you're recording them in your DAW, put the Sessionwire Receive Plugin on a stereo track and set HQ Audio Destination to it. Check step 1 first. Most "the Receive plugin isn't getting anything" problems are a Guest whose HQ Audio hasn't been turned on.

Still nothing

• Leave the Session, close Sessionwire or the browser tab completely, and join again.
• On a Mac, open Audio MIDI Setup (Applications > Utilities) and check each Sessionwire driver is set to 48,000 Hz and 32-bit float. If the drivers are missing, see Sessionwire drivers or plugins not showing up.
• On Windows, check the Sessionwire devices are enabled and exclusive mode is off. See Set up Sessionwire on Windows.
• With Pro Tools on Avid hardware, Pro Tools takes over the Avid drivers, so Talkback has to go through Pro Tools with the Talkback Send and Talkback Receive plugins.

If it still doesn't work, email support@sessionwire.com. Tell us your computer and operating system, whether you're in the app or a browser, and which stream is silent. A screenshot of your HQ Audio menu while you're playing helps a lot.
