No sound on laptop during playback

My Tablo quad is connected to modem wirelessly. Tried for first time playback on my HP laptop. All good, except no sound. Surround sound has been deselected in Tablo settings, and other settings checked. Suggestions?

Live TV or recorded content?

Are you using the web app in a browser or Windows 10 Tablo app?

Laptop has no sound live or recorded.
Using app I downloaded with Chrome browser on Win 10 laptop. Streaming to Roku and my TV works fine.

Try the Windows 10 Tablo app. You can get it from the Microsoft Store.
