No Sound On Playback

I’ve been working on a scene for the last 2 weeks and now when I open it and press play, there is no playback of audio. It’s worked all this time and I’ve done no updates or anything that should change anything.

Does this happen after a reboot of the computer also?
Post a screenshot of the start of the audio column in the timeline.

Make sure “Audio Playback” is checked in the Play menu also
“Include Audio in Playback Range” just underneath helps.
