Play a sound on its card

A sound's card in BaseHalf has a player. Play starts the file with its sound. I listened to a short spoken closing checklist on the card and wrote the two steps in a note.

I needed the two Saturday closing steps written down, so the evening shift could see them without playing the file. I had saved them as a short spoken checklist, closing-checklist.m4a, in the same folder as a Saturday closing note.

I opened the folder in BaseHalf 0.7.0. The sound card keeps the size of a file card, not the shape of a picture. A speaker mark sits by the file name, and a simple waveform sits on the face of the card.

A BaseHalf canvas titled 2026-11-15-pm-sound-player, with a closing-checklist.m4a sound card beside a Saturday closing note that asks for the two steps to be written down.

A sound's card has a player. When I pointed at the card, the controls appeared: Play, a Position slider at 0.0s of 6.0s, and Open. There is no Mute control on a sound card.

The closing-checklist.m4a card with its player visible: Play, a Position slider at 0.0s of 6.0s, and Open, plus a waveform on the face of the card.

I clicked Play. The checklist played with its sound. The control became Pause, and the position showed 1.3s of 6.0s. Pointing at the card does not start playback. Play does.

The same sound card playing, with Pause and the Position slider at 1.3s of 6.0s.

I clicked an empty part of the canvas, and the file paused. Open, or a double-click on the card anywhere but its name, would open the file in Card Detail. I did not need that to hear the two steps.

The spoken checklist says to lock the side door, and to leave the visitor log on the desk. I wrote those two steps in a Closing steps note in the same folder, and listed closing-checklist.m4a and closing.md as its upstream.

The same canvas after writing the steps. Lines run from closing-checklist.m4a and the Saturday closing note into a Closing steps note that lists the two actions.

This is not the same as previewing a video. Pointing at a video card plays the picture without sound. A sound card does not do that. The canvas and cards docs describe the player on a sound card.
