There are no tooltips available for the Wind Forwards and Volume controllers of the Media Playback toolbar. Steps to Reproduce: 1. Open IMPRESS 2. Go to INSERT -> MOVIE AND SOUND and insert a sound or video file 3. (Optional if you had never activated the Media Playback in the past) Go to VIEW -> TOOLBARS -> Select the MEDIA PLAYBACK toolbar 4. Click on the media file 5. Move the mouse cursor over the Wind Forwards and Volume controllers of the Media Playback toolbar Result: There are no tooltips available. Reproducible with LO 4.3.4.1 and 4.4.0.0.beta1 (Win 8.1).
Confirmed on Linux. Version: 4.5.0.0.alpha0+ Build ID: e570cd7a293ceee175949dcc9656cdf776ae3c37 TinderBox: Linux-rpm_deb-x86@45-TDF, Branch:master, Time: 2014-12-12_18:49:54
For me the same on Windows 10 Pro with LO 5.2.4.2 32 bit.
So the entire playback control is stored in the .uno:AVMediaToolBox UNO command which means that this will require dev work to fix. Not as crucial as it used to be as the media playback content panel is now in the sidebar and the toolbar is off by default.
