REPRO
- Make sure your sound playback equipment is correctly setup.
- Enable Edit menu > Preferences > "Play Streaming Music When Available".
- Go to a parcel with a music URL playing. (About Land > Media tab's "Music URL".)
- On Music control above the toolbar, move the volume slider to maximum (all the way to the right).
- Push play button.
* Observe: Volume level is loud.
- Relog at same location.
- Push play button again.
* Observe: Volume is much softer, even though you didn't change the position of the slider.
= Expected: Volume level should correspond to slider position.
> Workaround: Click the volume slider to reset the volume level to its actual setting.

I was able to repro this on Windows. I wasn't able to repro it in the First Look: Voice viewer with rearranged sound controls.


Original info from Barney Boomslang:

When setting the slider for the stream sound volume, that slider position is saved. But on login, the actual stream volume is very low. If you touch the slider itself only once - no need to actually slide it, just press it - the sound reverts to the actual setting in the music control and works fine until the next login. Looks like the stream volume is reset to some internal default on client startup.
