Feature request: no mute-button; no volume slider

I am designing a web page for audiobooks to be listen also for visulally impaired. This audioplayer template 1, (as the WP native player as the prototype) can be easily handed with keyboard. I like the template 1 of Compact WP more as I can minimize the empty room between text and player, and it keeps that unlike with the WP native player. In both players (WP native and Compact WP templ-1 when moving cursor onto volume slider by Tab key it goes only quieter, but not louder (to right) with keyboard (left/right arrrow). The Mute-button turns also volume with up/down arrow keys, but I would like to remove it because of risk accidentally muting audio. It would be nice also to have a choice to remove the volume slider at all. In both cases it means that there were also absent the placekeepers of these buttons (the cursor would go straightly from time slider to next player).
With best regards and thanks,
