GIA-3276 - With new disabled input fields for Audio player counter to stop users being able to edit the counter times and to prevent the device virtual keyboard from appearing, the colour opacity is reduced to 0.2 to indicate the fields are disabled as a default webkit behaviour. Therefore I added opacity of 1 to the .audio-player__slider__played, .audio-player__slider__remaining  classes to prevent this from happening, so the appearance is the same as before and same as on Android.
