Hosted PCM: Rework auto-muting code a bit

Browse source 
* If AUDIOHW_MUTE_ON_PAUSE, no meaningful change
     * Unconditionally unmute on playback start
     * xduoox3ii:  Mute on sample rate change
     * rocker/xduoo:  Stay muted after startup

    This avoids the nasty "pop" on startup, without doing
    the full mute-on-pause stuff that causes unacceptable
    dropouts on the X3ii.
