Why www/chromium port default AUDIO option set to PULSEAUDIO ?
As far as I saw in log, default AUDIO changed from ALSA to
SNDIO in Fri Oct 23 20:48:38 2020 :

commit 288df69b89b14cea63c11bc2b0fd541749ffa0b2
Author: Joseph Mingrone <jrm_at_FreeBSD.org>
Date:   Fri Oct 23 20:48:38 2020 +0000

    www/chromium: Use SNDIO instead of ALSA for audio by default
    
    There are stuttering sound issues when using ALSA, so switch to something
    that works.
