OPi 3 sound problem in Firefox (vlc plays mp3 OK)

[laurentppol]

Hi there,

with Armbian Buster "OOB" (+update) I have following problem on Orange Pi 3:

- Firefox (with language Polish) does not play network radio: https://www.rmfon.pl/play,25#p ,

- at the same time:

   - there are /dev/snd/ files, only for HDMI, but I have read that currently there is no driver for H6 audio, so I may expect at least ALSA is working,

   - VLC plays MP3 files correctly, (but it can play with pulse and ALSA),

   - pulseaudio is not started / configured / present.

 

What should I do?
