The trick is using dmix on loopback device:
2 dmixers; one for regualr onboard audio; the other for loopback virtual device, then duplicates streams send to onboard audio card, so you can hear what is being sent to loopback device.

Need to load snd_aloop module first;

Code:
modprobe snd-aloop index=2 id=Loopback pcm_substreams=1 enable=1
My first audio device is onboard soundcard; 2nd is HDMI card, so I put index=2 for Loopback device.

[solved] HTML5 Youtube with no video on Firefox/Iceweasel, in Debian testing/Stretch

Googling a little bit about, some solutions to the same symptoms pointed to needing to install something like gstreamer-ffmpeg. But not only that's unavailable in the latest Debian testing (Stretch), but it seems it's the other way around: for me it started to work again when I deactivated something related to gstreamer on about:config.

Doing so doesn't seem to have affected anything else (namely flash videos). But I feel that now HTML5 on youtube is somewhat heavier, buy maybe it...
