Under ALSAMIXER there is no hdmi device, yet the sound, without vu control comes out the monitor headphone socket.<br>
With another monitor, ASUS, there IS a hdmi sound device and the level can be changed<br>
<br>
The USB sound dongle was $10 so I’ll mutter the rude word, beeep, and keep using it, where all is works as expected<br>
<br>
Thanks<br>
