Tabs can be (un)muted, etc. However no alsa or pulseaudio sound stream is available in pavucontrol. This issue has also been reported on irc (#gentoo-qt) to affect: =kde-apps/konqueror-16.12.0:5::gentoo including a pure alsa sound setup...
Created attachment 457148 [details, diff] qtwebengine-5.7.1_alsa-fix.patch This hacky patch (by Chiitoo) appears to fix the html5 audio issues for both Konqueror and Qupzilla (qtwebengine -based). It's been tested on Gentoo installs with both pure-ALSA and Pulseaudio sound systems. On a Pulseaudio Gentoo setup - the Qupzilla sound stream came through "perfectly"(TM) as an Alsa-plugin[Qupzilla] audio stream (volume control, etc. all work). The patch is very useful to have (IMHO) - till a more "refined" solution arrives!

I'm having the same exact issue, with both QupZilla and Qutebrowser (Git version, only with webengine backend) I'm adding my emerge --info and qtwebengine build log in the hope to help
Created attachment 458190 [details] Emerge --info
Created attachment 458192 [details] Latest QtWebEngine build log
I can confirm that the proposed workaround works both in QupZilla and QuteBrowser with the WebEngine backend enabled
This patch solves this issue for me too, thanks!
Solves it for me also : thanks !
This has been fixed in git. https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e146460dfde8972861dae5099f45e9dee5da2b6b
