I play the audio output of my browsers (Firefox and Chrome/Chromium) through jack. It works with HTML5 and Flash. https://docs.fedoraproject.org/en-US/Fedora/18/html/Musicians_Guide/sect-Musicians_Guide-Integrating_PulseAudio_with_JACK.html https://wiki.archlinux.org/index.php/PulseAudio/Examples#PulseAudio_through_JACK The pulseaudio "jack" sink register as a 8 channels playback source in jack, so it works with 5.1 and 7.1 streams, not only for stereo streams. -- Marc Le Sun, 31 Aug 2014 21:42:50 +0200, Philipp Überbacher <murks@xxxxxxxxxxxxx> a écrit : > On Sat, 30 Aug 2014 07:38:33 -0300 > Iain Mott <mott@xxxxxxxxxxxxxxx> wrote: > > > > > Hi list, > > > > I'm thinking of updating some of my web pages to use multi-platform > > flash/html5 audio players, at present they use flash only and won't > > play on iPads for example. > > > > Due to some problems I was having with pulse audio in relation to my > > HDSP interface I have recently disabled it and all my audio is > > running via jack/alsa and the HDSP interface.
