However, when I read that the new Pulseaudio 11 includes these changes and that it should now work, I got really excited. </div><div><br></div><div>However, I'm having the exact same problem that I did before. I enable Airplay discovery in PA-prefs, and GNOME Sound Settings detects my Airport Express (it's listed twice for some reason). However, when I select one of them and use the Test Speakers function, no audio can be heard. All volume sliders are on full.</div><div><br></div><div>Playing a track using Audacious for example, whilst Airport Express is selected for output, results in no activity at all, the track doesn't even begin to play, with the track time stuck at 0:00:00. Switching back to Built-in Audio works fine.</div><div><br></div><div>I'm using a fully updated Arch Linux and Pulseaudio 11.1. I have no password set on my Airport Express and it works fine using iTunes on my </div><div>Mac (which I make sure is disconnected before trying it on my Linux PC). </div><div><br></div><div>With Tanu's help, I managed to get some log output from PulseAudio to see what was going on.</div><div><br></div><div>In terminal 1: </div><div><br></div><pre> pulseaudio -vv </pre><div><br></div><div>-
