I have this setup: laptop with wifi-AC -> AC capable router -> laptop with AC (directional antenna) -> hi-fi speakers.

I don't have any network problems, everything is really fast and I can play(stream) 1080p video from one laptop to another with smb (Samba & vlc).

The problem is that when I only want to stream the sound output from one laptop with Pulseaudio, I get constant and annoying glitches. It is worse when I'm playing a Youtube video.

I have Ubuntu 14.10 on both laptops. I have played with pulseaudio settings with no success.

Do you have any idea what can I try in order to have a smooth playback over network? Maybe some pulseaudio settings or another solution...

Thanks

You can stream audio and video with vlc :
f.i. this is a command to stream a video file from your local disk Video/video.mp4 to a multicast destination on your lan (copy the command as a single line in a terminal, replacing filename)
vlc --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=2000,ab=128,deinterlace}:rtp{mux=ts,dst=239.255.12.42,sdp=sap,name="TestStream"}' Videos/video.mp4

On the reading pc(s), run vlc and open the stream rtp://239.255.12.42

You can change source file Video/video.mp4 by a youtube url like https://www.youtube.com/watch?v=afBm0Dpfj_k

EDIT: to stream audio only as played on your first pc, just change source file Video/video.mp4 with pulse://
vlc --sout '#transcode{vcodec=mp4v,acodec=mpga,vb=2000,ab=128,deinterlace}:rtp{mux=ts,dst=239.255.12.42,sdp=sap,name="TestStream"}' pulse://

Look here for streaming using vlc interface instead command line.
Look here for more command line streaming (set stream video size , format etc...)
You can also remotely control the streaming vlc from a web interface on the reading pc: look here

  • This would work but it is not as easy as just streaming everything that goes to the sound output. e.g: Now I'm listening to an mp3 and, in the next moment, I want to stop mp3 playback and listen to something on YouTube or another site. – Radu Gancea Oct 31 '14 at 11:43
  • Edited the answer: if I understand well, you want to stream audio only for listening on your hifi speaker – laugeo Oct 31 '14 at 17:59
