Whenever heavy traffic starts on my network, Rhythmbox will abruptly stop playing audio streams. The traffic in question may be local data transfer or (mostly large) downloads.
The same happens to local audio streams managed by pulseaudio. A data transfer starts and the stream very much immediately cuts out.
Typically, rhythmbox will pops up a dialog saying "server does not support seeking". I can usually resume playback but during longer data transfers/downloads, it will frequently cut out again.
I have tried replacing the onboard audio chip with a discrete ASUS DX card. This does not make any difference.
What does work is manually restricting download speeds using a download manager. However,, not all network traffic is controlled by such a manager. Something trivial - say, installing a firefox or a gnome-shell plug-in - has been enough for an audio stream to die instantly.

What is your network speed ( mbps ) ? When you start your downloads, does other apps ( browser page loading / youtube in browser ) work fine or they are stalled too ?
You can give the following steps to get some insight into the issue:
1. Rhythmbox ( RB ) uses gstreamer backend for playing audio files. This step confirms if the problem is with gstreamer or RB. Run the following commands from the terminal.
$ sudo apt-get install gstreamer1.0-tools
$ gst-launch-1.0 playbin uri="http://
This should play the audio stream. You can substitute your audio stream URI in the above command. Now start the downloads. If the playback is stuck / aborted etc, the same way as it happens in Rhythmbox, this is a gstreamer limitation and RB can do very little about it. Try opening a gstreamer bug at https:/
2. If audio plays fine in above step, start rhythmbox in terminal as below
$ rhythmbox -d &> ~/rhythmbox.log
Start audio streams followed by downloads. Wait for the playback issues to show up. Quit Rhythmbox and attach rhythmbox.log in this bug report.
