Bug 22541

Description of problem:
I have a constantly running sound feed on my LAN which connects to any of several machines which each run PA servers.

Each time I close the lid of my laptop it suspends.

When I re-open the laptop a new TCP connection is created and the sound is played again.

All works fine, except that on each suspend/resume a fresh volume slider is created for the newly opened stream in addition to the original(s).

Today I ended up with 14 volume sliders!

Should there be some mechanism to check whether TCP connections are still alive and close any dead ones?

Version-Release number of selected component (if applicable):

Happens in pulseaudio 10.x and 11.1 in plasma5 on Mga6 and Cauldron

This is a duplicate of my bug already reported upstream in order to track this:

How reproducible:
Always

Steps to Reproduce:

1. Run e.g. rtl_airband using pulse option on a machine.
2. Set up another plasma5 machine running PA server configured to listen for TCP connections on the LAN.
3. Play stream, suspend machine, wait a few mins and resume. Note an extra volume slider in the plasma5 'audio volume'. Repeat to collect more sliders.
