            Bug ID: 1092136
           Summary: Docker commands pause streaming audio
           Product: Fedora
           Version: 20
         Component: docker-io
          Assignee: lsm5(a)redhat.com
          Reporter: mdavis(a)redhat.com
        QA Contact: extras-qa(a)fedoraproject.org
                CC: admiller(a)redhat.com, golang(a)lists.fedoraproject.org,
                    lsm5(a)redhat.com, mattdm(a)redhat.com,
                    mgoldman(a)redhat.com, s(a)shk.io, vbatts(a)redhat.com



Description of problem:

Execution of docker commands cause streaming audio to pause briefly (3-4
seconds)


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

[root@dhcp81-173 ~]# rpm -q docker-io firefox flash-plugin
docker-io-0.9.1-1.fc20.x86_64
firefox-28.0-3.fc20.x86_64
flash-plugin-11.2.202.350-release.x86_64

[root@dhcp81-173 ~]# uname -s -r -v -m
Linux 3.13.10-200.fc20.x86_64 #1 SMP Mon Apr 14 20:34:16 UTC 2014 x86_64



How reproducible:
Nearly every docker command does this.

Steps to Reproduce:
1. Start up firefox and start listening to a streaming audio service (I
reproduced it on spotify.com, using the spotify web player)
2. Run a docker command. For example...

[root@dhcp81-173 ~]# docker images
