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

[root@dhcp81-173 ~]# docker run 0d2 id
uid=0(root) gid=0(root) groups=0(root)
[root@dhcp81-173 ~]#
Actual results:
Currently playing audio paused for 3 seconds after running the 'id' command.
Expected results:
Uninterrupted audio playing
Additional info:
I'm running Fedora 20 XFCE build.

Are you still seeing this with the latest docker program?

Unfortunatly, I am.
It takes ~4-5 seconds for the delay to kick in, then it is paused for ~2.

I wonder what could cause this? Does your CPU go nuts when starting the docker
container?
Might be a kernel issue.

Does it happen with all docker base images?
Does it happen in another desktop environment?

Does it happen with all docker base images?
Yes.
Does it happen in another desktop environment?
Have not tested,
I will try to test this later.
Also to note, this is also impacted by virtual machines. If I start a VM or
stop a VM, I experience the same 'pause' in audio.

Then that would seem to be kernel related.
