[Bug 294666] Re: PulseAudio causes sound latency in 8.10
I've been trying to use the fix from comment #34 in 11.10 (Unity), this far without success. I copied firefox.desktop from /usr/share/applications to ~/.local/share/spplications and modified it there so that it executes /usr/local/bin/firefox For the rest I followed the steps from comment #34. However, when I click the Firefox button in the Launcher (or whatever that taskbar is called in Unity), nothing happens. When I run the command 'firefox' in a terminal, I see why: I get the message 'permission denied'. When I run 'sudo firefox' all seems to go well, but I'm not too comfortable running the browser with administrator privileges. What is the best way to apply this workaround in Unity? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/294666 Title: PulseAudio causes sound latency in 8.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/294666/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Is there some sort of configuration file I can add that export command to, so Firefox always starts with that setting?

[Bug 294666] Re: PulseAudio causes sound latency in 8.10
What you can do is create a script that sets the variable, then launches Firefox. Just run 'sudo gedit /usr/local/bin/firefox'. Then paste the following into the file and save: #!/bin/bash export PULSE_LATENCY_MSEC=20 exec /usr/bin/firefox $@ Then run 'sudo chmod a+x /usr/local/bin/firefox'.

Ahh ok, I thought that variable would be applied system-wide, so I started Firefox from the top panel.

@Jordy The value that best works for each configuration really depends on the audio hardware, so it's very specific to a class of controllers/codecs.
