[Nix-dev] Chromium not working with pulseaudio

[Jessica Taylor]

Hello.  I recently installed NixOS and found that most things worked, but
I'm having a problem with audio.

When Chromium should play a sound (such as with HTML5 video or Gmail), no
sound plays, and Chromium is not listed as an application in pavucontrol.

I have pulseaudio enabled:

> hardware.pulseaudio.enable = true;

Firefox can play sounds just fine (and appears in pavucontrol), so it
appears to be a Chromium-specific issue.

I have Chromium explicitly configured to be compiled with pulseaudio
support (which I think is already the default):

> nixpkgs.config = {
>   ...
>   chromium = {
>     enablePepperFlash = true;
>     enablePepperPDF = true;
>     pulseaudio = true;
>   };
> };

I tried following the directions in
http://article.gmane.org/gmane.linux.distributions.nixos/12117/match=chromium,
but this didn't help.

Thanks,
Jessica Taylor
