Pulseaudio doesn't work

[equal-l2]

• Ran brew update and retried your prior step?
• Ran brew doctor, fixed as many issues as possible and retried your prior step?
• Confirmed this is problem with specific formulae and not Homebrew/brew? If it's a general Homebrew/brew problem please file this issue at https://github.com/Homebrew/brew/issues/new

Pulseaudio doesn't work at all.

brew doctor

Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

Warning: Unbrewed header files were found in /usr/local/include.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

I had this problem too. It seems to be a problem with dbus (permissions perhaps..?).

A workaround is to install pulseaudio without support for dbus.

brew install --without-dbus pulseaudio

[ilovezfs]

My fault. I listened to configure's warning that it should depend on dbus if possible. This will be fixed by #9473.
