Here's what I have - looks right to me.

# ls -l /dev/audioctl /dev/audio /dev/sound
lrwxrwxr-x  1 root  wheel  11 Apr  4 16:06 /dev/audio -> /dev/audio2
lrwxrwxr-x  1 root  wheel  14 Apr  4 16:06 /dev/audioctl -> /dev/audioctl2
lrwxrwxr-x  1 root  wheel  11 Apr  4 16:06 /dev/sound -> /dev/sound2


Maybe I need some special build options for pkgsrc?  Here's an
excerpt frm my build loggs:

==========================================================================
The supported build options for firefox are:

        alsa dbus debug debug-info jack mozilla-jemalloc
        official-mozilla-branding pulseaudio speechd
        sunaudio webrtc

The currently selected options are:

        alsa dbus pulseaudio sunaudio webrtc

......

==========================================================================
The supported build options for chromium are:

        alsa debug pulseaudio sunaudio

The currently selected options are:

        alsa


I also notice that both browsers appear to attempt to open /dev/video
resulting in lots of

	WARNING: module error: module_load_vfs_vec() failed for `video', error 2

on the console.
