If one wants to avoid pulseaudio and stick with just alsa, one needs to run for example "/usr/bin/apulse /opt/bin/skypeforlinux" but likewise, for firefox/seamonkey if one wants to have a working sound+microphone in a web browser (youtube, facebook, google hangouts). USE="-pulseaudio alsa" The "Applications" menu entries cannot be easily edited by right-clicking. Could Gentoo fix the executable links by prepending /usr/bin/apulse in front of the real apps? I assume these should be fixed: Seamonkey Aurora/Firefox Skype probably others. This is not just an xfce4 issue I believe but it is the window manager I use at the moment. I care about this because time to time I tend to forget this trick and I fight with skype/hangouts giving me no sound+mic. I have media-sound/apulse-0.1.10 at the moment. # emerge --info Portage 2.3.22 (python 2.7.14-final-0, default/linux/amd64/17.0, gcc-6.4.0, glibc-2.25-r10, 4.15.4 x86_64)

Gentoo won't be patching every ebuild to support hacks. If you want hacks, you're on your own.
> The "Applications" menu entries cannot be easily edited by right-clicking. You can use x11-misc/menulibre and/or copy desktop files from /usr/share/applications to ~/.local/share/applications and/or edit them, possibly using an intermediate bash script. That's what I do to customize the way google-chrome and qpdfview start.
