That's why it has obsolete software that is no longer supported except by Red Hat engineers. And since you are not a paying customer of Red Hat, they won't support you either. And here is a reasoning behind Enterprise distributions: they never break anything for years (which is important on servers and in big corporations), but the price is that they also never fix anything except security issues and never update non-leaf software packages even between the point versions, because this might break some in-house thing, which is, again, a no-no in big corporations. So you are not just behind by 0.1, but will always be stuck in 2010 as long as you stick with CentOS 6.x releases. Unfortunately, it is impossible to upgrade PulseAudio in CentOS, even by building from source, because (due to shared library incompatibility) this WILL break all existing applications there. If an enterprise distribution works for you, great, it will continue working for 10 years on the same hardware even if you upgrade to next point releases. If it doesn't (which is exactly your case) - deal with it, it is essentially unfixable. Or invent workarounds. In your case, such workaround may be to use a DVI-to-HDMI cable, because nowadays there are no true DVI ports, they are almost all HDMI in disguise, and maybe that's what is DEV=0 on your computer. Once again, enterprise distributions are not recommended for home users. Next time, please install any of the following: Mint, OpenSUSE, Arch, Fedora, Ubuntu (including variants like Xubuntu), Gentoo, or Debian Testing (not Stable, because this is essentially an enterprise distribution, and they themselves recommend Testing for home desktop users). > Do you think the fact that I can't run pavucontrol as a regular user has > anything > to do with it?
