f20 - audio problem

[Mike Wright]

Hi all,

Exploring f20 and have a self inflicted wound.

While trying to get flash to play on vlc I found a conflict between 
libvpx and some other libraries so the resident genius yum removed it, 
and all of the other packages dependent upon it, thinking they'd be easy 
to reinstall.

Not the best idea.  Now I've got all sorts of video but not a peep of audio.

I yum installed alsa* and pulseaudio*.  The ALSA mixer I have now looks 
nothing like the one here before.  Pulseaudio volume control->Playback 
says "ALSA plug-in [plugin-container (deleted)]: ALSA Playback"  but yum 
list reports alsa-plugins-pulseaudio-x86_64 as an installed package.

I couldn't find an Audio Group.  Does anybody know how to reinstall the 
standard f20 audio packages or where I can find a list of packages 
installed into a fresh f20 system (from the live xfce spin)?

Thanks,
Mike Wright
