Sorry about the top post. I'll try bottom posting in this post and see if it 
works.
I haven't used a mailing list for a while and I forgot about making sure to 
bottom post.
I just tried removing pulseaudio and it didn't help.
I then tried rebooting and it worked. I don't know why I didn't think of it 
before.
I'm just reinstalled pulseaudio as I'm using the network audio feature.
It appears pulseaudo does work with mythtv.
Something just needed to be restarted after an update.
