Please don't top-post.
I think you have pointed to your problem. Pulseaudio is definitely not
yet ready for prime time. It was installed by default on my Fedora 8
setup and I had to remove it as I could not get audio to work.
And obviously, the box is capable of doing what you want.
I suggest you try an 'apt-get remove pulse*' or whatever. Otherwise, if
it wasn't your laptop, but a dedicated system, I would suggest a mythtv
database backup and re-install. But I strongly suspect that your laptop
has a large number of other programs on it.
No easy answers to this. as ISTR that removing pulse was a pain,
although I cannot remember the details of what I did (and it likely
would be of no help to you anyway due to the different distro).
