On your "stream" question, I'm not sure if you are trying to connect
Rivendell to a live stream, or simply be able to remote record a stream
into a file for later playback.
For the live steam case, yes we do that all the time. The key is to get
Jack running then use a player of your choice to play the stream, as
long as it supports jack. I have used both mplayer and VLC, but mplayer
is easier because you can get it to have a consistent jack name where
VLC always gives you one with it's process ID attached to it (always
different) so I have to use an external shell script to sort it out.
For the non-live setup, I've never done it quite this way before, but do
a similar thing but configure the "player" to write to a file instead.
Then you can either use the "dropbox" function built into Rivendell to
automatically import it or call "rdimport" manually to do it. Either
way should do the job. You can use a Rivendell macro to automate all
this as needed.
On your overall audio problems, yes we in the community can help to
some degree but will need more information about what distro you are
using, what sound hardware, and what some of your configuration files
look like.
Yes Fred at Paravel does offer paid-for support, but last time I talked
to him he only wants to support his appliance distro (and his turn-key
systems). I support his decision on this as there are major differences
in Linux distributions out there and I feel it would be too much of a
distraction for Fred to attempt to offer support on all of them. I'd
rather like to keep him focused on improving the Rivendell software
itself. So unless you are using something running his appliance, you
need to rely on either us or your own experimentation to get things running.
That said, I do find Rivendell a lot trickier than I'd like to see to
get set up and I'd recommend taking notes along the way of what ends of
working on the systems you are building so you don't have to figure it
all out again later. I think I would try getting things working in ALSA
(or HPI if you have a card) first, then converting it over to Jack later
as Jack also can be tricky to setup.
Sorry I don't have any specific answers to your questions here, but I'll
need more specifics from you, like does your system have Pulse Audio
layer running? Can you play anything out of your sound device from any
other program? What does your /etc/asound.conf (and/or ~/.asound.conf)
look like? When you fool around with "alsamixer" (or any other ALSA
mixer control you have), and review all the ALSA devices it has
registered (For example, I have a "loopback", an Integrated Intel sound
device, and a USB audio device on my system, but mine is more
complicated than many), can you double check that nothing is turned down
or muted? Note that the labels on the controls in an ALSA mixer is
sometimes WRONG! so you need to manually verify that each control really
controls what it says it does. If you have Pulse running, it often jump
in front of all the underlying ALSA controls and make them hard to get
to (but still possible).
Expect to learn more about ALSA (as well as Pulse and Jack) than you
ever thought existed before this is over. I learned some really cool
things you can do with ALSA from my experience getting Rivendell working
the way I wanted on our system, and Jack is simply awesome.

Thank you Lorne! I have to admit, I'm still very new at using Rivendell, but my
years of Linux administration have smoothed out some of the bumps, and your
guide explained the process very well.
Now the next hurdle is getting Rivendell to work at all. I've yet to play out
any audio, despite trying a myriad of configurations and base OSes. You
mentioned that I'm using JACK, which will be true, but even without it... I'm
still encountering issues.
I just wish I could pay someone to help me sort this out! Hopefully I'll figure
it out soon.
Nicholas
