Excuse the long post. 

 

I qualify this post with the comments that while I am not a total Linux 
beginner I am

also not intermediate nor advanced in my knowledge of Linux.

 

I have no real experience of installing and running VM stuff.

I’m currently using Rivendell 2.10.3 to play on-air programming for my LPFM

 

It runs under Ubuntu 12.04 and works well but is dated and I am thinking of

updating to the latest  version of Rivendell using the available CentOS 7 
turnkey

image and doing whatever the steps are needed to move my music and database 

over to the new 3.x build

 

I'm pondering trying to move to this, but there's more :)

 

The current Ubuntu box has a PCI mobo with a legacy M-Audio Delta 44 in it. 

I want to keep using this card if I shift to the new OS.

I’m told the card should work under Rivendell 3.x the trick is to find ‘new’ 
older

hardware that has a PCI card in it. I don't disagree. I can't really update the 
on-air

box without major impact so starting over with a new box build is the better 
way to go.

 

The current Ubuntu box has this legacy card plumbed into it. The card has x 2

stereo in and outs. The two stereo outs play into a mixer, the mixer

stereo out is fed into a different (identical delta 44) soundcard that sits on 
a Win

XP box.

 

This XP box has legcay win32 bit software that takes the input of the card

and encodes it to be sent via UDP to another PC running the same win32

software. It decodes the audio, processes it and feeds it to the TX.

The only reason I have this XP box running at the studio end is to take the

audio ex mixing desk, encode it with legacy Win32 software and then 

fed to the TX site.

 

Ideally I'd like to remove the physical XP box to cut down on PCs running and

chewing up power.

 

Instead I'd change the audio chain to do the following (if I can…)

 

Radio Playout box

 

- running CentOS 7 and Rivendell 3.x  and outputting radio music via current 

Delta 44 soundcard into mixing desk.

 

- output of mixing desk back into one stereo inputs on same Delta 44 used for

Playout to the mixing desk

- Have a XP VM set up and running on the same CentOS 7 box as Rivendell

 

- employ some Linux virtual audio cable software that creates an audio link to

the XP VM. Guessing something like VAC or I hear of Jack mentioned etc?

But unsure what and how to set this up.

 

- the XP VM win32 bit software would see this sound card virtual audio cable

from the CentOS 'parent' as a valid input to listen to.

 

- The win 32 bit software within the VM runs as per usual and encodes and

sends audio to another PC via UDP

 

What I am wondering is ... well a bunch of things

 

Can I run a VM running Win XP on a CentOS box?

 

What hardware specs will I need to allow for the VM to do this?

 

What hardware specs will I need to allow for the CentOS box to allow to run

the radio playout software without issue?

 

Importantly - is there virtual cable software out there that I can use to take

sound from a soundcard in Rivendell / CentOS 7 and feed it as an input to win32 
bit software

running on a VM in the same physical machine that will see the audio as valid 
input on a soundcard?

 

Is anyone has any experience running Win32 audio software within Linux and/or

CentOS specifically I'd be interested to chat with them :)

 

I need to stop drinking caffeinated drinks early evening :)

 

Thanks for reading and any feedback you can offer.

 

Best, Paul.
