Hi David
Thanks for the info..grateful for any info or pointers.
I am not aware of CAED, is there a description or tut anywhere.
My aim in using Libvirt KVM is to be as bare-bones-bare-metal as
possible to lower costs.
I support a very small local station strapped for cash and staff.
Also I would be interested in net-jack if only I could get my head
around plain ol' JACK but that's for the next phase I guess.
Thanks,
Chris Perkins

Hi all,
I have been playing with a Rivendell Virtual Machine.
It's Rivendell 3.5 on Centos 7 using a Libvirt KVM Guest and a
Soundblaster Audigy card.
An NFS share on the KVM host for audio files (not yet imported) and a
reasonable Virtual HDD storage space for them once converted from FLAC
to Wav.
All is well except, the sound quality. On first listening the HDA (ICH9)
works OK but has slight distortion, which is much more noticeable when
using the test tone supplied from the build.
I know this is not a production build ( I'm still learning hence the VM)
but I wondered if anybody else has had success with this kind of setup.
I would be interested to hear.
I support a couple of Rivendell installations that use Libvirt KVM
guests. I recognize me descriptions below do not implement the use-case
you describe, but I thought I would toss it out anyway.
If you are willing to run the Rivendell service on the bare metal host,
you can use Rivendell itself (via caed) to route the audio from the
guest(s) to the host. That way you do not need to expose any audio cards
to the guest(s). This has the additional benefit that if you run
multiple guests, they can all use any of the host's configured audio
devices.
Another way to achieve the above is to use netjack. This might be a
smaller, lighter-weight solution than a full-blown Rivendell
installation on the bare metal.
Let me know if you want more details on either of these possible solutions.
And please do report back what you end up doing!
Thanks!
