How to configure Jriver 19 to Airport Express

I use to work with Itunes and was streaming audio to another room using Apple's Airport Express. Everything worked fine. I started to use Jriver 19 about 6 months ago and now want to use the Airport Express device to stream music in my living room. I have read a ton of threads on the Internet and looked at JRiver help section, which is really useless on that subject.

I have read that I needed to install the DBpoweramp Asset UPnP audio server which should be compatible with JRiver. I have created a living room zone and a Airport Express zone in JRiver which I can both see in the 'Playing Now' menu section. I have downloaded the main Library into the living room zone and no audio playing, what could be the problem?
Airplay is supported as an audio device in Mac OS X. So you can set the Airport as the default Core Audio Sound Device and set JRiver's Audio output to go through Core Audio.

But I gather you are using a PC?
Yes and operating under Windows 7 OS.

Thanks anyhow.
Why not Itunes?
Because it does not support DSD downloads. I have purchased a Benchmark DAC2 HGC to be able to listen to DSD downloads. Little disappointments about poor availability of music DSDs in general.
Dasign, but how do you connect DAC2 for DSD. If it is by USB cable can you use it in asynchronous mode for PCM?
JRiver allows you to configure itself to scan for music library changes for auto import.

One workaround on the PC is to use iTunes to maintain your main music library. So you can still use it to send music via Airplay to your Airport Express (not DSD tho).

JRiver can read from the same library (plus another folder for your DSD stuff) when you want to play DSD.

On the Mac, I use Audirvana/PureMusic to add DSD playback to my iTunes.
Thanks Doggiehowser,

I have tought about doing so as a 'B' plan. However, there are some folks that have been able to configure Jriver to operate with Apple's Airport Express. I would like to avoid using 2 music player applications. I just need the recipe from those who were facing the same issue using Jriver 19.
You may have to purchase AirFoil which does what OS X's audio controls do - maps the Airport Express (and Airplay devices in the network) to an Audio Device in Windows Control Panel - Devices/Sound.

That way JRiver will just see it as another audio device to play to.
Thanks Doggiehowser. I have read users successfully using Airfoil with Jriver. Will give it a try in a few days.
I had this delimma as well. I did try airfoil but it ultimately was not a stable solution. I later did some serious evaluations of jriver vs itunes for sound quality and discovered they sounded virtually identical, so I ditched jriver altogether.
