Look, for starters your original post is still confusing to me --- you seem to be computer savvy, and maybe as Hiltonk very politely suggested, lets simplify this , cause this is going in circles here.
My headless audio PC is connected to DAC. It runs JRiver Media server only. I want to run JRiver on my desktop PC with no speaker (all files are here) and listen music through that audio PC via intranet. Isn't it possible?
First, I read all the files are here (like a PC with no speakers has your files in it) then I start to think you have a NAS. Then I think there was some confusion that you want to stream by "internet" (possible btw), but you said "intranet" (like local network). I'm sure most people use jriver on multiple computers, so its very hard to "replicate" your problem.
SO -- I'm not sure if you have a NAS or not but lets get some semantics out of the way, and when I get off work (another 5 hours GMT+1) I think I can help you if I understand your system. Let's use this as an example (forget Audio PC headless etc.). I also think you are getting confused with libraries and zones maybe but not sure ...
Lets say, just for the moment that you have 2 PCs running just Win7 -- one has the files on it. One does not.
Normally, the one you have the files on PC1= SERVER, PC2=client.
The server must be accessible (on or can be "woken up"), for the client to control or playback the media. You can TAG and organize your "principal" library (server PC library) from the CLIENT, but you must import from the SERVER. You can control playback from each, but the configs are not (all) Zone specific. If you want to go headless (which I interpret to mean no monitor) It is highly recommended to temporarily attach a monitor or at least a TV for its initial setup. With two PCs like this example below you want to share libraries not use just DLNA.
The reason I say "principal" library is that each PC running jriver will have its "main" library which is really a local library. The CLIENT must load a remote library from the SERVER in this case
Now before going on, have to get back to work, reading the thread, I'm assuming the following:
- that you have checked eventual problems with firewall and AV software
- that you have checked that your router is also not blocking anything and the PC SERVER allows the port 52199 specifically
- that you can temporarily attach a monitor to your "headless" (I have a solution if you can't buts its a pain
- your headless HTPC is an actual PC and not a streaming box like Sonos or a Linn or Naim "device"
So questions/clarifications if you don't mind please - just to be sure
are your filenames including paths longer the 254 characters?
what machine will actually hold your media files (right now I'm assuming its your desktop PC or is it a NAS? (really confused about that one sorry)
can you check what Media Type these files have been tagged (eg Movie, Audio, etc) and what file extentions are you using?
I feel for your frustration, sometimes post get lost in the sauce so to speak which would explain the lapse between your June post .... but looks like people have been responding repeatedly since then (including the CEO for Pete's sake) so keep your pants on and you'll be up and running soon.
BTW the unreachable gentlemen you refer to are here to help, and aren't paid to do so - if you haven't already read this, please do
