Thanks for the IPCONFIG info. I'll get to that in a minute, but I just re-read the entire thread and need to think out loud here. I'm trying to understand exactly what you're trying to do that's not working. MB & SS are on the same machine. You can connect to SS via the Android phone and via a web browser. What you can't do is connect to SS from MB, correct?
To PING your computer, open a Command Prompt and type PING 192.xxx.xxx.xxx where the IP address is the address of the machine where Subsonic is installed. You'll get a response show four replies from the pinged machine. If the reply shows bytes, time, and TTL then you can successfully reach that machine. If the reply shows something like 'destination host unreachable' or 'can't find host' then your SS machine isn't reachable.
Based on your IPCONFIG data, the IP address on the machine where you ran IPCONFIG (which I assume is the machine where MB & SS live) your IP address is automatically assigned. And could change every few days. Which could be a problem when trying to reach the machine from outside.
I'm scratching my head and I keep coming back to the fact that both apps are on the same machine and you're trying to reach one via the other. And I'm thinking that may be part of (if not the entire) problem. If I get the energy, I'll do a quick install of MB on my machine which has SS on it and see if I can connect.
EDIT:
I didn't need much energy at all to install MB. I just remoted (is that a word?) into that machine, and three minutes later MB was up and running. In the Plugins preferences of MB I changed four things for Subsonic - host, port, username, and password. Obviously username and password are those which you use to log in to Subsonic. I set the port to the port SS is configured to use. I then tried two different hosts and both worked. First I used the IP address of the machine I had just installed MB on (and where Subsonic lives.) Saved the config, went to the Computer tree of MB and within seconds all my tracks were showing. Then I changed the host to localhost and again had no problem getting to the tracks via Subsonic. So they definitely can live on the same machine.
Are you certain that the setting for the port you have configured in MB is the port SS is configured for? No typo, perhaps?
I made a commitment to get this working for you and I'm about ready to start banging my head against the wall. Or change my MB skin to Sarge's WTF and stare at it until I come up with a solution.
