Remote Control from Android App to Linux Server

[wamakaska]

Problem Description: I am attempting to use the remote control feature in the Android app to play music through the server. As far as I can tell the server is not playing the audio at all.
Troubleshooting Steps: I tested the audio on the server and it is working fine for all other applications
Playback Application and version: Android app, most recent update available
Subsonic Version: 4.7 (build 3105) – September 11, 2012
Server Version: jetty-6.1.x, java 1.6.0_27, Linux (43.8 MB / 85.6 MB)
Hardware Platform: Ubuntu 12.04 LTS , Running inside VirtualBox 4.2.6 on Windows 7, shared audio, tested and working with MOC (music on console)
Java Memory Limit: unknown (Prob default for linux ver, haven't changed any settings.)
Problem Filename: IR
Output from ffmpeg -i: IR
Last ten log file lines: IR

EDIT: Found the solution in this wiki page under the heading 'Selecting the Soundcard'

Kinda bumping this cause I have the same problem. It's funny, cause it works sometimes, and I can't seem to figure out what is changing.

I've tried using the Android app, and DSub. I've had this problem running Ubuntu 12.04 and Linux Mint. If it helps, here's something suspicious looking from my subsonic.log
