[solved] Tracks simply won't play. All else seems normal.

[rumremix]

Problem Description: Tracks will simply not play. For example, if I try to play a song from the play queue in the standard browser player, a tiny segment will appear at the left end of the song progress bar for a moment (as if the song is starting), and then vanish. The play button will change to a pause button for a microsecond and then change back to a play button. The time elapsed will never advance past 00:00. Even worse, I hear no music.
Troubleshooting Steps: I tried restarting the subsonic service, restarting my computer where the subsonic service lives, re-installing subsonic, looking for log errors, testing from various apps and browsers (see next section for more on this).
Playback Application and version: Chrome browser, firefox browser (using standard server-address/index.view player), sonos, AVSub, iSub, JamStash. I won't list version numbers unless someone thinks they are necessary (I assume not since the issue spans many applications).
Subsonic Version: 5.2.1 (build 4428) – March 4, 2015
Server Version: jetty-6.1.x, java 1.8.0_45, Windows 8 (81.9 MB / 145.0 MB)
Hardware Platform: Windows 8 PC
Java Memory Limit: Ran into something interesting when I went to look for this. Saw a "Memory Used" field (60MB) but no "Java Memory Limit" field. So I assumed that field must be available from the other ("Settings") tab. However, I am unable to switch to the other tab by clicking it. The subsonic control panel seems to be having some rendering issues. If I click the settings tab, the view doesn't change. But if I click around, some elements from the settings tab become superimposed over elements of the Status view. A jumble. Seems unrelated to my issue but who knows? In any case, the field titles are not visible so I can't determine the java memory limit.
Problem Filename: None that I am aware of.
Output from ffmpeg -i: Not familiar with this. Perhaps not relevant since I'm not aware of a specific problem file? So not sure what I would type into command prompt for file portion.
Last ten log file lines: Last ten lines are all "MediaScannerService Scanned media library with x# entries". And attempting and failing to play a track adds nothing new to the log even after I refresh it.

I really appreciate any suggestions. Subsonic is now the primary way I listen to music everywhere. Thanks!

UPDATE on Java Memory Limit: After reinstalling subsonic, the subsonic control panel rendering issues seem to be resolved. Under the "Settings" tab, the "Memory Limit" field shows 150.

I still cannot play songs, however. Appreciate any help.

Trying not to panic here. But I am a music addict and subsonic is my primary source at work, in my car, and at home -- now that subsonic works with sonos . My subsonic service will no longer stream to any device or app (I can now add JamStash to the list).

No one has any troubleshooting suggestions at all? Ok, then I'll ask this: should downloading and re-installing the latest subsonic bits (which I already tried) have the same effect as first uninstalling subsonic completely and then re-installing? Aside from that I cannot think of anything else to try.

Really appreciate any advice at all.

Awfully quiet on this thread except for me and these crickets. So I'll chime in and answer my previous question. Turns out uninstalling and then reinstalling seems to have the same result as reinstalling without first uninstalling. That is, no settings or data gets lost, and my problem playing songs persists after both procedures. I'm out of ideas. Was hoping someone would have a suggestion.

I happen to know exactly when the problem began. On Thursday evening, April 16th, I was actively listening to music at home via subsonic over sonos when suddenly the music stopped. I have no idea what may have occurred at that moment. But I've been unable to get subsonic to stream any music since.

I'm ready to try anything. All my playlists are backed up so I have nothing to lose.

Suggestions?

Finally got this resolved as I've detailed here...
