Unable to play music (loads, have voice_input.wav, no sound)

[codenemisis]

The title explains my problem well enough. HLDJ loads TF2 perfectly, when I look in the console, HLDJ loads successfully, and I am able to load a song. However, when I press the hotkey to play, I am unable to hear any music, nor is anyone else. Nothing indicates that I would be playing music either(e.g. the box that appears upon speaking).

1) Does HLDJ launch the game correctly for you?
Yes.

2) Does "HLDJ Loaded Successfully" appear in console on starting the game (with no errors)?
Yes.

3) What is the console output after selecting a song, or issuing other HLDJ commands such as "hldj_next"?
hldjn
Loaded: Gold Coast - Ivory
Host_WriteConfiguration: Wrote cfg/hldj_cmd_d.cfg


4) After creating your own local server and enabling playing of audio files:
4-a) Load one of the sample audio files and perform a search of your Steam directory (without stopping HLDJ) for the file "voice_input.wav" - does it show up, and if so, where?
Yes it does, and in C:\Program Files (x86)\Steam\steamapps\myname\team fortress 2

4-b) If it exists, open it in an audio player: does it sound like the audio file you loaded?
Yes it does.

4-c) If it exists, return to the game, and enter the following into console: <code>
Does the audio file start to play?

No it does not.

5) Does voice normally work for you? If not, or you do not have a mic, have you remembered to set up any applicable options in your operating system and/or the game? *

No, I do not use voice.
What would said applicable options be?
Reading the disclaimer yields no results, I am unable to configure any options found under the recording tab, as "no audio devices are installed."

I can't say for sure as it's device and OS-dependent, but as the sticky advises, simply plugging anything into the microphone input may trigger the device to show up.

After plugging a variety of things into my microphone port, nothing has happened, I'm still unable to play music in HLDJ, and nothing shows up under the recording menu under my sound options.
However, if it helps, I'm currently running windows 7 64bit.

If "DirectSound Capture failed to Initialize ...." or similar appears in your console on starting the game, it means the voice comm system will not work for you.
Try searching for solutions on how to enable your sound card's input (i.e. right click in your recording tab -> show all devices). In game you might try "voice_enable 1" or "voice_modenable 1".
