No music, only voice.

[NinjaRun09]

I am in need of some assistance. On TF2, I try playing some music(Converted), but all I hear is my voice. I set the Audio Directory to a file in my desktop called HLDJ with all the Wave Sound files in there. In-Game I've typed "la" in the console and picked a song. Typed that in, and typed hldj_playaudio_on, and like I said, its just my voice. Any solution?
*EDIT* 1. HLDJ Launches TF2 for me.
2. HLDJ loads successfully

4b.Yes
4c.I put it in the console. Still no music.
5.Voice does normally work for me. Yes I have remembered. Yet in the end, still have my voice.
I just don't know what went wrong.

4c -> no -> see sticky on setting the appropriate server variables.
note: test with the sample audio files.
