HLDJ does not play music, but uses the mic

[Hercludes]

Whenever I use the HLDJ, the first time I use it on a server it works just fine, but when I switch, it just uses the mic so there is no music playing, just me talkin' or whatever.
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"?
(Music file) has loaded
4) After loading one of the sample audio files, perform a search of your Steam directory (without stopping HLDJ) for the file "voice_input.wav" - does it show up, and if so, where?
it does show up, C:\Program Files (x86)\Steam\steamapps\sharludes\garrysmod
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?
Yes voice does work for me.

Make sure to test on your own server that allows playing of audio files (see sticky for the command) and test with the sample audio files. You can verify that HLDJ has loaded the file correctly by attempting to play voice_input.wav in a media player, if it exists and plays correctly, then the problem is likely the server/game. Just in case, what version of HLDJ are you using?
