VLC works on test computer but not on deployment computer

[rcarty]

I'm new to using VLC so forgive me if I'm asking a basic question.

I'm wanting to use VLC to receive a radio station's real-time stream full time. The output from the computer will actually feed a transmitter in the other community. I added the mmc URL to the shortcut so it starts streaming as soon as VLC runs and finishes buffering and I added the --reconnect command in case the Internet connection is lost. All of this works fine on my test bench computer but when I tried deploying it on a computer in a community it seems to be receiving the stream but no audio comes out of the speaker jack. I switched to the VU meter visualization and see movement there so it does appear to be decoding. I also have a silence detection program running on the computer and it also sees no audio signal so it doesn't appear to be an issue with using the correct jack on the sound card or a bad audio cable. On the test bench computer I set the Silence Detector input to use Stereo Mix and it's fine with that. On the computer in the community I also set the Silence Detector program to use the Stereo Mix but it sees nothing. It's Windows XP Home on both computers.

The remote community computer is working right now as only a silence detector, meaning the sound card's mic input is connected to an external radio stream receiver (a Roku SoundBridge M1001; mfr discontinued, never worked very well anyway, keeps halting and needs a reset to restore) so I know the sound card is working and the Silence Detector program can receive a signal.

Acting on advice given to someone else in another post here I set debug verbosity to 2 on both my test bench computer and the community computer and the debug looks pretty much identical.

From the remote community computer:
...
main debug: Buffering 99%
main debug: Stream buffering done (25206 ms in 24204 ms)
main debug: Decoder buffering done in 0 ms
main warning: PTS is out of range (-4176), dropping buffer
main warning: buffer is 55485 in advance, triggering downsampling
main debug: incoming request - stopping current input

(The last entry I included is me manually clicking the stop button.

From the test bench computer:
...
main debug: Buffering 98%
main debug: Stream buffering done (25124 ms in 25206 ms)
main debug: Decoder buffering done in 0 ms
main warning: PTS is out of range (-9974), dropping buffer
main warning: buffer is 46363 in advance, triggering downsampling
main debug: incoming request - stopping current input

I have of course only included a small piece of the output here but I have saved the full information in case there is somewhere else in it I should look for a cause of the computer not producing sound. Can someone give me some advice on what else to check please?

Try waveout.

Thanks for the suggestion. Neither Waveout nor DirectX produce any sound on the community computer but both produce sound on my test bench computer. Since my original post I have also noticed that both computers have the same audio hardware, Realtek AC'97.

So VLC is only program that doesn't output audio?

[rcarty]

I have not tried outputting audio with any other program, but that's a good idea - to try MS Media Player or something. This computer has been running as a single-purpose computer, only receiving audio from an external player device and running the Silence Detector program which alerts if the received stream goes silent.

Well, that was the problem. It was no sound from any source on the computer, including Windows Media Player, etc. The fix was to install a PCI sound card and all is working fine including VLC.

Thanks everyone who helped on this.
