Playback lags

[tanquai]

For some reason, whenever I playback something I recorded or imported (or anything), The track starts moving but the audio doesn't start playing until about 2 seconds later. I checked this with a pluck and the 2 green bars at the top move according to where the line on the track is, but the audio is delayed. Can someone help me figure out why? This hasn't happened before. I have reinstalled audacity, and it didn't work.

Thanks.

Sorry for the horrible description, But I figured out that the track starts playing, but the audio doesn't start until exactly 1 second later. I am using the 1.3 beta, and have only experienced this problem recently.

That sounds very weird. Is there a discontinuity in the time-space continuum or other anomalies like birds flying backwards?

The movement of the playback meters would suggest that Audacity is playing the sound correctly, but there is some major delay occuring after the data has left Audacity. Do any other media players show similar problems?
Which version of Windows are you using?
What sort of sound card do you have?
Do you have any type of "virtual sound card" or "virtual audio cable" installed?

I am using the 1.3 beta

I'd better move this to the 1.3.x part of the forum then (you posted in the 1.2.x section).

I didn't notice the sections, sorry.

Also, I'm using Vista, and Audacity is the only Audio source with the 1 second delay. I even went to the stable version and there was no delay. (I can't get used to that one though and I prefer using this one.)

Do you know what sort of sound card you are using? Is the sound card inside your computer or is it an external USB or Firewire device? If it's internal, have a look in Windows Control Panel in the "Sounds" section and it should give some clue as to the type of sound card.

Exactly which version of Audacity? (look in Audacity Help menu > About Audacity).

Just so that I'm sure about what you are saying:
If you open Audacity, then generate a tone from the Generate menu, then press the Play button - you're saying that Audacity appears to play the file immediately, but the sound does not come out through your headphones until 2 seconds later? (correct me if any details are wrong).

The only thing I have been able to find about my sound card is that it is a Realtek High Definition Audio Ver 6.0.1.5663. Also, the audio is delayed only 1 second, and it's just Version 1.3 of audacity that this happens to.

Edit menu > Preferences > 1st tab (Devices or Audio I/O)
Set "Latency > Audio Buffers" to 100
"Latency > Latency Correction" to -130 (minus 130)

It worked! Originally it was 1000, thanks very much!
