Running Linux Mint 15 with Audacity 2.03-1. A 100 second recording plays back in 43.5 seconds. In addition to the pitch being far too high, the recording appears to be full of holes or dropouts. The 440 hz test tone records and plays back properly. I also use the latest version of Audacity on Windows XP with no problems. Windows and Linux utilize the same audio devices.
Moved to Linux forum.
Please give exact steps to reproduce the problem (I can’t see your computer 
)
Phono preamp feeds Sound Blaster Live 5.1 SB0060 sound card, which uses ALSA generic drivers. Processor runs at 2.93 GHZ.
Steve:
Sorry, but I will be away from the affected computer for about 3 weeks. Will get back to you after that.

None of the default input devices give any indication on the input level meter.
OK, but does Audacity play correctly when the defaults are selected? Try importing an audio file or generate a click track.
The only working input is: SB Live! 5.1 (SB0060) Multichannel Capture/PT Playback (hw:0.2) Line:0
If you do not already have it installed, install “pavucontrol” (PulseAudio Volume Control).
Ensure that no other audio programs are running - particularly ensure that you have no web pages open that contain sound.
Open Audacity and set both the recording and playback devices to “Pulse”.
Import a long audio file and start playing.
If sound is not heard, open pavucontrol while Audacity is playing and look in the “Playback” tab. Audacity should be listed and there should be an option to select which output to use and playback level.
pavucontrol installed and recording and playback devices set to Pulse. No input. Screenshot attached.

Sorry about that.
However, I think we’re on the wrong tack here. The problem seems to be time compression. A recording with a real time length of 3:35 is displayed as 1:36 as indicated by the time shown above the waveforms. The waveforms show very visible time compression. When played back, it does not appear that the pitch has changed. The sound is what you would hear if the phono stylus rapidly skipped grooves during playback. Since I monitor the music while recording, I know that is not the case.
So which is it? The pitch is too high on playback or not too high? 
I believe the pitch is correct. The playback skips so badly that I at first thought the pitch was higher. My apologies for the confusion.
OK, so if you generate a 30 second 440 Hz tone, does it play back smoothly as a constant tone for 30 seconds?
While it is playing, what shows on the “Playback” tab in pavucontrol?
Yes, it plays back smoothly at a constant tone.
