Sounds like you recorded at 44.1 and are trying to playback at 48.
Have you tried changing the project sample rate in audacity? (at the
bottom left)

Yes, that is what I thought too. But I used the "-f dat" option while
recording, which according to arecord's manpage should have given me 48000
Hz sampling rate. Based on this, I had converted au->flac by specifying
48KHz sampling rate.
In audacity I had to reduce the speed (Effects menu) by around 8% to make
the audio replay properly ... this corresponds to 44.1 KHz. (If I forced
audacity to 44.1 KHz from its GUI (lower left), it wouldn't play the track
at all)
So the "-f dat" option of arecord actually recorded at 44.1 KHz and not at
48 KHz !?
Here is the exact command that I used:
$> arecord -D plug:hw:1 --duration=6300 --file-type au --format=dat
--nonblock `date +%Y%m%d%H%m%S`.au
