So I've been doing some more testing and I think this must be a timer
issue. The logic is that when I record my voice, the timing looks
strange - a 10 second recording will be shown as 5 seconds (and played
back that way).
Can anyone point me towards a good explanation of ALSA timers and how
to configure them? I have been looking around but can't find one.

Hello all
I've been trying to fix this for months on and off and have had no
luck. I'm afraid it's Skype-related, but I hope there is some general
interest.
My problem is that usually, when I record from my USB webcam
microphone (a creative Live! USB cam), the pitch is shifted upwards so
I sound like on helium.
But, sometimes, this doesn't happen. I can't identify the difference.
Can anyone suggest what I should be looking for? I tried grepping
/sys/snd*/parameters and comparing them for when the mike works and
when it doesn't; they are identical.
My kernel is 2.6.17-12; Alsa version 1.0.17; a generic Ubuntu Intrepid
setup, using PulseAudio.
Cheers
David

Have you tried setting audacity to 16000 at the bottom left of the window and
recording? What are the results? If you did and reported it, I missed it.
Sorry.

Yes, I've tried it with a number of different rates including 16000
and 48000, and it doesn't make any difference - my voice still sounds
highpitched. Similarly, if I run
arecord -Dhw:1,0 -r XXXX foo.wav
and vary the rate XXXX, this doesn't make any difference.
