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

Sounds like what I have had happen when my sound card was set for one
frequency and my program for another. (This is a general comment, I have
never used skype.)

That sounds about right... it isn't actually just skype, I have the
same problem recording sound in audacity.
Can anyone point me to a way to set the recording frequency for my USB mike?

I should add that starting pulseaudio from the command line gives:
W: alsa-util.c: Device hw:1 doesn't support 44100 Hz, changed to 16000 Hz.
W: alsa-util.c: Device hw:1 doesn't support 2 channels, changed to 1.
where hw:1 is my mike. The same works whatever I put in
/etc/pulse/daemon.conf. I guess the mike just only provides one sample
rate. So, how can I make the rest of my system etc. use 16000 Hz?

Ouch, are you intending to use that mic for audio recording (music)?
At the bottom left of Audacity you should see a Project Rate selection box.
(As an example.)
There may be other options. This is just off the top of my head.

Yes, the mike definitely only works at 16000 Hz. At least, that's what
it reports.
But this shouldn't be a problem, right? pulseaudio should resample it
to 44100 Hz. That doesn't seem to be happening, though.

I can't tell you that, but one thing to try is to change the freq in your app
from 44,100 to 48,000 and back and to see if you notice a difference.
mike?
