Hi,
Thanks for looking at this.
> Does this error still occur with more recent kernel versions?
By more recent do you mean later than Etch? I do not wish to upgrade
to Lenny just now.
I am running Etch, which is kept up to date. Can I easily get a later
stable kernel to test this with?

I repeated the test and the behaviour is again as described above -
mic sounds are heard through the PC speakers but arecord records only
silence:
