Aarrgh! Got it working (finally). Turns out that the gnome volume control has been lying to me about the capture settings of the ADC switch (used to work in fc3). On checking with alsamixer it wasn't set! After all these years I should know better than to trust a gui ;-) So, two different problems in the end - but thanks anyhow. cheers guy Anna Klein wrote: > Guy, > > I was able to get recording to work by changing the sampling rate.
