Anyway, it's commented out. And you > already noticed the flatvolumes thing, so nothing new there.... Yeah I fixed the typo the other day :p Flat volumes shoudn't affect things at all but the other flag relating to HW volume control is telling. It basically tells me that the underlying alsa stuff is different in some what, so I'm swaying slightly on the side of it being an alsa issue in some capacity... possibly compounded by other issues tho'. I guess you could test the recording at the alsa level with some arecord commands may help confirm it but even then I'm still not sure. > I've posted to the alsa users mailing list, maybe one of the people > there has got an idea.
