I have just tested this issue on the Dell Mini 9 and it appears to now be fixed. I had always believed the stuttering to be due to the CPU being maxed out. See my post on this duplicate bug https://bugs.launchpad.net/ubuntu/+source/alsa- lib/+bug/275046/comments/26
On my fully up to date Karmic install, recording using gnome-sound- recorder now works, even when encoding to ogg. The CPU is no longer maxed out, (both CPU threads are about 50%). I am only guessing here, but I expect that the process of recording from the mic, then being processed by pulse audio and finally encoding to ogg was previously too much for the ATOM processor. I would guess that the processing by pulse audio included sample rate conversion and mixing. Therefore in Jaunty, recording worked when either removing pulse, or simply by recording directly to wav rather than to ogg. Maybe there have been improvements to pulse audio that reduces the load on the CPU caused by it's processing, maybe it no longer needs to perform sample rate conversion or mixing. I would like to find out if anyone knows. But anyway it appears to be working so excellent work, whoever was involved!
