Public bug reported:
I'm using a Dell Inspiron 6400 laptop. Fresh install of 7.10. Playback
works fine, however there's a mediumly loud buzzing noise in the
background when recording.
I'm recording using arecord from a console: "arecord -d 5 -f cd -t wav
-D default foobar.wav"
I've attached the result I get.
Here's some info on my hardware:
cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
lspci -v
HD00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition
Audio Controller (rev 01)

Flags: bus master, fast devsel, latency 0, IRQ 19

In the gnome mixer I get the option of "Sigmatel STAC 9200 OSS" so I
suppose that's the exact hardware type.
