Closing this bug owing to age (not least, age of the hardware; also, the
kernel will have moved on) and lack of interest.

Title:
Samsung NC10 internal mic always hissing
Status in “alsa-driver” package in Ubuntu:
Invalid
Bug description:
On my Samsung NC10, with RealTek ALC272 sound card, recording from the
internal mic always comes with a substantial hiss, however I fiddle
with the settings. Under Windows, there is no problem. This bug is
similar to #448859, but it is not the same: I have no trouble making
audible recordings, and I do not have to turn up the input gain (I
have the input set in PulseAudio to "unamplified"). The problem is
simply that there is always hiss on the input.
