Summary:                    Very annoying acute sound recorded from line-in with
M5455 chip
Description: 
I'm using an ULi integrated sound chip, which reports as a M5455 device,
and which works very nice with the intel8x0 driver for playback, but
recording sound from line-in input gives corrupted sound with a very acute
background sound, except when source gives silence.
I have another motherboard (very older, and still with intel8x0 compatible
chip), and it gives the same result.

Does the problem only occur when using the OSS emulation layer?

Yes, it seems to be OSS related only.
I didn't try to get record using alsa device, since it seems to only
understand OSS devices. However, I tried to record a film with mencoder,
using hw.1 ALSA device and 44000 Hz, and it successfully record the film
sound.
