Hi there,
I've an HDA based chipset in a new Sony Vaio Z (Ivy Bridge). As sound as the system starts and the sound module are loaded, there's a constant noise (shhhhhhht) in the speakers. The noise change a bit if I toggle the mute button, but it's still there.
This noise stops as sound as I plug something in the jack port.
Do you mean the headphone, or any jacks no matter input or output? Also do you get the noise from the headphone output?
In anyway, please give alsa-info.sh output (run with --no-upload option). This will cover more wide range of information.
Last but not least, try the latest kernel (3.6-rc6) if not tried yet :)
