Hi, when I boot into that kernel, I hear, since the boot phase, short scratches repeatedly every (just a guess) 100 ms.
# cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xffa74000 irq 29
# cat /proc/asound/card0/codec#2
Could you give rather alsa-info.sh output (run with --no-upload option)?
It's a regression against, I think, 2009-11-13-19-59.
There aren't so many fundamental changes since Nov. 13. The major ones are for Intel HDMI, but it should be irrelevant in your case.
The changes in patch_sigmatel.c since then are:
d56757abc11a21996d9839c0d4e3b2c3666cd318 ALSA: hda - Replace the rest of jack-detections with snd_hda_jack_detect()
8af3aeb498197f6fdf5acc913ffe8a392cb921c9 ALSA: hda - Fix detection of dual headphones
b4e818768d50a5b7aa1635676839682bcf0691b6 ALSA: hda - Fix mute-LED sync on HP laptops with IDT92HD83xxx codecs
Could you try to revert them? The patches are found in sound git tree git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-2.6.git or linux-next.
thanks,
