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, Takashi _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
