Forgot to mention that sound does get transferred to the external speakers with .34 if I do an extra undock and redock after the resume. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

Turns out *both* the internal (laptop) and external (docking station) speakers are active after the resume. So the problem is that the internal speakers are not switched off. I have traced this to an ALSA merge: 524df55725217. Unfortunately I get boot failures when I try to bisect down into that merge.

Also, you can try to copy sound/pci/hda/patch_analog.c from 2.6.33 to 2.6.34 to check whether it works. There shouldn't be many changes in that file. thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

See files in attached tarball. Contents are: * system boot (docked) => alsa-info.txt_3[34]_docked * undock => alsa-info.txt_3[34]_undocked * suspend - dock (while suspended) - resume => alsa-info.txt_3[34]_after_resume_docked * undock - redock (this disables the internal speakers) => alsa-info.txt_34_after_resume_redocked > Also, you can try to copy sound/pci/hda/patch_analog.c from 2.6.33 to > 2.6.34 to check whether it works.
