ThinkPads used to route line-out to the dock, with a fixed 1.1dB amplifier (0.1dB increase) in the audio path, and had the volume control for headphones and speakers done in a different audio path, extracted before the line-out amplifier. The PeeCee beeper channel was routed to the headphones and speakers, only. If Lenovo tried to reproduce that with the HDA mixer but without the "Laptop Apudio Controller" the IBM thinkpads had, I wouldn't be surprised if it causes massive ALSA disruption should the firmware screw with the HDA mixer registers behind ALSA's back. Try asking the kernel to enable OSI(Linux) in ACPI... I always forget the kernel command line parameter to do that, but it is documented in the usual place. -- "One disk to rule them all, One disk to find them.
