Which kernel are you using?
I'm using 3.4.5 with gentoo patches.
Pin Default 0x411111f0: [N/A] Speaker at Ext Rear^^^^^^^^^^^^^^^^^^^^^^^^^^^^^This is the reason. The driver checks the pin config set by BIOS, and it leaves this pin unused. Could you give alsa-info.sh output for more checks?
I included the link to alsa-info in my original mail. ;)
This is the link: http://www.alsa-project.org/db/?f=e297bdda4fd099425516c7c831e28a2c7d8ae6b6 I append the info below this mail.
Thanks.
Basically you can build your kernel based on 3.5, cherry-pick the commit 108cc108a3bb42fe4705df1317ff98e1e29428a6, then pass model=lenovo-dock option, or apply the patch below in addition.
Let me know if it really works.
