Re: [Hda-intel] Toshiba U205 / HP nx6320 whitepaper

Here's a wild guess.  The HP patch code implies that the eapd bit
function is reversed.  This patch should change that behavior to logical
norm.  Test it with "model=toshiba" and let me know if there is any
improvement.  If it works, I'll add your device id and submit an
official patch.

Also, post the output from "lspci -s 0:1b -vn", as this will give us the
proper sub-vendor and sub-device id's for the driver.
