Subject: [Linux 3.8/3.9-rc1][alsa][hda] Problem with automute on HDA CX20561 (Hermosa) - Persistent even after power off

Hello folks,

All of a sudden, it worked fine in Linux kernel 3.8, I believe after booting Linux kernel 3.9 (which has ALSA HDA changes). I can no longer hear audio from speakers on laptop. If I plug in headphones audio works.

I did a hard power off, even booted into a Windows OS to see the windows kernel driver might reset the autio ports and it didn't fix this even, did the kernel driver reprogram the hardware badly somewhere? How can I fix this?

Thanks,
Shawn
