Headphone not working since last upgrade

Headphone (in front panel) is not working since last kernel upgrade. Alsamixer shows the options in grey.

Motherboard is Asus M4N78 PRO with nVidia MCP78 HDMI chip.

Any idea?

Re: Headphone not working since last upgrade

Same problem here.

alsamixer shows the "headphone" bar in grey as in the picture linked above and no sound is available.

My board is an Asus M4N78-E. I use the onboard audio chip (HDA ATI SB, Chip is a VIA VT1708S).

@edit: corrected name of mainboard and audio chip

Re: Headphone not working since last upgrade

I did not change my configuration that was working since I set up the system about six months ago.

There doesn't occurr any error message, simply the headphones that are connected to my front panel have no more sound and alsamixer shows the bar for headphones grey as it is visible in the picture linked above.

I played around with module options in /etc/modprobe.d/modprobe.conf and set "model=asus" but that didn't change anything.

Do you have any ideas? Help would be appreciated.

Some additional info:

Re: Headphone not working since last upgrade

In the end, have you found the solution to this problem? It seems that I also have that problem.

Codec: VIA VT1708S

and no sound on front panel. I've tried with:

options snd-hda-intel model=6stack

as I saw in few posts over Internet. Also gray headphones jack in alsamixer. Sound worked fine in Ubuntu.

lspci -v | grep -A11 Audio

Re: Headphone not working since last upgrade

I found this problem to be related with kernel upgrade. Using kernel26-lts solved this issue (in my case).

Oh... I just tried kernel26-lts but then I get lot of other problems like installing the nvidia drivers and so on...
But, It's good to know, thank you.

Unfortunately sound remains probably the biggest desktop Linux problem. Mine problem is I can't go back to Ubuntu after trying Arch it's so incredibly fast and clean and a rolling distro the concept that I really like. May I ask which distro you use for desktop now?
