Acer Aspire 4830TG, Conexant HD Audio (Intel 6 Series Chipset Audio) No sound

Asked by reginabally

My sound card (Conexant HD - Intel 6 Series Chipset Audio Controller) on Acer Aspire 4830TG is not working on Ubuntu 11.04 64-bit (Kernel: 2.6.38-11-generic).

Installed Pulse Audio (with Volume Control). When I played music, the volume bar moves but no sound can be heard (both speaker and headphone). Tried many ways to solve the problem including rebuilding alsa. Really hope my problem can be solved as already tried many ways.

Here's information about my sound card on Alsa: http://www.alsa-project.org/db/?f=db36ac9eeda1f710a16aa99fde4adad4af9fe635

Tried:
1) Installed Alsa-Driver-Modules and rebooted.
2) Checked EAPD on 0x1b, also no sound.

One thing quite weird on hna_analyzer:
The "Mute" property in "Output Amplifier" section for both node "0x10 AUD_OUT" (Speaker playback) and "0x11 AUD_OUT" (Headphone playback) is "True". But I look at the check boxes beside the "Mute" options, they're unchecked. Could this be the cause of no sound?

I've downgraded my ubuntu to 10.04 and modified the alsa configuration (/etc/modprobe.d/alsa-base.conf) to add "options snd-hda-intel model=laptop". Now the speaker works!

But when I insert the headphone jack, the sound still coming out from speaker but headphone no sound. Any idea?
