Bug Description

I observe a somewhat buggy behavior in comparison to 11.10. I have a desktop PC with audio out on the back (I use it for speakers) and audio out in the front (used for headphones). I have both: speakers and headphones connected all the time. In 11.10 it used to provide output to both, so I just switched the speakers off when I wanted to use the headphones.

No the behavior is as follows:
1. Boot Ubuntu 12.04 with speakers and headphones plugged in.
Result: Audio only on headphones
2. Unplug headphones.
Result: No audio heard at all.
3. Unplug and plug speakers.
Result: No audio heard at all.
4. Plug headphones.
Result: Audio only on headphones.
5. Suspend to RAM and wake computer.
Result: Audio on both: speakers and headphones.
6. Unplug headphones and reboot.
Result: Audio on speakers.
7. Plug the headphones
Result: Audio on both: speakers and headphones.

The bottom line is: if I want to have sound on speakers I need to either boot Ubuntu with headphones unplugged or boot normally (with both speakers and headphones plugged in) and perform suspend-to-ram and wake procedure.

I have an update on the above scenario:
5. Suspend-to-ram, unplug speakers and wake computer.
Without unplugging speakers I still get no sound after waking the computer.

I have been doing some testing and by adding 'options snd-hda-intel model=auto' to /etc/modprobe.d/alsa-base.conf then rebooting my computer I see in the sound output

Digital Output (S/PDIF)
Built in Audio

and I can select Analogue modes for duplex, 4.0, 4.1, 5.0 & 5.1 with Analogue Stereo input.

I have sound out of Headphones only.

Chaning the /etc/modprobe.d/alsa-base.conf options snd-hda-intel model=auto to model=acer or acer-aspire. Everything works correctly apart from I am unable to select the audio mode for surround. This was working fine in Ubuntu 11.10

Forgot to mention I have an Acer-Aspire 8930 where I have seen a post from where it suggests that the options snd-hda-intel model should be set to auto for my device.

Shanekpiper (shanekpiper) wrote :

When snd-hda-intel model is set to acer or acer-aspire, the test sound function does not work, but I have only stereo sound. Not all speakers play sound only front left & right.

Dariusz - I can see that you have upgraded from 11.04 to 12.04
InstallationMedia: Ubuntu 11.04 "Natty Narwhal" - Release amd64 (20110427.1)

Even if you did a fresh install I am sure the problem will still remain, as I did a clean install of 12.04 beta 1

Shanekpiper - Yes, I've originally installed 11.04, but later I've upgraded to 11.10 and eventually to 12.04. It was working correctly all the time up to upgrade to 12.04.

Shanekpiper (shanekpiper) wrote :

As a temporary fix even though it reduces the speaker output to just stereo left and right, try adding the following to alsa-base.conf

Open up a terminal:

sudo gedit /etc/modprobe.d/alsa-base.conf

add at the bottom of the conf file:

options snd-hda-intel model=asus

Save it and then restart your computer, this should work, but I hope they come up with a solution for all.

Thanks Shanekpiper.
Unfortunately adding
options snd-hda-intel model=asus
to file
and rebooting afterwards did not help.

After the reboot with headphones plugged in I can't get any output from speakers no matter whether I plug in or out the headphones jack.

I consider this invalid now. I think it was the fault of my BIOS settings. I have changed the Onboard Devices / Front Panel Select setting from 'AC97' to 'HD Audio' and the jack detection behaves as expected:
1. I boot with my headphones plugged in to the front panel -> I have no sound through speakers, but I hear it through headphones.
2. I unplug the headphones jack -> the sound is heard from the speakers.
