Microphone not working in Optiplex 980

[Ara Pulido]

The microphone test is failing in the Dell Optiplex 980
This is quite similar to bug 412862, but opening a new to better track it.

Audio HW:
Intel Corporation 5 Series/3400 Series Chipset High Definition Audio

TODO:
 * Someone with access to the HW to check if the bug exists in Natty

The microphone seems to work fine on an Optiplex 980 running Natty, tested with image 20101130. The hardware is the same as originally reported in this bug, ie Intel Corporation 5 Series/3400 Series Chipset High Definition Audio. However, note that the sound preferences application provides a drop down of two possible connectors for the input device. Microphone 1 doesn't work but Microphone 2 works just fine.

[Ara Pulido (ara)]

@diwic: with this new information, could you continue working on the bug? The default setting should work

[David Henningsson (diwic)]

I'm still missing an answer to at least the first question:

1) Is this internal mic / external front mic / external back mic, or all of them? What mics are actually present?

[David Henningsson (diwic)]

Ok, I went to visit someone and it turned out he actually has an Optiplex 980 standing here, so I can answer my own question.
I can get microphones working in both Maverick and Natty, both front and rear jacks. However, it requires manually turning the mic boost up in alsamixer, as PulseAudio does not seem to handle this properly.
Can you confirm this behaviour?

[David Henningsson (diwic)]

Alsainfo for Maverick

There is only one capture subdevice but two capture volume controls/switches and two input sources

if HDA controller does not have enough DMA for two capture subdevices for multistream capture , why the driver build two capture volume controls /switches and "Input Source" controls

Will the pulseaudio packages at https://launchpad.net/~diwic/+archive/pulse-mixer resolve this issue?

[Andy Whitcroft (apw)]

Is anyone able to test the packages offfered by David? If we could get some testing we might be able to get this fix applied.

[Kemel Zaidan aka Legendario (kemelzaidan)]

I have the same chipset on a Lenovo machine and my microphone doesn't work too.

[David Henningsson (diwic)]

As the pulse-mixer now has been released into Natty, I think it should work out of the box now (in Natty). Please confirm.

[Chris Van Hoof (vanhoof)]

Updating the severity of this bug to high as we've not received feedback even on natty. Once this has been verified we can evaluate the potential for a fix in Maverick.

[Chris Van Hoof (vanhoof)]

Marc -- Can you verify this bug has been addressed in Natty? From there we'll look into what it will take to bring this into Maverick.

Regards,
Chris

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

@Chris

I can verify that the microphone does work in natty in the 20110317 image.

[Chris Van Hoof (vanhoof)]

Thanks Marc

[Michael Kopytin (utkapodsousom)]

I simply changed input type to "analog microphone" and it fixed.) Silly, yea?)

[João Miguel Lopes Moreira (jmlm-1970)]

The only solution to make microphone work is to install linux-backports-modules-alsa-generic...

Just go to:

Menu / System / Administration / Synaptic Package Manager

And search and mark for installation:

linux-backports-modules-alsa-generic

tip: if you have multiple versions click on the first and read the description which should inform what name to install...

If after the reboot and mic mute is off, still does not work, just go to terminal and type:

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

and add or change the following:

options snd-hda-intel model=auto enable=yes

Then Ctrl+X, type Y to write and exit, reboot and mic will work.

Bye and have lots of fun with Ubuntu (the best).

This bug affects Ubuntu 10.10, Maverick Meerkat. Maverick has reached end-of-life and is no longer supported, so I am closing the bugtask for Maverick. Please upgrade to a newer version of Ubuntu.
