Bug Description

Binary package hint: pulseaudio

Fresh installation of Ubuntu 10.04.

The built in mic on my HP laptop doesn't work (it used to work fine under -karmic) while an external microphone plugged in the 1/8" mic input works just fine.

I have no manual option to select internal or external mic under gnome-volume-control.

I've found out that in Ubuntu 10.04 there is no possibility to manually select either the internal or the external mic but autoswitching is done based on jack presence (i.e. when an external mic jack is plugged in, the internal microphone is muted and only the external one works; and when no external mic is plugged in, the internal microphone should work).

Anyway, in my case an external microphone connected to the 1/8" jack input works but when I disconnect it, the internal mic doesn't work at all.

Please see the attached file (hope it helps).
Also please let me know what other information is relevant for you (and how to retrieve it).

- Release: Ubuntu 10.04 LTS
- pulseaudio: 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14
- alsa-base: 1.0.22.1+dfsg-0ubuntu3

Thanks in advance

Hi Daniel

Even if I increase both Mic Boosts (using alsamixer) nothing changes :(

I think that I've just found out why it says "Couldn't find package": it seems that the latest linux-alsa-driver-modules need to be built (pls see attachment).

I'll try again later today.

So I must have misread your previous post.
What did you mean exactly by "You could try linux-alsa-driver-modules-$(uname -r)" ?

fab, l-a-d-m are only built for stable releases and -updates (and when
available, for current devel branch's current kernel). You'll need to
use -21 instead of -22 if you're using Lucid (minor version difference
for Karmic, but you get the idea).

fab (fab-head) wrote : Re: Lucid Linx: built in microphone doesn't work anymore

Got it, thanks.
I've reverted to kernel -21 and installed linux-alsa-driver-modules version 2.6.32-21.201005020600

Unfortunately, that didn't help as I still cannot use the internal mic.

Is there anything else I could try?

Hi Daniel,

It seems that I've found a temporary workaround to this bug.

I've tried all the possible options for snd-hda-intel in /etc/modprobe.d/alsa-base.conf and in the end I had some success with "options snd-hda-intel model=toshiba" (even if the laptop brand is HP).

In this case the mic autoswitching doesn't work (i.e. the sound input must be selected manually), but I now have a selection box under "gnome-volume-control > Input" which lets me choose either Line-in, Microphone 2 or Microphone 1.

Please let me know if you need any further info.
Thanks in advance!

Hi, same problem here.

I'm on a HP Pavillion tx1499us
with snd-hda-intel (name nVidia Corporation MCP51 High Definition Audio (rev a2))
(Chip Realtek ALC861-VD according to alsamixer)

- Release: Ubuntu 10.04 LTS
- pulseaudio: 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu14
- alsa-base: 1.0.22.1+dfsg-0ubuntu3

In my case, gnome-volume-control offers only one choice for "sound input":
"Interanl Audio Analog Stereo"

But the internal mic is not working, only external mic works connected to jack.

In my case I've found a different workaround than fab, I just opened alsamixer in a console, went to the Capture tab with F4, and there it was the "Input Source" selector, letting me choose between "Front Mic" (which corresponds to external jack) and "ATAPI Mic" (which enables built-in mic)

After choosing "ATAPI Mic" in alsamixer, no change is seen in gnome-volume-control , but internal mic works as expected.

So in my case, the snd-hda-intel driver seems to behave correctly, but seems like gnome-volume-control is "oversimplified" and doesn't show all the available switches (while they do appear in alsamixer)

Cheers!

I had a similar problem (no mic after upgrade to Lucid). I tried to change various alsamixer settings but finally realised that I actually just had to use System->Preferences->Sound instead of alsamixer.

Also, I noticed the following post

In that case an upgrade to alsa 1.0.23 solved the problem
This upgrade is also recommended by

Is it a general problem of ubuntu 10.04 that it installs different versions of alsa?

Hi,
I have the same problem. My internal mic for recording is somehow disconnected, including in applications like skype. Using alsamixer and boosting the volume allows me to hear that the mic is working but that's all I can do with it. And this since the upgrade to 10.04.

Before pulse, I was able to individually select my devices: choose the usb speakers to output the sound from one application, while listening to music on my headset using another application, and so on. Now I'm not sure my usb works independently (don't have it with me so I can't check). Alsamixer allowed before the choosing of the input devices. Now, as has been said before, it doesn't. I'm not sure If there are any files i should attach. If anybody knows, please let me know.

Is there any manual or tutorial anywhere explaining the interactions between pulse, alsa and the devices, in such a way that it provides a practical view on how to indidually manipulate them, or at least who is controlling what? How can we check to what device are the computer volume controls connected? Can we choose?

The internal microphone work fine, but when I try an external one in the mic jack input, the internal still working and the external doesn't.
I tied to change the device but nothing seems to work. (Analog stereo duplex ; Analog stereo output ; Digital stereo (IEC958) output + analog stereo input ; Digital stereo duplex (IEC958) ; Analog stereo input )

@Snake, have you tried dealing with alsamixer?
In my case, opening alsamixer and hitting F4 shows me the recording
controls, one of which lets me choose between input sources, using the
up and down arrow keys.
To open just type "alsamixer" into a console, without the quotes. Then
navigate with arrow keys and F3, F4, F5.
Cheers!

Hi there,

FYI

I've just upgraded to Maverick and the issue is still there: the internal mic works, while there's not input when I connect an external microphone.

I still have to add "options snd-hda-intel model=toshiba" to alsa-base.conf in order to get any input from an external mic,

This way the mic autoswitching doesn't work, but this gives me a selection box under "gnome-volume-control > Input" which lets me choose either Line-in, Microphone 2 or Microphone 1.

Just go to:

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).
