acer5920g built-in microphone does not work on ubuntu 8.04

Gatemaze · 08-08-2008, 05:42 PM

Hi,

I have an acer5920g running ubuntu 8.04(.1) 2.6.24-19-generic. The built-in microphone does not work. I have unmuted it from the volume control panel and I can hear a hiss sound, however, I cannot hear my own voice which I think should happen, I cannot record from audacity or I cannot talk through any voip softphone. Any ideas?

Cheers.

Follows lspci output if it helps

Well the solution was to explore a bit more the setting of the volume control and enable the recording ones.... from there onwards the mic works just fine... just in case anyone else bumps into similar problems.

zetheroo · 10-15-2008, 05:56 PM

Hi there,
I have the same chipset and am running Ubuntu Hardy but I cannot for the life of me get the mic (internal or external) to work.

Please tell how exactly you got it working...

There are MANY ppl with the same issue who have found no solution...

Thanks

For one you have to assert the "capture" controls in Kmixer (or alsa mixer or Gnome mixer) and maximize the mic boost. That was the only thing wrong in my Thinkpad.

zetheroo · 10-16-2008, 04:09 AM

OK ... I am running Hardy (Gnome) and I have activated each and everything in the volume control and pushed it all up to max.... and still I get white noise and very bad pickup.

Could you tell me exactly what the layout of your volume control is, or even take some snapshots and post them of your volume controls and capture controls etc?

Thanks

Note that the indicators below the capture are lighted. Dunno why I have two of each, maybe cuz I have an internal and an external mic. At the moment I asserted capture Skype started working.

A lot of noise doesn't sound good (no pun intended). Are you sure your hardware is OK. Did you try to boot your computer in uh... well... Windows and test?

zetheroo · 10-17-2008, 12:32 AM

OK this is strange ... you seem to have much more to your mixer than I do!?

This is my codec:

zeth@zeth-ubuntu:~$ cat /proc/asound/card*/codec\#*|grep -i codec
Codec: Conexant CX20549 (Venice)

What is your codec?

jlinkels · 10-18-2008, 08:30 AM

Funny.. I don't have a sound card accoring to /proc/sound. This is what lspci says:

00:1f.5 Multimedia audio controller: Intel Corporation 82801BA/BAM AC'97 Audio (rev 01)
Subsystem: Compaq Computer Corporation Unknown device 000b

zetheroo · 10-19-2008, 02:43 AM

Well its pretty obvious that you don't have the same Sound Card as Gatemaze and myself .... so its not much of a help.

I suppose Gatemaze is no longer watching this thread ... pity

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).
