Acer 4736Z microphone not working in Ubuntu 10.04

**butoyzki** · May 19th, 2010

hi, i am using an acer aspire 4736Z laptop and i can't seem to make the mic work. All I'm getting when I record a message is static. It doesn't work with Skype too because I tried to call Test/Echo. apart from that, everything else is ok, the sounds, etc.. do you know of any configuration which might be able to help me out?

here are some details i got from my laptop:

Code:

cat /proc/asound/card0/codec#* | grep Codec

Codec: Realtek ALC888
Codec: LSI ID 1040
Codec: Intel G45 DEVCTG

Code:

aplay -l

i did try to configure it using

Code:

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

and added

Code:

options snd-hda-intel model=acer

but it didn't help me at all. please help!

Does it work with sound-recorder?
Try gnome-alsamixer.
Gnome-alsamixer
Using Alt+F2 run dialog

Code:

 gnome-alsamixer

Use 'Edit -> Sound Card Properties' menu to enable elements.
Soundcard tab to select / adjust levels.
To install:

Code:

sudo apt-get install gnome-alsamixer

Then use pulseaudio volume control (pavucontrol) to select your mic in 'Input Devices' tab.

BTW, the correct syntax for editing alsa-base:

Code:

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

I am suffering from the same problem. I also tried to install the gnome-alsamixer and alsamixer and adjust the volume settings, but this didn't help. I am using the Acer 4763 z laptop.

Code:

abhishek@trojan-horse:~$ gksudo gedit /etc/modprobe.d/alsa-base.conf
abhishek@trojan-horse:~$ cat /proc/asound/card0/codec#* | grep Codec
Codec: Realtek ALC888
Codec: LSI ID 1040
Codec: Intel G45 DEVCTG

Code:

abhishek@trojan-horse:~$ aplay -l
