Ubuntu Natty 64 internal mic not working on lenovo x120e
Alright, I'm new to linux, I've googled for days, but I can't for the life of me get my internal mic working. It doesn't register sound in the sound preferences menu, it is not muted.
I have the x120e with the E-350. New install of Ubuntu 11.04 64-bit.
Where to start?
Thanks for the help.
First I would try: Terminal:
If not: some commands need root rights - it depends on the distribution, then you must
"sudo cat /proc/asound/card0/codec#* | grep Codec" without " "
Hi alfredo, thanks for taking the time to reply.
Codec is: ATI 6xx HDMI
alsamixer is displaying 3 possible sound cards, like this:
0 HD-Audio Generic
1 HDA ATI SB
29 ThinkPad Console Audio
Only HDA ATI SB displays any controls.
I hit F5 to display all controls. I maxed all of them including L R Capture to 100<>100.
Analog Mic Boost up to 40db.
The first time I opened sound preferences after this I noticed some movement on the input level meter. It seemed to climb and drop a bit before climbing to max. It stopped moving after that, and now I'm not sure if it is at 0 or 100. In any case, I have played around with the capture toggle (trying various levels and mic boost db levels) and my skype test call is still silent and the sound recording will not begin recording, leading me to believe I have not fixed my mic.
Something I did incorrectly or something else to try? Thanks...
When you start it, it is possible that you get an error message - ignore that and go on.
Not sure if this will help or not but I think it might.
There is a ton of information in that thread and links to more.
Or, more to the point:
Good Luck again. I really have no idea's, just pretty good search results:-)
Solved for Linux Mint (Ubuntu derivative) by updating to the latest ALSA drivers from Ubuntu Audio Dev team.
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:
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).
