Hi Everybody,
This was posted as a reply to another thread but i tought it might help others who have a problem with the internal mic , so i'm posting it here as a separate thread.
If the moderator finds that it is not needed you are free to delete it.
For a very long time i was trying everything to make internal MIC work on my laptop (Aspire 6930g)
Did all the possible input in /etc/modprobe.d/alsabase.conf and NOTHING worked.
All i can hear from the internal MIC was a static noise (it's a digital stereo microphone in those laptops).
So, here it is the fix for it.
It is guaranteed to work with "Vanilla" Maverick Meerkat and Lucid Lynx and probably with Karmic etc with ALSA 1.0.22 or later.
You DO NOT HAVE to edit anything in /etc/modprobe.d/alsabase.conf BUT if you want you can input options snd-hda-intel model=auto (with me it works better with model=auto or acer-aspire-6530g).
You have to EDIT as root
Find in it:
IMPORTANT : REMOVE the ; in front of the first 3 lines
SAVE, Reboot and that's it.
It should work now.
It took me 2 months to realize that this was the problem since pulseaudio is poorly documented (or i could not find any on those settings)
Now with default-sample-rate = 48000 there is only a little static on the internal MIC so maybe someone could suggest better sample-rate??
I am glad if this is going to help anyone.
With those settings Ubuntu MAverick (thats what i got is 100% compatible with this laptop)
Just as a small note that DSDT needs to be fixed on it for the battery to be corectly recognized (but that is another story).
So if it helps, post your results for me and others to know.
Take care
,
