Hi I have a Toshiba Satellite L745-S4310, i've managed to get all audio to work except the microphone. In alsamixer I do not see a volume for a mic. Suggestions anyone?
which chip is in the microphone? Seems to be an hda intel according your print screen.
It took me 4 months
to find the solution for making working the internal mic of my asus in ubuntu: I had to install a linux-backports-modules-alsa-generic package.
======content not probably for you, but just an idea how was the solution for me========
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.
So, perhaps you need an additional package, too.
Use google for finding any issue with your card/chip; perhaps this is not only a setup issue via alsamixer.
And: I came to the suspicious idea it was an ubuntu issue (not hardware) because "archbang"linux tested in live modus (USB boot) on my asus, made the front mic working without any specific setup.
So, perhaps this is an idea too, in order to exclude a hw issue, play around with archbang or others.
.. dont forget to come back here and make your mic working!
