Thread: (Lucid) internal mic not working ALC262

on lucid lynx 10.04 got internal microphone of vaio vgn-ns11z work on intel hda sound card (lspci says 'rev 03') with

#cat /proc/asound/card0/codec#0 | grep codec
codec: realtek alc262

start terminal (applications > accessories > terminal) , add following line /etc/modprobe.d/alsa-base.conf so:

#sudo nano /etc/modprobe.d/alsa-base.conf

enter password proceed. @ end of file, add following line:

options snd-hda-intel model=toshiba-s06

note: if see b's in brackets, leave them out!

reboot machine, , internal microphone should work. if not, start terminal (applications > accessories > terminal) , start alsamixer (just type alsamixer , press enter). check whether capture settings correct (press f4 see capture settings, use sideways arrows select column , up/down arrows modify volume accordingly).

note: if activate mic setting in playback screen (press f3 or f5) might annoying echo/feedback/whistling on microphone, leave set low setting (zero works fine).

addendun: incidentally, above solution solved skype 2.1 microphone problems, after few reboots. first try sound recorder working. try fix skype.

important: install skype 'partner' repositories (enable them removing # in front of lines containing word partner (search ctrl-w in nano) in file /etc/apt/sources.list, refresh package cache 'sudo apt-get install update' , install skype using 'sudo apt-get install skype').

sometimes, may need fix pulse audio settings, default mixer program xorg window manager in ubuntu. (in terminal, 'sudo apt-get install paman' , under applications > sound & video tweak pulse audio settings.) terminal-based alsamixer can set recording settings desired levels, regular volume managers fail.

more not, being unable use internal microphone sound driver problem. solved looking sound card 'lspci | grep audio' (in terminal) , searching fix specific sound card.

intel hda line of cards, card's internal chip, known 'codec', shown in post above. model code have add end of /etc/modprobe.d/alsa-base.conf in /usr/share/doc/linux-doc/sound/alsa/hd-audio-models.txt (install file entering 'sudo apt-get install linux-doc' in terminal. may need unzip file first using gunzip).
