[Satellite T135, Conexant CX20582 (Pebble), Mic, Internal] Does not work - no sound goes in with recording application or skype

[***]

Internal microphone does not seem to work. It seems to run PulseAudio. In Sound Preferences the hardware is listed as Analogue Stereo Duplex. Speakers work fine -- I can hear sounds.

I have got Toshiba Satellite T110-10Z and I am also affected by this bug. Found workaround here which works: http://ubuntuforums.org/showthread.php?p=10532125#post10532125

Simply add a line to /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=hp-laptop

Several bug reports have been opened and resolved by (diwic) for different laptops but same Conexant codec.

[David Henningsson (diwic)]

Hi and thanks for the investigation.
There is an existing quirk in the driver for this model. Can you also try this instead:

options snd-hda-intel model=auto

...to see if that works equally well (or better)? Please try all inputs and outputs.

[Andrej (agno01)]

Hi,
sorry for late answer. I have tested all and it works now without any problem.

Even HDMI audio output switches on automatically which didn't before...

Thanks for advice David! :)

[David Henningsson (diwic)]

Thanks, I have now sent a patch upstream that hopefully will make it into the next version of Ubuntu!
