Yes, "toshiba" was added by me when I tried to fix the microphone
OK, I commented it out and restarted pulseaudio. Not sure if I restarted it correctly, I used those commands:
Then I run
gksu /etc/init.d/pulseaudio stop
gksu killall pulseaudio
gksu /etc/init.d/pulseaudio start
which resulted in
Then I tested Sound Recorder. It was it was working like a charm.

Then I tested audio call with Empathy. It was quite bad: a lot of clunking like "chuk-chuk" on another computer (also running Ubuntu), some disruption, in general it was very hard to understood. The sound from another computer was heard excellently on this Acer.
Then I tried video call with Empathy. Which killed the microphone again. It does not work (e.g. in Sound Recorder) until I reboot
Here is my updated result of alsa-info.sh:
