Thanks to Mathieu Bouffard, he helped me to to workaround the issue with my mic in Acer Aspire One 1410. Issue: Somehow the ALSA driver is trying to pass to PulseAudio an stereo output that PulseAudio doesn’t understand.

Configure PulseAudio to no auto respawn when killed.

Create a file in our home directory ~/

Create the config file for ALSA: ~/.asoundrc

and last but not least, create a mini-script to launch PulseAudio using this configuration. I called it ~/pulsejack:
