The same happens to me. Using the suggested sequence of commands allows
recording from the mic.

As Jean-Louis Biasini said, the trick consists in switching the input source first to CD and then back to Mic

> Mic Playback Switch sounds unreasonabele?

I think that it refers to the switch that enables or disables hearing the sound from the mic through the speakers.

It's an embedded sound card in a laptop computer. Some data follows: 

$ dmidecode

BIOS Information
        Vendor: FUJITSU SIEMENS
        Version: 1.08C

Base Board Information
        Manufacturer: FUJITSU SIEMENS
        Product Name: AMILO Pi 1505

$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

$ lspci -vn | grep 00:1b.0
00:1b.0 0403: 8086:27d8 (rev 02)

$ cat /proc/asound/card0/codec#1 | head
Codec: Realtek ALC861
Address: 1
Vendor Id: 0x10ec0861
Subsystem Id: 0x15840000
Revision Id: 0x100300

>>From the information in /usr/share/doc/alsa-base/driver/ALSA-Configuration.txt.gz  it seems that there are some tweaks for some codecs in Fujitsu Computers, but none for the ALC861 codec. Maybe we need an specific tweak for the ALC861 too.
