The only solution to make microphone work is to install linux-backports-
modules-alsa-generic...
Just go to:
Menu / System / Administration / Synaptic Package Manager
And search and mark for installation:

Thanks for referring. Probably you are right - at least partly.
But at least on of the issues ( mixing a mono signal out of left and
right, as there is just a mono speaker inside) is special for this ACER

I haven't test this multiple times and after restart. But this is the first
time I get sound from Micro!. Although I boosted settings to max it could be
louder, but at least there is sound and I could plugin/out headphone multiple
times.
I think the micro jack isn't sensed, but this is not so
Don't worry about your postings - they are welcome.
Both options behave a bit strange: With:
options snd-hda-intel model=olpc-xo-1_5,dell-vostro
I got jack sensitive stereo sound on headphone. After unplug I had sound on
speaker again. After a 2nd plugin/plugout I have no speaker sound anymore -
Your result sound familiar to what I've seen during testing different
module settings, so with luck one setting might work across
distributions.
You might be interested in testing options snd-hda-intel model=laptop
,dell-vostro position_fix=0,1 too. Jack plug sensing have worked
without problems
Update: The above worked for me for a while, and now I can not get it to
work anymore. I apology for the spam.

@arno: Does it make a difference if you try options snd-hda-intel model
=olpc-xo-1_5,dell-vostro? I found this to work with Fedora 15 64-bit.

Yes, I found the drivers to be somewhat sensitive. If I run GDM3 and
liquorix kernel from liquorix.net I loose jack plug sensing (using
startx works fine however). Left and right works in head phones, but
not from internal speakers - I only have left speaker. Mic still not
tested. [Debian
Sorry about posting several times in a row, but I've found out that
options snd-hda-intel model=,dell-vostro is working in Debian unstable
with this sound card and I got jack plug sensing. The difference is the
comma between equal sign and dell-vostro. I didn't know it made a
difference so I
Thanks for your hints! We come a bit closer.
Indeed this helps to get sound out of headphone. Unfortunatly there is just the
left signal on both ears.
After unplug the headphone the loudspeaker doesn't start again.
Also the internal Micro seems to keep off working.

I tried my own suggestions this evening and installed Ubuntu 11.04.
Specifying sound card model dell-vostro did not help at all, neither
did trying one of the other ones as well. Strangely, there where no
changes in available options in alsamixer too.
When I did the same thing in OpenSUSE 11.4 -
One Tip, that helped on the Acer Aspire one 521: There is a problem with
