OK, thanks.
I note your Acer Aspire 5253 has the 32-bit openSUSE-11.4 with the 2.6.37.6-0.5-desktop kernel installed, and alsa driver version 1.0.23 and the alsa utilities version 1.0.24.2. There are 2 sound cards identified in your Acer, where card-0 apears to be an HDMI device and Card-1 a Conexant CX20584 (which is fairly new and not very common - its the first I recall encountering).
Reference your mics, only one shows up:
ARECORD
**** List of CAPTURE Hardware Devices ****
card 1: SB [HDA ATI SB], device 0: CONEXANT Analog [CONEXANT Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
ie on card-1 (associated with your Conexant CX20584) there is a mic, … ie hw:1,0
I note this in the script’s dmesg section, but that references card-0 (your HDMI) and not card #1. So there may be HDMI audio problems, but that is not relevant to your reported problems.
63.517787] hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
Now reference the problems:
- Headset Jack does not (no sound whatsoever)
I can’t explain that. My guess is alsa was misconfigured upon booting.
When I search google for the CX20584 I note a LOT of problems and bugs reported with the CX20584. You may need to write a bug report on openSUSE-11.4 on this headset jack problem.
However I did stumble across this page when searching for CX20584:
http://git.lpclinux.com/?p=linux-2.6-lpc.git;a=commitdiff_plain;h=850eab9d1b74f4ec9de16df68f008d0a65aafae7
and it appears that the CX20584 and also the CX20585 are very similar (compatible) with the CXT5066. That is good to know, because I note this entry in the alsa documentation for the HD-Audio-Models.txt file:
Conexant 5066
=============
laptop Basic Laptop config (default)
hp-laptop HP laptops, e g G60
asus Asus K52JU, Lenovo G560
dell-laptop Dell laptops
dell-vostro Dell Vostro
olpc-xo-1_5 OLPC XO 1.5
ideapad Lenovo IdeaPad U150
thinkpad Lenovo Thinkpad
That suggests you could apply one of those options (only one at a time is allowed) to force the alsa configuration upon alsa sound driver starting, and thus maybe have a better audio configuration 
For example, lets say that you decide to start with the “thinkpad” setting on your Acer (don’t let the names of different manufacturers fool you, … you need to try ALL until you get this working - so that IS a very good place to start). Then you need to change the /etc/modprobe.d/50-sound.conf file, adding a line at the start so that it looks like this:
options snd-hda-intel model=thinkpad
options snd slots=snd-hda-intel,snd-hda-intel
# 5Dex.zfId+BEZUi7:SBx00 Azalia (Intel HDA)
alias snd-card-1 snd-hda-intel
# mnDB._gvhObmTNu3:ATI Technologies Inc
alias snd-card-0 snd-hda-intel
save the change, and then restart alsa with the comamnd:
su -c 'rcalsasound restart'
and enter root password when prompted for a password. If using KDE, don’t keep any old audio configurations if asked. Restart your mixer (‘kmix’ if kde, and likely ‘alsamixer’ if Gnome). Then test your sound, test your headphones, and test your mics. Note any one of those configurations could break your sound. No worries. Just move on to the next option. ie to test “ideapad” you replace “thinkpad” in the /etc/modprobe.d/50-sound.conf edit and restart alsa as before, restart your mixer, and test.
Note dependent on the outcome of the above, it may invalidate my observations below:
- Mic Jack Dead as well
That is possibly a bad mixer setting. I note this:

Your Acer has a lot of mics ! Mic-B, Mic-C, Mic-E, Mic-F. I note you are trying to record with Mic-C only (others are switched OFF). Are you certain Mic-C is the Mic Jack ? Perhaps Mic-C is the Webcam Mic ? Also, You have the Analog Boost in the Mixer at 0dB. My experience is that needs to be much higher . I recommend trying 30dB.
- Webcam Mic works but very faint (I have found no way to control its capture volume)
