HP Pavilion dv9560ea microphone problem

[sloniupl]

Hello, i have a problem with stereo microphone on my laptop HP Pavilion dv9560ea. System spec can be found here:
http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c01114050#A1

after installing PCLinuxOS i managed to make it working by adding:

Code: [Select]

alias snd-card-0 snd-hda-intel
alias sound-slot-0 snd-hda-intel
options snd-hda-intel model=acer power_save=0
into /etc/modprobe.conf

But last weekend i noticed that mic stopped working again.

Sound chip in this laptop is Realtek ALC268.

Any ideas

Changes are still present in /etc/modprobe.conf?
Do you use KDE / Gnome / e17 / LXDE / (or one of the others - I'm not going to name them all  )

[sloniupl]

Hello, yes, settings in modprobe are still the same, i'm using KDE (PCLinuxOS 2011.9 minime KDE).

Hi Sloniupl.

Don't really know how to help You but I am sure that one of our gurus will be able to do so.

Hold on tight Dude.

Just one extra question: (and then I'm silent  - letting the experts talk  ):
is pulseaudio installed on your system (you can check this in Synaptic)

Not sure what the problem is, but, Googling, I see a lot of early problems with the ALC268 chipset in Linux.  Here's a link to the datasheet from Realtek:

ftp://207.232.93.28/pc/audio/ALC268_DataSheet_1.3.pdf

You are certain you're using the right driver?  I've seen the intel_hda driver somwhere before... oh, yeah.  I use it on my Latitude D620.  The sound chip for it is a SigmaTel STAC9200.  Might want to try something different?

Hope this helped some, anyway.

Later On,

hello, do you have user and pass for this ftp?? 

[horusfalcon]

I didn't need one.  Let me see if that's changed...

Urk!  Direct access to the specific datasheet is challenging.  Sorry about that.  Try getting there from here:

http://www.realtek.cz/realtek-datasheet.php?datasheet=ALC268

This isn't where I found it last night, though.  I had some trouble getting sheets to load from the Taiwan site.

Later On,
