Good evening. I am the lucky owner of a nice Compal EL80 laptop, sporting an
Intel HDA audio controller with realtek alc883. Here is what I get with lspci -vvv:

I had very elementary operativity, but missed much, including for example
microphone boost. I applied the following patch:

As you can see, I did various tests with possible 'alc_config_preset'
structures. I could only copy from other existing examples, since I have no
idea how you would obtain the correct values to insert there. With the first
example, the only one that is commented in (copied from LAPTOP_EAPD), I could
obtain a working microphone boost. The thing is far from perfect, though.
Suffice to say that I find the main volume in the cursor labeled 'Surround'
in alsamixer.
Is there any instruction about how to obtain the right information to
configure this laptop of mine? Can you help? In this case, what other
information may I provide?
Thanks in advance
