Dear Readers.
My system crashed and I was forced to reinstall
PCLinuxOS-kde version.

I read once before the System Crash An instruction which say:
Write in /etc/modprobe.d
alias snd-card-0 snd-hda-intel In fact: snd-card-0 (snd-hda-intel [ALSA])
alias sound-slot-0 snd-hda-intel In fact: sound-slot-0 (snd-hda-intel [ALSA])
alias snd-card-1 snd-hda-intel
alias sound-slot-1 snd-hda-intel

The problem with editing /etc/modprobe.d is a directory
How to do that? Using Nano ? What must the file name be?
I cannot use Skype if not the sound problems are solved. MARK !! It occurs with Skype.
Alsamixer shows:
Card: HDA-NVidia (that is not snd-hda-intel)
Chip: Realtek ALC887-VD
Motherboard msi GF615M-P33
CPU0: AMD Phenom(tm) II X4 955 Processor
(four core processor)
Audio: chip Integrated by Realtek ALC887
