hi until you get a better reply...
I suggest to delete your current /etc/modprobe.d/alsa-base.conf
Also delete any .asoundrc and /etc/asound.conf
and do a full reboot.
now look at your
output
You have mentioned you want PCH so I assume you want analog sound out not hdmi.
Please reply with what type of sound device out you wish to connect to.
Leaping ahead....if I am correct hdmi shows up as card 0 then use root powers to create file
/etc/modprobe.d/index.conf (name not important just end in .conf)

What this says to alsa....for card =0 disable it....so if it detects next card, it then gives it card=0 which will be analog.
1=enabled yes
0=disabled or no
BUT
#####
if you want analog and aplay shows PCH already card 0 your file changes to
Quote:
options snd-hda-intel enable=1,0
|
which says enable card=0 and disable card 1 for hdmi
Full reboot aplay should show only one device ....PCH
(2) I do not like KDE/plasma as it has another sound layer called phonon. You may need to check your phonon settings.

(3) then you can check your mixer levels and whether any output is muted.
Which mixer are you used to?
