No sound in KDE [Solved]

Question

Hello.
The sound doesn't work after installing KDE, and I don't know what's the problem.
When I log in, a message appears. It says something about HDA Intel (ALC1200 Analog).
I wrote these commands in a terminal:
$ lsmod | grep '^snd'

Answer 1

Things to check -
check alsa settings as regular user
$ alsamixer
unmute any with "m" and adjust sound up on things like master, speaker, pcm
if you make changes then, as root
# alsactl store
in KDE
Settings>System Settings>Multimedia
Check Phonon>device preferences. Ensure that your sound card is at the top of the list. Use the test button here if you wish.
Check that you have a backend for Phonon. I use phonon-vlc. Install with pacman if you need it.
Post back and let us know:)
