Sound problem

[metalsandman]

Hi.

After i installed Core 6 on my machine i discovered that my sound isn't working as it shoud be. At first I used artsd to manage my sound (I use KDE) and after a while, the sound just stoped and some apps could not run ok because could not access /dev/dsp. After I disabled artsd, all my apps work, but the sound i hear is only from the right channel, and when i try to equalize the sound from any mixer (alsamixer, kmix, aumix) i just lose my sound completely.

My lspci display is:
02:01.0 Audio device: VIA Technologies, Inc. VIA High Definition Audio Controller (rev 10)

My "lsmod | grep snd" is:
snd_rtctimer 7905 0
snd_hda_intel 24537 3
snd_hda_codec 164673 1 snd_hda_intel
snd_seq_dummy 8133 0
snd_seq_oss 37057 0
snd_seq_midi_event 11841 1 snd_seq_oss

snd_pcm 80965 4 snd_hda_intel,snd_hda_codec,snd_pcm_oss
snd_timer 26693 4 snd_rtctimer,snd_seq,snd_pcm
snd 58181 13 snd_hda_intel,snd_hda_codec,snd_seq_oss,snd_seq,sn d_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd _timer
soundcore 12193 1 snd
snd_page_alloc 14281 2 snd_hda_intel,snd_pcm

Any help would be great.
Thank you.
