Sound not working

Since I installed Arch I have been having an issue with my sound.  When I load my desktop environment (KDE) the sound cuts out after 5min with the notification "The audio playback device HDA Intel PCH (ALC898) does not work. Falling back to default". Another notification appears telling me these devices have been removed, and asking me if I want to permanently forget them.

I own a desktop computer. I have two speakers are plugged into a single audio port and a webcam in a USB port. I am not running any other audio control packages like pulseaudio.

I have already tried setting the default device to my sound card in alsamixer after my audio has failed, but it seems to want to stay set to my webcam. I have tried creating a ~/.asoundrc file to set a permanent default. Also, KDE's sound setting menu contains two copies of each device (not sure if this is relevant).

Here's the output of aplay -l

card 1: PCH [HDA Intel PCH], device 0: ALC898 Analog [ALC898 Analog]

  Subdevice #0: subdevice #0

From aplay -D plughw: I have found that card 1, device 0 is what I'm using. What do I need to do to fix this?

Re: Sound not working

Try to do something similar, i have::

cat /etc/modprobe.d/alsa-base.conf 
options snd_ctxfi index=0 model=auto vid=1102 pid=0005
options snd_hda_intel index=-2 model=auto vid=8086 pid=8ca0

you should have

options snd_hda_intel index=0
options snd<here should be nvidia hdmi output> index=1 (or -2 if you want to disable it).

Re: Sound not working

I checked, I dont have a /etc/modprobe.d/asla-base.conf file, so i made a new one. Output of "cat /etc/modprobe.d/alsa-base.conf"  :

#control for audio devices and drivers

options snd_hda_intel index=0
#options snd_hda_intel index=1

It didnt seem to work. Audio file/youtube doesnt make a sound, and now aplay -D plughw:1,0 /usr/share/sound/alsa/Front_Centre.wav doesnt work either.

Any other fixes?
