Hi,
I have latest, updated arch linux with window manager as openbox which i installed from AUR.
I have also installed chromium and firefox.
Yesterday morning, browsers were running fine when suddenly audio disappeared from flash videos. Also at the same time mplayer, mpg123, vlc have no audio output.
I have searched all the arch wiki, read alsa website, arch forum for a proper answer.
I ran the very comprehensive alsa diagnostic script for a diagnosis, but i am unable to understand why audio stops while running either flash or the video players i have just installed.
I have attached the alsa diagnostic script report, which is very comprehensive.

Are the channels muted in alsamixer?
I may have to CONSOLE you about your usage of ridiculously easy graphical interfaces...
Look ma, no mouse.

First thing to check would be:
1) run alsamixer and ensure sound channels aren't muted (doubt it is muted as per your diagnostics but never hurts)
2) ensure that the proper audio device is selected
3) plugin headphones and check if audio works
Maybe some logs would help, preferably the boot logs.

No, they are not.
Flash videos were working till yesterday morning, when suddenly only audio output stopped while flash video was running. At the same time, i checked mplayer, mpeg123 , there is no audio output there aswell.

i looked at alsa.org again,
i found,
/etc/rc.d/alsa
/etc/conf.d/alsa
both scripts point to /var/lib/alsa/asound.state for configuration at boot.
cat outout of:
/etc/rc.d/alsa
/etc/conf.d/alsa
/var/lib/alsa/asound.state

I didn't think we were using rc scripts:

I don't know if removing it will fix your problem. This thread seems to be having a similar problem:
