[Solved] How to reset ALSA settings?

I run Arch with XFCE. I was editing ~/.asoundrc to finaly enable dmix and softvol for digital out. It worked but I played with it too much and now I'm not able to run alsamixer at all even when I deleted .asoundrc and restarted pc.
How can I reset ALSA back to the initial state?

$ alsamixer 
ALSA lib simple_none.c:1551:(simple_add1) helem (MIXER,'Master',0,1,0) appears twice or more
cannot load mixer controls: Invalid argument

$ alsactl init

Re: [Solved] How to reset ALSA settings?

Command 'alsactl restore -P' or the other switches might help you.
Have you tried removing '/var/lib/alsa/asound.state'?

Re: [Solved] How to reset ALSA settings?

Well, I knew that after posting I will figure it out. Your reply about debug flag give me pointer to the location of /usr/share/alsa. I realised that I have to uninstall alsa, restart pc and then install alsa. Previously I did that without the restart. So far everything look ok.

EDIT: Yes, I tried removing /var/lib/alsa/asound.state but it didn't help.

EDIT 2: Unfortunately after another restart the problem is back.

EDIT 3: Seems like after I removed alsa, rebooted and then removed asound.state it finaly went back to normal.
