Omxplayer sound issue on raspberry pi

[mangelic]

Hi everyone. I built the omxplayer package (https://aur.archlinux.org/packages/omxplayer-git/) two days ago and when I play a video I cant get any sound through my speakers. I followed the installation guide in Arch wiki (https://wiki.archlinux.org/index.php/ALSA) I have installed the modules and unmuted with alsa packages. Then I made the speakers test and I can play music with mplayer function. I don't know if there is something wrong with my config files but omxplayer plays video without sound. There is no error message so I can't post anything like that. I wonder if somebody could help me.
Thanks and have a nice day!
