Yes, there is. Adjust alsamixer settings to your liking:
Code:
su
yum install alsa-utils
alsactl store
Of course, if you already have alsa-utils installed, skip that, but you do need to be root to use the 'alsactl store' command. It will save current alsamixer settings in /etc/asound.state, which will be used on your next reboot or log-in.
