CentOS

Just got, with help from a friend, CentOS up and running. And everything seems perfectly fine so far except this problem.
I have ASTRO A50 wireless headset detected properly in sound but there is no sound coming out of headset.
When I select monitor as output it works fine sound is there so figuring what's going on.
It did work right after installation but at some point, it stopped.
Any idea where to even start looking at what could be an issue?
Thanks

Ok sorted out.
Booted back to win to wrap up something and headset was silent there as well.
Was simply a matter of unpairing wireless headset and base.,
Did the pairing and all good works back in centos as well.
False alarm
