Comment 4 RHEL Product and Program Management 2012-05-03 04:40:35 UTC
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Similar problem, mute Master through alsamixer works but unmute not. Pulseaudio volume control still shows muted, sound not audible.

Muting Headphones channel, mutes also Master but unmute leave Master muted.

HW: Realtek ALC889
