Bug in Catalyst 12.4

Looks like you folks have a bug in the latest version of Catalyst.  I just downloaded the latest update on 4/29, after being prompted to do so, and if I turn my monitor off and back on, the audio over the HDMI cable dies with the device showing "unplugged" in the audio properties.  I have to unplug the HDMI cable and plug it back in again for the audio to recover.  Simply disabling the device in audio properties and enabling it doesn't work.  It's only the audio portion that is unable to recover automatically after the monitor is turned off and then back on.

I did a system restore, went back to the previous version of Catalyst and the problem went away.  I can turn the monitor off and on all I like and the audio stays awake.

Since you haven't gotten any replies on the forums yet, try contacting AMD Support here:
If it's not a bug, they can help resolve the issue. And if it is a bug, they should know the right person to report it to.

Same for me, updated to 12.6, and it seems fine, issue seemed
resolved, however, shortly after the update, the problem returned.  If
boot up my system and the HD TVs are connected (via HDMI), all is fine, but if
I change either of the HD TVs to some other mode, say normal TV, Xbox360, DLNA,
etc., and then return to computer monitor mode at some point, I sometimes lose
the audio.  If I turn off one of the two HD TVs and turn it back on, I
almost always lose audio but not video.  So as far as I am concerned, the
issue still exists.  I don't recall 12.2 or 12.3 ever doing this.

I have a Visio E320VL (VIZ0067) and a Sharp Aquos (SHP105B)
connected to two ATI HD 5450s, one per HDTV, but the issue also happens with
the onboard 4290 as well, for the system in question.  The only solution I
have found is to go into the Catalyst Manager, and force the given TV to be
reinitialized via the HDTV EDID override option, this seems to cause Windows 7
64 bit (well, the Catalyst driver) to rediscover the HDTV completely, and thus
restores the audio connection, what is odd is the video connection never fails
to respond, but ATI must understand the specifics of this better than I.
I only sometimes get the dialog popup that says I that I am using a DVI-to-HDMI
connection, which is bull, everything is straight HDMI from video adapter to
each HDTV.  But this maybe a clue as to what is going on?
