Low audio output from rear ports on new P5WD2-E Premium board

Threaded View
I have just installed my new P5WD2-E Premium motherboard and have found
that the audio output levels from the rear ports are very, very  low.

I have tried the latest Realtek driver ALC882M from the ASUS site,
version and have also tried the latest ALC882 driver from
the Realtek site, version, dated 28 June 2006. I find the
same with both drivers. I also found it in Linux, so it MUST be the board.

With all volumes at high and all equalisations at full boost on all
frequencies, both in the Realtek HD Audio  Manager  and in whichever
media player I use, I can still only get very quiet audio levels from a
range of different passive pc speakers I have tried.
I have spent much time configuring the Realtek HD Audio Manager which I
now know inside-out and it cannot be improved anymore by tweaking the

Significantly, if I try using headphones on the front-panel audio output
of my Antec case (with the AAFC header set to Legacy AC'97 in the Bios)
I get much more  volume from the front panel connection than if  I try
the headphones on  the  rear panel  socket  having adjusted and
optimised the Realtek HD Audio Manager settings appropriately for the

I am sure it is not the fault of the speakers themselves having tested
them on other computers. The result with the headphones strongly
suggests it cannot be a fault of the output device being driven.

Obviously I will only be using simple passive speakers in the
short-term, but that is not the point.

Is there something wrong with my board or is this normal for this board?

If it is normal, why does it happen? It is certainly not normal compared
with various other on-board  5.1 audio output motherboards (including
ASUS boards) which I have used (using  the same sets of speakers!)

Can anyone help please?

I don't see any mention of the audio mixer in your post. Have you
checked it?

Yes, I have checked the audio mixer settings and put all those at maximum.
Thanks for the suggestion.

Do NOT use passive speakers.
It is a line-level output meant to drive headphones at most,
actually mean to drive an amp (either before, or inside
computer speakers) but never passive speakers.

You may have damaged it, and voided your warranty in doing
so.  Never assume you can connect passive speakers unless it
is expressly stated, it is a very rare (almost unheard of on
modern equipment) to have an onboard amp capable of driving
speakers.  The OEMs held out and put some amp chips onboard
but even they don't do it much if every anymore.
