Hi,
can you please provide a sample file (30 seconds would be ok) - you can upload it as attachement to this forum.

on my side I can not see this issue with similar files.
Can you please also list down the installed Codec Packs - some codec packs do changes deep in Os and sometimes break other applications.

please also provide all related info:

Thank you for the reply.

Out of sheer frustration, I have uninstalled Power DVD v11 and tediously reinstalled several upgrades' worth of versions to get back to version 10, which plays the AVCHD audio fine, even up to the most recent Patch 2916 installed via the workaround posted elsewhere here.

The only PC that I installed version 11 on was my home theater PC, which runs on Windows Vista with all Microsoft updates installed and up to date.

Intel D975XBX2 motherboard, 2.40Ghz Quadcore, 4GB RAM, nVidia GeForce GTX 260.

The audio is fed necessarily via analog connections for 7.1 surround sound from a Creative SoundBlaster X-Fi Platinum Fatal1ty Champion Series to a Denon amplifier. Analog is the only choice because there is no digital / optical connection from the soundcard available beyond two channel stereo. Like I already mentioned, other files, such as copyrighted DRM .WMV files that I legally purchased from the Amazon HD store, play the audio fine, even in 5.1 surround, so this seems like an AVCHD / H.264 / MPEG-2 / MPEG-4 codec issue. I threw MPEG-2 into that mix because an edited AVCHD video that I saved as an MPEG-2 also would not play any audio.

See attached.

Here are some apps that may influence codec installs:
VLC
Quicktime
DivX Plus
Xvid
VideoReDo
Ulead DVD Movie Factory 6
Roxio Easy Media Creator 10
Hauppauge WinTV
Amazon.com Video Service Player
Winamp
Real Alternative
Windows Media Center

Thing is, the AVCHD audio works fine in Power DVD 10, but not 11, so I would think that points most likely to a problem with version 11, all other things being equal.

Not sure if that's the page you intended, as that is a list of fixes for the latest patch.

I think I'll have to continue to use version 10 until the bugs in version 11 are worked out. One of the main reasons I upgraded to version 11 was that the remote control via my Android phone looked interesting, but as others have pointed out here in the forum, it only works with the mouse control, if it works at all, and nothing else (buttons, disc controls, etc.). FWIW, I have a Sprint HTC EVO.

Hi,

I can playback the file (with audio) on my system.

can you please upload your DXDIAG - I guess it's might be related to your Audio Configuration...

Thank you for suggesting looking at the DXDIAG report. It gave me a couple of ideas:
1) Update the Xvid codec
2) Update the driver for my soundcard. The new version, which came out a couple months ago, for whatever reason did not auto-update (it's not very reliable). The release notes had a bit of an obscure reference to fixing a bug when using Power DVD 8.3:

--------
Fixes:
Resolves the following issues:
•System taking more than two minutes to shut down.
•PowerDVD® DX 8.3 (Dell® version) not working properly.
•Passthrough of Dolby®/DTS® audio to an external decoder not working with Windows Media Player 12.
--------

So, I decided to give Power DVD 11 Ultra another try, and the AVCHD AUDIO WORKS NOW!!!

While I cannot precisely pinpoint with certainty what resolved the problem, some combination of updates finally worked.

Thank you for your help and suggestions!!!
