I have just done a clean install of windows 7, and in trying to play a DVD i found i would get a hissing sound, i have tested CDs, audio files, online video sites, and downloaded videos; all of them work for sound, it is just burnt and bought DVDs that dont seem to be working. i have also downloaded "combined comunity codec pack" "any DVD" and "AC3 filter" to try and resolve this issue. any help would be appreciated.

Tuesday, February 10, 2009 1:44 AMi am running it on a 3 year old laptop (i have installed 2 GB of ram into it though http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00775221&lc=en&dlc=en&cc=us&product=3245654&lang=en
Thursday, February 26, 2009 6:03 PMI'm having this problem too (DVD picture is fine, but audio is a kind of repeated hissing chatter sound), on a Compaq Presario laptop. Connexant audio, ATI Radeon 200M. Was fine on XP though, just not working in 32-bit Windows 7. In addition to this, I found that, 64-bit Windows 7 lacks complete driver support for this laptop - no 64-bit sound driver for Conexant audio. This laptop is "Vista capable" and AMD Turion 64-bit CPU.
Thursday, February 26, 2009 7:28 PMIf I use VLC media player I can view the DVD just fine on Windows 7 and if I switch to Windows Media Player it still has the sound problem. So I think this safely rules out all hardware driver issues, it's WMP and/or a codec issue.
Thursday, February 26, 2009 8:11 PMIn Windows 7 M2TS and mp4 is handled by the OS using Windows Media Fondation (WMF) by the native players,
WMF is the successor to Directshow.
If you are using ext code packs, I try several times, they destroy playback in m2ts files, and or ac3. mp3 etc. natives in W7.
Depending of the pack, in my tests I need to reinstall W7. because unistalling the pack is not the solution.
Try This. Disable (especially FFDSHOW filters) in native W7 codes. Its have dolby ac3 code. Mp3 H264, divx and several more.
If you need other pack (to play ogg file or matroska) use Win7 codes 1.0.2 from Shark007, its NOT touch natives W7 codes.
