Windows Media player 11 will play some audio and video fine, but then I try to play *.asx or *.wvx, I get the video but no audio.

I have reinstalled codecs, WMP 11, drivers, and tried many other things, but nothing fixes this.

Can someone please offer me some sugestions?

Thanks

Summary and focused diagnostic notes for ’s thread: the .asx / .wvx files are Windows Media “metafiles” (XML playlists) that point to one or more actual streams or files rather than carrying audio/video themselves. That explains why a different player or codec set can behave differently for the same metafile. (learn.microsoft.com)

Practical, ordered checks (minimal risk, fast results)

  1. Open the .asx/.wvx in a plain text editor and copy the <ref href="..."> URL(s). ASX/WVX are readable XML so the direct stream URL is visible. (learn.microsoft.com)
  2. Test the copied URL directly in a “plays-everything” player (VLC) or in Windows Media Player via Open URL. If VLC plays audio while WMP shows only video, that isolates the problem to WMP’s decoder/filter chain rather than the server. (images.videolan.org)
  3. Run MediaInfo on the referenced media (or the downloaded file) to see the exact audio codec (AC3, AAC, WMA, etc.). That identifies which decoder WMP needs. (mediaarea.net)

Likely causes and targeted fixes

  • Missing audio decoder or a DirectShow filter-merit conflict (WMP selects a video path but cannot connect an audio decoder). Microsoft documents DirectShow’s filter-graph behavior; graph inspection (GraphEdit/GraphStudioNext) shows which audio filter is being used. Installing a modern DirectShow decoder (LAV Filters) or using an all-in-one player avoids the mismatch; avoid piling up random old codec packs because multiple filters can create conflicts. K-Lite-type packs can fix things but use their tweak/reset tools if installing many codecs. (learn.microsoft.com)
  • If the ASX points to a stream using RTSP/MMS, a firewall or protocol rollover can make only some streams reachable; Windows Media uses RTSP/MMS/HTTP with specific ports (eg. 554/1755), so blocked ports can cause missing audio. (learn.microsoft.com)

Short checklist to record next (useful diagnostics)

  • Paste the ASX <ref> URL and MediaInfo output for the referenced ASF/WMA/WMV (codec names),
  • Note whether VLC plays both audio and video, and whether WMP plays video only.
    Those three items pinpoint whether the issue is network/protocol, codec/decoder, or DirectShow filter ordering.

WinAmp played the asx audio but the wvx video is not supported by Winamp

Download K-Lite Codec Pack and associate the codecs with Windows Media Player; that will most likely work. K-Lite has a lot of codecs so it should have you covered.
