I have some live-recorded FLV’s from Flash using Speex codec in Wowza’s “content” folder. I want to play them in Media Player Classic or VLC. The video works, but I don’t get any audio. I know the audio is there because I’m able to replay and hear it via Wowza streaming, but I need to replay it outside of Flash.

I’ve already tried installing K-Lite Codec Pack Full and enabling AMR in ffdshow audio decoder as the FAQ recommends, but still no good. (Although I can’t tell if ffdshow is actually being used.) Any idea how to get the audio working?

Here’s the warning Media Player Classic gives me:

```auto

I appear to get farther with VLC, which actually shows the following under Codec Details, but still no sound, and the Statistics show 0 audio blocks and 0 audio buffers decoded:

```auto
Stream 0
  Type: Video
  Codec: Flash Video (FLV1)
  Resolution: 320x240
  Frame rate: 1000
Stream 1
  Type: Audio
  Codec: Speex Audio (spx )
  Channels: 1
  Sample rate: 16000 Hz
  Bits per sample: 16

```

It would be easiest to transcode. Take a look at this article for suggestions:
