How to play raw audio data encoded with PCM a-law

[limpid2009]

I want to know how to play raw audio data file encoded with PCM a-law, please give me a help.

I insert a wave header data into the raw data file, VLC may work well. But I think the VLC can work well with the raw PCM a-law data file by provide some parameters to VLC in command line.

Thanks a lot.

Use the raw audio demuxer, yes.

Thank you very much.

I have tried the following command:
vlc --demux=rawaud --rawaud-channels 1 --rawaud-samplerate 8000 my_pcm_alaw.data
but it seem it can't work correctly. Which parameters of VLC can be used to specify the audio data codec?

please give your advice.
