[Vorbis-dev] Can you provide me some information on music players using ogg.

[Diptopal Basu]

Hi Conrad ,

  Let me check ,  I am not too sure if ALSA/OSS is configured as I
downloaded the Linux source and compiled  it myself for the Versatile
baseboard , I will try to do as you advised . So I assume for Ogg123 to work
, the og and vorbis libraries should be present ?
