No audio from SMPlayer

[sindi]

I thought smplayer only worked with mplayer.

Do you mean to try a different player with smtube, such as vlc or xine?

Mplayer itself is usable (for 360p or 480p mp4), it is smplayer that loses sound (on the 8100 with maestro 3i sound, but not on T23 with i810 sound)
