No sound in mplayer and mplayer-plugin

[Sjoerd Hiemstra <shiems146@kpnplanet.nl>]

Hi,

I've got mplayer and mplayer-plugin for mozilla from Marillat's site
installed in Sarge, as well as w32codecs.

Video displays fine, but no sound is audible.
Sound is OK in other apps, such as XMMS and RealPlayer, though.

These are the error messages from mplayer:

    alsa-init: no soundcards found: Success
    Could not open/initialize audio device -> no sound.
    Audio: no sound

Any idea what could be done about it?

S.H.
