For me, the problem is solved as I found the right parameter to give to mplayer/mencoder (using alsa device), thanks to a french documentation website contrib.
I use now :
$ mplayer [...] :forceaudio:alsa:adevice=hw.2,0: [...]
instead of :
$ mplayer [...] :forceaudio:adevice=/dev/dsp2: [...]
Of course, not resolve problems for other software using only OSS ...
