Thank you. My guess would be that something else is using the sound without letting mplayer share it. You could try: lsof | grep snd to find out which applications are using it. An example from my own system: pulseaudi 4506 jk 26u CHR 116,6 0t0 3219 /dev/snd/pcmC0D0p This indicates pulseaudio is using the sound. > > 2. What is the function of the option "normalize sound" in > gmplayer/mplayer? I am just curious about it.. It's probably tied to -af volnorm, which tries to make all files sound equally loud. It looks at the volume over a short period and adjusts it. _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
