hi,
I have recently upgraded my X version from 4.2 to 4.3 and for some reason my sound does not work with mplayer.It used to work just fine before.It still works fine with gaim and xmms etc. but there is no sound in mplayer.the error message i get is:

I can see the video but no sound.
I am running kernel version 2.4.24 on a debian sid machine.
i run mplayer with the following parameters:
mplayer -vo xv [filename]
i have tried this with .mpg,.avi,.asf and also with .mp3 and all give the same error.
i am running mplayer version

Code:

mplayer-686 1.0-pre3-0.2 The Ultimate Movie Player For Linux

i dont know what could have coused this but if someone could help me...i would really appreciate it.
thanks

"alsa-init: no soundcards found: Success"

Are you using ALSA output in XMMS, or the standard OSS? It looks like ALSA's not setup with your soundcard. Try changing your audio output plugin using "mplayer -ao oss". You can get a list of all sound systems MPlayer is compiled with by running "mplayer -ao help".

well apparently using mplayer -ao oss made things right.
i have not even touched alsa since i installed debian....and since it does not come statndard in 2.4.x kernels i am sure i am not running alsa for my sound.:

Code:

mpegpes DVB audio output

        oss    OSS/ioctl audio output

        alsa9  ALSA-0.9.x audio output

        arts    aRts audio output

        esd    EsounD audio output

        nas    NAS audio output

        sdl    SDLlib audio output

        null    Null audio output

        pcm    RAW PCM/WAVE file writer audio output

        plugin  Plugin audio output

this is the output from mplayer -ao help
anyways do you have any idea what might have gone wrong here.Sound was working just fine before i upgraded X.
thanks.

No idea, sorry. Sometimes it's better not to ask, and just be glad it works ;-) (Okay, that's never really true, but I'm clueless nonetheless).

I had a similar problem. When I upgraded X from 4.3.1 to 4.4.0 (ducks flying objects) mplayer switched it's default output plugin to null, rather than alsa.

what is the difference between 4.3 and 4.4?and did you find any debian sources for 4.4?thanks

Well, there are a few differences. The main one that's caused dispute is that the license is not compatible with the GPL, although it's still open source software. For me, the best difference was that the Mesa code has now been linked in with DRM for SiS graphics cards. Although it now locks up, at least it says I have direct rendering/
