Gentoo Sound Problem

[mystified]

I just got thru reinstalling gentoo. I've had no problems with sound in the past. But this time when trying to use mplayer I got the following message:

 

Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (Device or resource busy)
The sound server will continue, using the null output device.Sound server informational message:
Error while initializing the sound driver:
device /dev/dsp can't be opened (Device or resource busy)
The sound server will continue, using the null output device.

 

I tested sound in the kcontrol center and it works fine. Any suggestions?

alsa? oss? If alsa is it running?

mysti..........

 

if you haven't got this worked out yet, you might wanna try lsof to see what is using that device & giving you the busy error. it works in MDK, but it's a generic Linux tool, so i'm guessuing it will work in Gentoo. maybe....... :unsure:

 

in terminal, as root, do the following..........

 

lsof -V /dev/dsp

 

if you get a "command not found" error, then you must first install lsof. in MDK you'd urpmi lsof, so just install it by whatever means you use in Gentoo & try the command again. once you know what's using the device, i'm sure you can take it from there.

Yes it's alsa sound and it has been started bvc.

 

Sorry, chrisz, I tried what you said and there was no device using the sound card.

[jlc]

ls /dev/ | grep dsp

 

ls -la /dev/dsp

 

ls -la /dev/sound

 

ls -la /dev/snd

 

ps -ef | grep artsdsp

 

ps -ef | grep esd

 

What do you have for all those?

 

Might also try starting mplayer with

 

mplayer -ao:/dev/dsp <----- I think that is correct, depends what is there.

Well something I did got the sound working. My only problem now is there's no gui for mplayer so I can't turn up the volume.

[jlc]

emerge -pv kmplayer

 

kde frontend to mplayer

 

Since you like kde so much :D

Thanks!

 

I'm getting a strange error message at boot tho. /etc/asound.state unmute card?

[bvc]

alsa-utils installed?

[mystified]

yes it is bvc. Fortunately the problem was solved easily by restarting alsa sound.

Maybe -

#USE="alsa" emerge mplayer

 

check your /etc/mplayer.conf

 

This is for the plugin but:

http://mplayerplug-in.sourceforge.net/howto.html

 

From the above link -

mplayer configuration

If you are using GNOME as your desktop environment add this line to $HOME/.mplayer/config:

ao=esd

 

For KDE add:

ao=arts

 

Also try

 

#emerge kplayer

 

another nice gui mplayer front. :D
