[gentoo-user] /dev/dsp: Device or resource busy

[Alex Schuster]

Hi there!

I want to play Quake3. games-fps/quake3 works, but somehow extra stuff
(maps, models) I downloaded and put into /opt/quake3/baseq3 is not being
used. I think I had such problems before, so I used to run
games-fps/quake3-bin instead. I have no sound. 


There are error messages:

/dev/dsp: Device or resource busy
Could not open /dev/dsp

This is true, even as root I cannot echo something to this device. lsof
and fuser return nothing, so I wonder what is using the device.

I had sound problems with Quake3 in the past, and found a wrapper script
quake3-sdl-sound [*], that worked. But now it doesn't.

Any ideas? There will be a big match going on with my little sister this
evening, so you see this is a really really important issue!

Hi Alex,

try (as root)

    fuser /dev/dsp

to figure out, which task helds that device...

Typically, IME, Flash.

It should be possible to launch the binary using a wrapper that
redirects things to either ALSA or PulseAudio. I don't remember,
exactly; it's been a long time since I've had to deal with OSS-only
apps.

I just found a workaround: It seems games-fps/quake3 looks for stuff
in /usr/share/games/quake3 only. I made this a symlink to /opt/quake3,
and now all the custom maps and models are found. But still I would like 
t know how to make such applications work again.

I get no output at all.

The access rights to that device are ok...?

Yes, read-write access for all in the audio group:

wonko@weird ~ $ ls -l /dev/dsp 
crw-rw----+ 1 root audio 14, 3 Feb 18 07:23 /dev/dsp

And otherwise I would expect a permission denied error.

Maybe it works when I log out of KDE and have a minimal environment, but
I cannot do this now, too much important stuff is running at the moment.

I didnt know the origin of the error message "resource busy"...so if
it had come out of the application...even an error message can e wrong
;)

May be it would help to unload the sound related modules from the
kernel and modprobe -a them again?

Should have the same effect as the reboot without a global hickup of
the whole system...

just a shot in the dark...

fingers crossed!
