gnome-alsamixer crashed with SIGSEGV in g_closure_invoke()

StacktraceTop:gam_mixer_show_props_dialog (gam_mixer=0x0) at gam-mixer.c:596
g_closure_invoke ()
?? () from /usr/lib/libgobject-2.0.so.0
g_signal_emit_valist ()
g_signal_emit () from /usr/lib/libgobject-2.0.so.0

could the users having the issues give details on what they are doing to get the crash. is alsamixer listing any soundcard?

my sound card just disappear when i rebooted. now i get dummy output..... and no sound.

also i wasn't able to send the sound out through the phone jack i have hda audio, in 9.10 the sound was getting out through virtual 5.1,
in the line in jack. with lots of noise...

when there is no sound card detected by pulseaudio server and PA server load "Dummy Output" module

aplay -l
aplay : device_list :235 no soundcards found...

application can still use the "pcm" device of pulse with "Dummy Output" module but "ctl" device of pulse seem disappear

alsamixer
cannot open mixer : no such file or directory

gnome-alsamixer
(gnome-alsamixer:1335) GLib-Object-CRITICAL **: gtype_instance_get_private : assertion failure ' Instance != NULL && instance->g_class != NULL' failed

The above situation can be reproduced by virutalbox with sb16 in Maverick , since the "virtual sb16" cannot be autoloaded because of isapnp , the PA server cannot detect any sound card and use "Dummy Output"

after manual load by "sudo modprobe snd-sb16 isapnp=0"

alsamixer and gnome-alsamixer work fine after restart of PA server by logout/login

This mean that PA should also provide ctl.pulse for those mixer application such as gnome-alsamixer when there is no sound card detected

there has been no duplicate for over a year, is that still an issue for anybody in recent ubuntu version?

Not at all. Thanks.

Sorry, but i have changed my OS 6 month ago, i am using
now Debian squeeze, and it is difficult for me to give you more feedback
about this tools.

Best regards
