alsamixer opening problem

[dontiego]

Hi all!

Going slowly towards a working sound here. Only slowly.

alsamixer was working fine, but all of a sudden it stopped working.
$ alsamixer
ALSA lib control.c:874:(snd_ctl_open_conf) Cannot open shared library /usr/lib/alsa-lib/libasound_module_ctl_pulse.so

alsamixer: function snd_ctl_open failed for default: No such file or directory


However, this seems to be working:
@ubuntu:~$ aplay -l

$ alsamixer -c 0

I wonder why "alsamixer" alone wouldn't work?

In System->Preferences->Sound->Devices I set everything as PulseAudio Sound Server (it wouldn't work when I put ALSA).

Running alsamixer seems to miss some kind of pulseaudio related stuff, but how could I fix it?

alsamixer -c 0

Is that a bug?

Yup sounds like he just found one..alsamixer through pulse should just show the volume level if the default mixer is set to pulse. Could be a reporting error from the card driver. This is a good one to send to the alsa devs. Sounds like the sb emu1010 driver borks with oss and pulse.
If he is reading alsamixer -c 0 with the actual card and not the gnome pulse melange of Ubuntu then it is most likely not an Ubuntu issue.
