no sound after recent Lucid upgrade

[Jamie Strandboge]

After not upgrading my Lucid box for several days, I upgraded today, rebooted and had no sound. Alsa seems pretty unhappy in general:

$ sudo aplay -l

Please update fully and reset status to New if reproducible. (See also bug 523716, which is certainly causing your aplay and alsamixer symptoms.)

Yes, we discussed this in #ubuntu-devel. I now have 1:0.9.22~0.9.21+stable-queue-32-g8478-0ubuntu8 for pulse and 1.0.22-0ubuntu5 for libasound2-plugins. I get the exact same error messages as before even though libasound2-plugins does ship the pulse libs now:

$ dpkg -L libasound2-plugins | grep pulse
/usr/lib/alsa-lib/libasound_module_conf_pulse.so
/usr/lib/alsa-lib/libasound_module_ctl_pulse.so

Setting to Confirmed because I'm seeing this issue too

Same issue here, but sound works no problems, just a little quiet, can't seem to set it louder like I had in 9.10

It works tho :)

Would you provide strace and ltrace output, please?
