Thanks for fixing or updating? (see bug #1448493)

We've discussed this a bit on IRC, but for the bug report as well:

I was not able to trigger a crash when running `volumeicon` on my 15.04 vm. One theory is that it might be related to Nvidia since that is mentioned in the error message.

From the discussion with penguin42 on irc too:
 volumeicon-alsa-dbgsym is now installed and here is the new output:
 http://paste.ubuntu.com/11867686/

then as per Penguin42's instructions, got alsa-info.sh:

$ chmod a+x alsa-info.sh && ./alsa-info.sh

then:

My problem was that on my newer notebook 'HDA Intel PCH' sound card was not the default for some reason. It's either different hardware or could also be the fact that I'm using 15.10 instead of 14.04

You may try to change the 'card' parameter in the .config/volumeicon/volumeicon. It is set to 'default' by default. Changing it to 'card=hw:1' solved the problem here.

card=hw:1
