Running volti-mixer results in the following stacktrace:

I guess the problem is with the "ThinkPadEC" which is ThinkPad console audio 
control (not a real soundcard).

Just upgraded to 2.6.36 and installed volti. I did't notice ThinkPadEC with 
2.6.34

Hi, as it looks right now I can't do much. If alsaaudio can't open thinkpad 
control I can only try to disable/hide it. I had problems with this on my old 
thinkpad, but it didn't worked in alsamixer too so I disabled it in kernel. I 
will see what I can do about this. Thanks for reporting.

Can you try again with latest svn, I just commited fix that should handle this 
better. Thanks.

Now it works, thanks. Another problem I've noticed: something is wrong with 
mixer channel indexing/ordering (screenshot attached):

I deselect all IEC958 channels, but one is still present on the panel while 
Capture channel disappears.

I have a similar problem on my Thinkpad X301:  switches like IEC958 are shown, 
but toggling the checkbox makes one of the mic channels disappear; other mic 
channels are similarly garbled.

This is a lower priority for me since there's always alsamixer, which functions 
correctly.

Yes, I am aware of that, mixer needs more work. I was thinking of filtering and 
grouping all switches in separate tab, but I need to check first if I can do 
that by only checking mixer.volumecap().
