Hm.  Does alsamixer show that guilty control?

I ran strace on alsactl and it consults a very small number of files
while doing a 'store' operation, so there are very few places that
Mic Capture control could be hiding.  You might try using strace to
see what turns up. (If the error bothers you, of course.)
