Please send an alsactl save file with the offending configuration
Attached.
I saved this file when the audio was working (i.e having turned the 
offending control on with alsamixer) but restoring it stops it working.

I'll try to reproduce (though possibly not before Monday).

Thanks.

Could you please also expand on "audio stops working" - for example, do
you get any diagnostics in dmesg, do applications appear to think they
are running normally, is there any noise at all (eg, static) and do any
other audio paths work?
No unusual dmesg output, the apps think nothing is wrong.
It seems that just the offending control (or the actual DACL/R -> SPKMIX 
mixer channel) stops working. I can still get audio through the 
headphones, still can get clicks when turning everything else on and 
off. I can even get audio on the speaker by the alternate routes: DACL 
-> HPMIXL -> SPKL and DACR -> HPMIXR -> INV2 -> OUT4.
Routing SPKMIX to the headphones gives no output on the headphones.
