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.

Thanks.

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.
