mmm, sorry to sound a bit trivial but ... did you check your mixer levels ? sometimes, ALSA resets all levels for reasons only known to itself ...

James is right. Try the mixer first.
If it's not the mixer, the thing this most reminds me of is the reason why I
finally abandoned the previous LTS. I ran it for about a year, and then ALSA
broke quite catastrophically. The structure in /dev wasn't getting created
properly at boot, and I went so far as to manually mknod the missing
character special files, to no avail. I suspected hardware troubles, which
happens to be how I wound up with three soundcards in this computer.
Ultimately, it was an unsolved mystery. I have no idea what broke how or
why, and I don't even have any halfway credible theories.
Formatting the system partitions and installing from scratch solved it though.
Hopefully you won't have to resort to all that.
