[mythtv-users] Lost SPDIF output after apt-get dist-upgrade

And here I was thinking I had gone crazy.  I noticed the same thing when I 
did an apt-get upgrade on Saturday.  I had gone from the 2174 kernel (with 
associated alsa) to the 2179 kernel.  I am using the built in optical on 
an Abit motherboard using one of the Intel 845 chipsets (forget which one, 
but I enable IEC958 in gnome-alsamixer and had optical output).

I haven't had a chance to troubleshoot fully (I'll try aplay tonight when 
I get home), but I lost the optical output in mplayer and myth.  I am 
running the same versions you are.

Anyone else notice this or have a fix for it?
