[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?
