Don't know much about SPDIF, but my guess would be that your sound
card settings have got trashed in the upgrade. You need to use
alsamixer to get the settings right as per Jarod's guide. If you have
a BT8x8 card then you usually have to configure the line-in so that it
records the sound. Or maybe your sound-out/PCM settings are on mute. I
have an intel on-board sound card with  screenshots of the settings
which I'll send you separately. Remember that I don't have SPDIF,
though.
