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

[Julian Edwards]

Hi folks

I first installed Myth about 2 months ago and followed Jarod's excellent
guide.  I successfully had the SPDIF output on my Audigy2 working from
mplayer, Ogle and OSS emulation from Myth so that everything went
through the digital output.

However, I did a dist-upgrade the other day (which upgraded the kernel
and alsa) and I've now lost the output from everything. Mplayer (using
-ao alsa9:spdif -ac hwac3,) says that it can't open the sound device,
and Myth fails silently.

This is the mplayer output:
---
Checking audio filter chain for 48000Hz/2ch/16bit -> 48000Hz/2ch/8bit...
AF_pre: af format: 2 bps, 2 ch, 48000 hz, big endian AC3
AF_pre: 48000Hz 2ch AC3
Could not open/initialize audio device -> no sound.
Audio: no sound
Starting playback...
---

Bizarrely, the command "aplay -Dspdif <wav file>" works fine (which
alleviates my fears that it was a hardware failure).

Here's the versions I've got now:
alsa-utils-1.0.4-7.rhfc1.at
alsa-kmdl-2.4.22-1.2179.nptl_47.rhfc1.at-1.0.4-22.rhfc1.at
gnome-alsamixer-0.9.6-2.fr
alsa-lib-1.0.4-12.rhfc1.at
alsa-driver-1.0.4-22.rhfc1.at

Thanks for any help.
J.
