Needed help to get sound working via SPDIF TosLink - solved see below

System:
 Installed # LinuxMCE-DVD-i386-rc2.iso

Motherboard Asus M2N-SLI Deluxe Green nVIDIA Socket Am2 ATX
Processor AMD Athlon 64 X2 Dual-Core 6000+ 3.0 GHz
Memory 8096MB Dual Channel 4096MB PC6400 DDR2 800MHz Memory
Video Card -  GIGABYTE GV-NX85T256H GeForce 8500GT 256MB 128-bit GDDR2 PCI Express x16 
Hard Drive  - HITACHI Deskstar 7K1000 HDS721010KLA330 (0A34915) 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s
DVD - SAMSUNG SH203N SATA
HD-5500 Hi Definition Television PCI Card – pchdtv

Having problems with sound – in AV Wizard got no sound on step 6, did get sound on Dolby and DTS - later found that in step 6 sound has to be cranked up to 100% to hear it.

following instructions on the wiki got tv working both cable analog and some digital channels:
http://wiki.linuxmce.org/index.php/PcHDTV_HD5500

but no sound for TV -
added cx88-dvb and cx88-alsa to /etc/modules file
(not sure if this was needed but saw some advice on this forum calling for it)

In MythTV Front End (KDE Desktop > Multimedia > Myth Frontend)
Utilities Setup > General
set Audio Output Device to ALSA:default
set Passtyhru output Device to ALSA:iec958:{AESO oxo2}
check enable AC3 to SPDIF passthru
check enable DTS to SPDIF passthru

In terminal window open alsamixer
unmute the iec958 device.

The above got sound working for MythTV - posting info here in case it is helpful to others.

However, I still get no sound from DVDs and recorded TV material. 
Anyone know what further tweaks are needed to get sound on LinuxMCE Video playback?
Bill
