[mythtv-users] MythMusic - CD Playback - Not working

Hello,

I run Mythbuntu 7.10 with Mythtv 0.21. I am having difficulty with what 
I think is an ALSA/Mythtv audio set-up problem.

I have Myth set-up and working perfectly for TV, MP3 Music, MPlayer 
Playback (SPDIF pass through working for everything)

When I go into Media Library>Listen to Music>Edit Playlist and select my 
CD that is in the CD drive. I see the songs on the CD are all listed in 
the playlist (cddb lookup worked), with the first highlighted yellow. 
But I don't hear any sound and the CD drive isn't spinning.

I can play the CD perfectly from VLC though!

This is driving me nuts as the Wife Approval Factor is dropping (she 
wants to be able to drop a disk in and have mythtv "just play it").

I have tried many combinations of audio settings in set-up > General 
some give me results that work in Mplayer,  DVD and TV etc, but not in 
the "playback from CD" area.

I am running a pretty basic Setup > General audio setup

Audio output device:     /dev/dsp
Passthrough Output Device:    default
Enable AC3 to SPDIF passthrough: Checked
Enable DTS to SPDIF passthrough: Checked
Aggressive sound card buffering: Off
Use Internal Volume Controls: Off

I have an .asoundrc that looks like this.

pcm.!default {
        type plug
        slave {
                rate 48000
                pcm "spdif"
        }
}

Any tips? I suspect I have a sound configuration that requires further 
tuning, I just need a bump in the right direction......

Any help appreciated.
