Thanks for your reply. When I installed Mythtv a user was created- 'mythtv'. I assume this is the context under which it runs( how can I be sure?) althoughI start the backend as root from a command line and start the front end as myself from a command line. Anyway, following your suggestion, logged in as root, mythtv and myself I can get sound playing mp3's mpegs wavs etc using various programs(except myth). I'm guessing that this should be the case
What might point me in the right direction is if someone with a similar setup as mine could post a working configuration. ie. what ALSA/OSS components were compiled or included as modules in the kernel. what mixer levels were set, and what needs to be filled in in mythforntend for sound device and mixer.
I know I'm just missing something, but I can't figure out what it is
I also read somewhere that I might require a .asoundrc file. What is this, where does it go and where can I get one?

I have tried capturing on all the inputs, yet I get no sound. looking back through the archives this seems to be a common problem but unfortunately not many people seem to post their solutions. I'm a bit of newbie with linux and perhaps bit off more than I can chew attempting to set up mythtv 0.19 as one of my first projects. If someone could provide me with *detailed* trouble shooting steps I'd be very appreciative. I'm running debian with a 2.6.15 kernel. My sound card is an onboard Nvidia nforce2

what user does mythtv run as? Does */that user/* have the ability to
output sound? (su - to that user then try running some movies and see if
it outputs sound).
