Our tech help drifted away over the last few months and now it's left entirely to me to sort out I realise that I don't really have a clue

We had to rewire everything following a power failure and I think I've made a serious mistake - I can't get any sound in Windows or Myriad. As I'm going 'blind' it's a bit of a struggle and our Bronze Support package has run out... wondering if anyone here can help?

We're using a Delta 10/10 and a Soundcraft Spirit ES, with Myriad supposed to be going into the first 4 stereo channels.

Thanks,
