Thanks for posting bud, I'd already tried your solution earlier.
In alsamixer, panning across to the far right I don't have an external.
From left to right:-
Master, Headphone, PCM, Front, Front Mi, Front Mi, CD, Mic, Mic Boost, S/PDIF, S/PDIF D, S/PDIF P, Beep & Mono.
My problem is I dont have speakers as an option as a connector output just headphones, which work great.
That's why I know the sound card has been detected successfully just for some reason speaker output cannot be generated.
Thanks again for taking the time to reply and suggest a solution.
