[linux-audio-user] NO line in signal

Hi OK the studio machine is now fully on the net after laying cat6 cable about etc. I did an update upgrade and an alsaconf just to get the basics on the way. The previous problems of alsa not starting were gone. this may have been the above process but it might also have been an IRQ problem. I pulled the sound card (sb) out noticed on reboot IRQs had reaaranged themselves. Anyway i now have one small problem, which I have had once b4 and I fixed with a complete reintsall. I dont particularily want to go there again. Everything works except any audio present on the line input. I checked the signal from my mixer and also noticed that it was coming into the card and being passed on to the cards output. But no matter what i did I could not get it into ardour etc. I even hooked up jack.scope to the capture inputs with no luck. I checked the alsamixergui levels and settings and capture..all correct. I was able to patch hydrogen output to ardour and scope etc. Its as if the line input is just not getting thru. Any ideas
