I've just built my HCPC and I'm still only using the onboard sound on my asus A7N8X ( can't decide what soundcard to get ) What's bothering me is that when I switch off the PC I get a loud pop out of my speakers and my sub ... which ain't doing them any good. I'm using the line out from my motherboard straight into a ROTEL 1075 5 channel power amp driving Monitor Audio speakers and also a REL Strata. I know I could switch the amp and sub off first but I was hoping to have the whole system automated using the 12 volt trigger on the ROTEL enabling me to tuck the amp and sub out of site ...... more wife friendly. Has anybody come across this problem before? And, is it likely to be the same problem with a good quality soundcard? Any suggestions would be greatly appreciated. Also what's the best soundcard for home cinema?
