BleepingComputer.com: New Case No Sound

Hi all im in need of help i have just changed cases on my comp and for some reason lost all sound i mean i get nothing i have checked all volume and mute controls and they are ok i have checked speakers and they are ok i have also bought a new sound card and put that in but still nothing i have tried headphones and get nothing from them either the only thing i can think left is the up dating the bios but im not sure if this is any thing to do with audio is there any thing else i have missed?pls pls help

Where are you plugging in the speakers? If you are plugging them into the front of the case, then perhaps you missed hooking up the audio leads to your motherboard.

i havent connected the front panel audio as they are a dif plug to the mobo. I am plugging in to the rear in the correct coloured socket i tried again last night to install a new sound card and couldnt even get the comp to start so i think may be some thing is clashing but what i dont because i have installed nothing new at all and it used to work fine before changing cases, i think i have prob damaged mobo connection when swapping over cases which i a shame coz thats gonna be expensive to replace just for audio.

Do you see any problems in device manager, IE red X's or question marks?

If you go into the sound control panel, does it list something as its default playback device?

nope no x's in device manager either i am thinking that the connector on the mother board is knackered but not got a clue as to why it wont let me install another sound card could poss be drivers or codecs clashing with each other?

Yeah that sounds like a mobo problem to me. Have you checked that it is properly raised off the bottom of the case? You may have a short somewhere.

yup i have checked that im beginning to think im cursed with mobo's as this is the third 1 in about 15 months first 1 got a drink all over it curtesy of the wife, second one decided it just didnt want to live any more and now this one haha.

Seems like the computer gods have frowned upon you. . .

well when u tinker with things you dont truely understand only bad things can happen lol.
as i built this comp my self and it works quite well (most of the time) hehe.
oh well its an excuse to upgrade the mobo any way i got a asus sli premium at the mo think i will go for a deluxe version now having a 939 cpu its getting pretty limted for choice now.
and i want to thank all for the help and advice given with my problem this is a very helpfull friendly site thx people

Ok i have fitted a new mobo and still have the same problem absolutley no sound at all i have realtec alc850 audio installed and its not detecting any tjing i plug into the jacks at the back put old mobo back in and its the same their also have tried dif speakers still no joy im getting desperate now can any 1 give me any clue as to whats happening here pls?

Can you please give us excact type of Mobo and further setup? If you go to CONTROL PANEL and than SOUND is there anything you see? If you click the taskbar bottom left you see a little speaker there. If you double click that is there a box clicked mute all? I'm shooting here of the top of my head here.

it turned out to be a mobo problem after all even with second board a little bit down to my self though tbh gone to far with the over clocking despite the fact it worked for a whilr it turns out some parts where running faster than others and just could'nt communicate with each other got it all sorted now though. smiles all round . i have got a amd athlon dual core 3800+ running at 2.7ghz at the mo its good enough for me with a asus k8n sli deluxe mobo and 2 7900gt cards also slightly over clocked hehe it will do for me for now, well at least untill i get my next opteron cpu and start breakin that baby in lol or may be breakin something else lol thx all for help and ideas on whatn the problem could have been most app
