Hi, This is regarding some trouble I am having with my Realtek sound card. I have a Realtek 5.1 compatible soundcard in-built on my Intel DG31PR motherboard. Driver Version is 220.127.116.1136. Codec is ALC888 (screen shot of info box is attached) The problem: I am not receiving any audio output. My layman's assessment of things is that some sort of output jack on my front panel is being detected when there isn't any which is blocking\over-riding the back panel output (just my observation on possible cause). The Realtek Audio manager seems to indicate that there is some sort of jack is plugged in to the front panel. Just to clarify - no pop up or anything came, I just started checking the manager when i stopped getting output. (screen shot attached.) To assist your analysis, these are things that I have checked \ tried: Things I have checked: That speakers (creative 2.1 sbs a300) are powered on. That speakers are working (tried it with another device). That the audio device is default and enabled. Device manager does not indicate any driver /conflict issues. That speaker volume, system volume (both master and individual) and music player volume (have tried various applications/games, etc) are not on mute. Things that I have tried: Have tried disabling enabling drivers. Have tried uninstalling and re-installing drivers. Have unplugged cable to front panel - no change. put it back in - no change. Tried plugging in speakers to front panel. no output. continues to indicate front panel out Tried 4CH output with front panel as one output and back panel as the other output. Also: No audio codecs\dx upgrade etc. were installed immediately prior to the sound not working. Looking forward for your advice on what to do next.
