Hello everyone, I came across this forum while researching my problem and I noticed that there are drivers for this card on this forum so maybe someone can help me. Basically, I bought this card from E-bay recently. I bought it because although my graphics card can do audio over HDMI, it can't do things like ALchemy, which I like to use with my retro PC games. I installed the card and at first everything seemed great, I even left the seller good feedback :uhoh: but then the problems started. I was editing some videos for my website and the audio started having tiny clicks and scratches on it. Thinking something was wrong with my mic I rewound the video but the clicks/scratches were not in the same places. I played an MP3 and it was the same thing. Then I came here and tried the new drivers but still the same problem. It affects HDMI and Analogue audio the same. I tried playing a few hours of Left4Dead 2 and the problem was there too, spoiling the otherwise lovely sound. Here are my system specs:- OS Name Microsoft Windows 8 Pro Version 6.2.9200 Build 9200 System Name W8-GAMES System Manufacturer Gigabyte Technology Co., Ltd.
