I recently decided to buy kaspersky total security, when i finally installed and created an account i started a full scan and when it was finished i restarted my PC. After my restart i had no sound, it showed “no audio output device is installed”. After 1 hour trying to figure out the problem i finally found it. I had to configure audio stream protection, so when i finally allowed my realtek audio and my Xonar essence STX Audio Center my audio was back. 1.5 hour in and i was finally done.. except for one thing. Xonar essence STX Audio Center could not find my external sound card. My experience of kaspersky is really bad and my evening is ruined, and on top of that i missed greece-sweden. Im actually really mad and dont know how to solve this. Just uninstalled kaspersky total security and it still cant find my external sound card…..
