I’m having sound problems my K3S. I don’t recall this ever happening with my K3 but when I launch windows 7 on my PC, the K3S, USB Audio CODEC is turned off. It’s shown in the Volume Mixer and when I double click on the Icon, it launches the properties for the CODEC. I can click on the Levels tab and set the Microphone level. When I click on the speaker Icon, the sound is on and I can adjust the level.
Here’s what gets weird. After the few or even several seconds, the sound goes off and the speaker icon shows the circle with a slash. The microphone level also moves to zero. I have the volume mixer stretched halfway across the bottom of the monitor and I noticed that other sound devices are shown. At least 3 or 4 pop up and they all have level controls and a speaker icon. If I move a slider up, it pops back down. If I click on the speaker Icon nothing happens. For some reason the they hijacked all of the legitimate record devices and turned them off.
Now this is really weird. If I launch Task Manager, for a few seconds under the processes tab, I can see several copies Regsvr32.exe, then they disappear. I can go back the K3S CODEC and turn it back on.
Everything is OK but after a few or even several minutes the Regsvr32.exe processes are back and the sound goes off. Several copies of the bogus audio devices are back and if I kill Task Manager and launch it again, Regsvr32.exe and the bogus sound devices are gone, for several minutes and the process repeats.
I normally run Norton Internet security and do scans periodically but I never had a virus. My son came over and he ran Malware-bytes and several other virus detection programs but nothing was found.
Has anyone had this problem? Notice in the Volume Mixer that there are several copies of Microsoft(C) Register Server. They disappear when I launch Task Manager. I can turn on the audio in the K3S in the Properties by clicking on the speaker Icon and adjust the Microphone level. Several minutes later the bogus audio devices reappear. As I was writing this thread, I now have six instances running in the Volume Mixer.
