When I click kmix, I see two sound devices.
One is my graphics card, the other one is the onboard sound chip.
Everytime after a reboot the volume of the vidcard ( I do not use the sound ) the volume is at 100%.
I disable it every time but after a reboot its back at 100%.
How do I change this permanently ?
I do no want it to be at 100%.
I am worried it might be bad for the hardware ?
If you don’t use it, I doubt it matters, but you can just set the sound profile to off for any sound device you do not use. Take a look at my blog on the subject and my links for music videos there as well: PulseAudio and Selecting the Proper Sound Card Configuration - Blogs - openSUSE Forums
Thank You,
Thank you that did the trick.
Great blog. 
Very happy to help. Did you check out any of the music videos? Do you have a good one from YouTube you would add?
Thank You,
