I just did a clean install of Leap 15 on a new partition. Installation went okay but on the first boot, after grub, I get a sound that syncs with the splash screen animation. I rebooted and edited the splash entry from splash=silent to splash=verbose. The sound is still there even though the animation screen is not displayed. Worst yet is that the sound continues even after I have logged into the system.
What is going on?
Never seen or heard of that before. You need to tell us about your hardware. Particularly what sound card/chip lspci should show the hardware .
The machine is an HP DC5750 Microtower. If I run lspci it shows as AMD/ATI SBx00 Azalia (Intel HDA) Yast sound says the driver snd-ada-intel. It stops while I am playing a sound through the speakers, then starts again shortly after the sound stops playing. I can stop it by deleting it in Yast sound.
If I reboot to Leap 42.3 it works fine as it has for all previous releases.
