RE: [suse-linux-e] Hardware activity causes speaker noise
Rafael, Have you adjusted all the volume levels for the inputs? I've noticed OSS defaults the MIC and LINE-IN inputs to about 2/3 maximum volume. The noise could be picked up by these inputs. Once the volumes are adjusted with a mixer, use savemixer in the OSS directory to make these the defaults when OSS starts. cott worley Compaq Portables scott.worley@compaq.com -----Original Message----- From: Rafael E.

I get noise from the speakers when I type, move the mouse and access the hard drive. This occur even if I turn off the sound drivers. Does anybody have any clues about this? I don't get these noises when I boot the win98 partition.

Adjusting the MIC and LINE-IN levels did not change the noise at all. However, I significantly reduced it by changing the output setting of my sound card. I have a ESS 1689 based PNP card. The ouput has two possible settings, Speaker Out and Line Out. The first one is amplified (for use with passive amplifiers) and the other is not. I switched the output to Line Out and I just get a very low hum when I move the mouse. The keyboard and disk access noise are gone. Hope this helps somebody. -- Rafael Herrera Laboratory for Computational Neuroscience University of Pittsburgh http://www.neuronet.pitt.edu/~raffo
