Right, so I am so sorry about misleading you. It turns out that I could reproduce the issue even on Windows. I just had to try that harder than I thought. Before checking whether I could get a cooler, do you think it would be worthwhile changing the BIOS firmware and/or cleaning up the dust internally after disassemblying it carefully? Thank you for all your help. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
