'modprobe thinkpad_acpi enable=0' command issued on a terminal after SL510 laptop booted (and thinkpad_acpi module was loaded) does not fix the mute button issue.
2 additional pieces of info: - whenever the mute button is pressed with or without the thinkpad_acpi module loaded, I got the following event in Klog: [184824.193753] hda-intel: spurious response 0x0:0x0, last cmd=0x23900f - without the thinkpad_acpi module loaded, the mute button is effective for the internal speakers ONLY, but is ineffective for the audio external jack: the external speakers keep on outputting the sound. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/595896 Title: Thinkpad SL510 Mute button not working -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
