https://bugs.freedesktop.org/show_bug.cgi?id=75985 --- Comment #26 from Maik Freudenberg --- Created attachment 136416 --> https://bugs.freedesktop.org/attachment.cgi?id=136416&action=edit Kernel module to toggle audio function Thank you, Daniel. I was too blind to see the attachment. Attaching some c/p work using/abusing bbswitch as a framework and your enable code. So works like that. Creates a handle /proc/acpi/nvhda which takes ON and OFF. Since my hardware doesn't have outputs I can't test it farther than turning on and off. Can be loaded and used while the proprietary driver is loaded to be used for further investigations. - Does the prop. driver react to this immediately, i.e. make audio work? - If not, does plugging out/in the hdmi cable make it work? - Are any pci config space changes noticeable? -- You are receiving this mail because: You are the assignee for the bug.
