So in the long run, I think it would be better to leave all auto-muting to userspace. Then stuff like pulseaudio could to advanced decision of how to handle input events. But that's the long way. There are certainly ways to disable auto-muting for Realtek ALC888, look along the lines of "speaker_automute" and "unsol_event". It is also possible that you could tweak your user_pin_config to trick your HP out into a Line Out. That way it won't automute, and you don't have to recompile your kernel. As a side note: The VIA HDA driver, I believe, have an option for turning automute off. But it also sets "mute" on a misnamed control at the same time, tricking PA into believing that you want to mute all output. So PA is "helpful" and mutes everything else as well. :-/ -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
