Hi, As you might know, I'm trying to make life a little bit easier for laptops with a built-in subwoofer. Part of that is to revisit our "enable-lfe-remixing" setting, which is currently disabled by default. This means that people playing back stereo material, will, by default, complain that their speakers sound more tinny than on Windows. 1. I understand that there might be reasons we have it disabled by default, but it would be good to have those reasons lined up. What are those reasons really? 2. Should enable-lfe-remixing be a global setting? Or should it be configured per port? Per profile? 3. Should it happen that I will end up having to write a low/hipass filter for properly separating LFE from main speaker frequencies, what are your recommendations? I don't think we have a module we can use, but are there finished implementations in libraries that we can just try to import into PA? Or do we need to start over from scratch? Has anybody (e g Alexander) done any research on this topic? -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic
