Comment 79 for bug 994685

It should be fine upstream, since the newer auto config code copes with the machine well, just 3.2 and I think 3.3 kernels will experience issues (the newer kernels than this have the commit Joseph had backported earlier and chooses a configuration which allows for an independent headphone volume slider, so it's fine), so yes, it will not go upstream I expect, but feel free to send it. The intention for Precise (3.2) was indeed to address this specific machine, since backporting the commit Joseph found would be too intrusive, and this I think avoids a lot of potential for regressions, although it's not generic enough to potentially fix more machines. I felt more confortable with quirking only for this machine, but may be it could be checked manually for ALC269 in the code where speakers are etc. to force choosing a config that makes a headphone slider separated from speaker possible.
