--- Comment #28 from Steffen Jost
1) Docking station line out detection works fine, even in conjunction with un-/docking the laptop. :) There is a small problem with precedence in a rather unlikely scenario: If everything is connected, then sound is heard over the laptop's line out (headphones in my case), as it should be. However, unplugging the silent external speakers from the docking station then causes the headphones to fall silent and the internal speakers to come alive. Re-plugging the external speakers (docking station jack) then switches sound back from the internal speakers to the headphones (laptop jack). I suppose the headphones should remain on throughout in this admittedly rare scenario. 2) Microphones work over the docking station line out, but the labelling seems strange to me: "Mic" -> Laptop's Jack "Front Mic" -> Docking Station's Jack "Digital" -> Built-in Microphone 3) Sound quality of the built-in mic still seems somewhat worse than it used to be, but I might not recall it correctly. Best quality is achieved by reducing "Capture" to 60% and setting the slider labelled "Digital Mic", which I cannot see in alsamixer, but only in Kmix, where it has 4 settings to 2 (second lowest). Also very odd: Skype is now automatically adjusting the slider "Digital Mic" and not "Capture" as it did before. 4) Alsamixer shows fewer sliders than Kmix. In addition to the aforementioned "Digital Mic", I also see the "Mux" and "Mux2" in Kmix. However, I could not figure out their effect. Especially, they do not control the volume of the external nor internal speakers. 5) Do you know already which future alsa driver version number will feature this working setup for the first time? I am unfamiliar with the numbering scheme, but I would like to update the Suse Hardware Compatibility List Wiki (and I also want to inform colleagues using the same hardware). Or will this be Novell/Suse specific only? -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
