This is what your BIOS sets up. The main output is connected to the docking station. That's why "Front" (a silly name for ALC262; it should read "Line Out", maybe will be renamed in later versions) switch doesn't work. OTOH, all outputs (speaker, headphone and line-outs) use the same DAC, and this is controlled via line-out volume, i.e. "Front" volume. > So there are now 3 vol controls that affect both speakers and headphones: > * Master (which appeared somewhere between 2.6.24 and .25-rc1), when set to > zero, the sound is still audible in speakers and headphones This must be the behavior of the codec chip... Did "Front" volume 0 mute in the earlier version? If not, it actually doesn't mute with the lowest volume. Use the master switch to mute. Anyway, attach the alsa-info.sh output at the moment Master volume is zero. > * PCM, working as expected (0 volume = no sound) > * Front (0 volume = still audible sound) > > So it is usable now (and those Speaker and Headphones on/off switches make > sense), but kinda suboptimal. (is it my BIOS who is to blame?) Yep. For the perfect solution, you'd need to create a static "patch" for this particular model instead of auto-configuration. Then you can adjust everything as you like.
