Comment 26 for bug 871611

It's still not completely solved. I am running Mint 13 Maya:

Problem A) as saepia said - one has to manually add "options snd-hda-intel ..." and do some "alsa force-reload" or restart to fix the "1. speaker ->2. headphone insertion ->3. speaker-not-working-anymore" issue

Problem B) but still the "Speaker" volume 0% <= Ss1 <= 100% of 1. is not remembered, but instead it goes to 100% on 3.

Problem C) and the "Speaker" volume (curiously adjusting the headphone volume as well) 0% <= Sh2 <= 100% of 2. is not remembered on "->4. headphone insertion"

=> it seems the logical<->physical relationship between the "Soundcard elements": "Speaker" and "PCM" is not correctly mapped by the driver:

State X) currently:

State Xs) no headphone inserted: "Speaker", "PCM" and "Master" add up to the resulting volume of the notebook speakers VS
      => thus 3. is actually quite bad here since it may significantly increase speaker volume VS3 in opposition to VS1 (=VS3-(1-Ss1))

State Xh) headphone inserted: "Speaker", "PCM" and "Master" add up to the resulting volume of the headphone VH
      => thus 2./4. are actually quite bad here since they may significantly lower the headphone volume VH2/VH4 (VH4=VH2-Sh2)

=>
Solution Y1) driver behaviour should be: B and C "Speaker" volume should not be touched at all on headphone insertion/removal, which would also eliminate the problem of the "remembering of the speaker/headphone volume"

maybe some existing "model=???" other than "auto" may already do Y1 ... if I find time I'll play with this
