Comment 3 for bug 871582

Hi David, I have tried to document all the procedure here, so you can have a look at it. The attachments have the various steps in the procedure of fully uninstalling alsa/pulse, reinstalling, dkms, alsa-base.conf, modingo snd-hda-intel, etc.

The results (things changes a bit from previous behavior). Testing with media player (Clementine):

1) Plugging / Unplugging Headphone to Front Green Connector:
Sound on External Speakers (Rear Green Jack) AND Headphone. No Speaker muting. No changes to volumes. No moves on alsamixer sliders.

2) Alsamixer MASTER Slider
Controls Speakers and Headphone volumes.

3) Alsamixer HEADPHONE Slider
Controls Nothing. No changes when moving slider up/down to Speaker or Headphone.

4) Alsamixer PCM Slider
Controls Speakers and Headphone volumes.

5) Alsamixer FRONT Slider
Controls Speakers and Headphone volumes

So although things are indeed different now, we can't actually say that it works as we were expecting it to. But thank you so much for your efforts.

Regards,
EFfenberg
