Comment 12 for bug 556663

No, enable_msi=1 is not sufficient.

When you say "don't split module options across lines" do you mean it should be multiple options on one line like this:

options snd-hda-intel enable_msi=1 model=test

I tried "options snd-hda-intel model=test" but without "enable_msi=1" and got the same result as before. That is, sound only with headphones, but plugged into the mic jack. No sound from speakers or headphone jack.

I ran the alsa-info.sh script again, with this setting:

options snd-hda-intel model=test
