Comment 21 for bug 1332900

Update:

I reinstalled alsa-daily and I was able to get 'hda jack retask' to function. I choose show unconnected pins and advanced override. Raymond suggested a couple of nodes that might be the internal speakers for this model. I tried experimenting by checking "override" and setting to "speaker", "internal" etc changing various settings. I am not sure what I should set these to or if they are just labels? Does it matter? Regardless, it does not seem to affect anything in speaker-test. One thing I should note though is that somehow now the speaker-test has sound only coming out when displaying "LFE". Previously sound was only coming out of one channel, however sound would come out of that channel while displaying "front-left", "front-right"...etc. Nothing has really changed though in regards to the actual sound, only what is displayed on the screen while testing has changed, so maybe just the config? So, now I have only sound coming out of LFE (as before) but now it only
comes out when "LFE" is displayed, rather than playing sound while the
other channel names are displayed.

Secondly, When I use "override", I see that it adds a control to "alsamixer", however it doesnt add a full bar, but rather just says "00" and is at a fixed position in alsamixer. I am uncertain if this is normal. At this point I dont fully understand if all of these are making up one collective, or if I should be able to adjust each one separate. I would assume because it is a laptop that there should only be one Master control in alsamixer?...and that sound should be automatically mapped to each present speaker. Let me know if that is correct.

If that is the case, then I am still hung up with detection of those "missing" speakers. Why are they not detected automatically and am I on the right track using 'hdajackretask' to get them detected/assigned?

I could not find a guide on using hdajackretask, so I just need to know what settings to use and i assume I just trial and error by hitting "apply", then doing speaker-test to see if any others show sound? If that is the case, however ...why was i told i was getting sound on (4) of those speakers, but in actuality it only came out of (1) of them, while displaying each one.

I am just trying to understand why it does not display the actual speaker which is playing. The only idea i had was that sound is right now mapped only to the subwoofer and so when it does the test right now for each speaker, the subwoofer receives the test for each instead of the missing speakers. So, I need to know how to reassign it so that the subwoofer only receives the test for the subwoofer, and the other 2 speakers receive their own test signal.

I hope this makes sense.

P.S. - Many of the suggestions have to do with the Headphone jacks, but my problem is related to the internal speakers. As far as I understand, they are separate issues?
