[Kernel-packages] [Bug 1234252] Re: [MacBookPro8, 1, CS4206] Left speaker low volume and absence of low freqs
It seems I found the answer to my question/bugreport. My macbook pro 8.1 13-inch really has 3 speakers: left, right and so called (by Apple) subwoofer - standalone additional speaker, which is located on the right side (this is important!). It is a really new thing for me (after 2 years of using laptop). So alsamixer (and intel-hda driver) is absolutely correct naming one of the controls as Bass speaker. Other items in alsamixer are: Master, Speaker, Headphone and PCM. Now the important thing: if I set to 0 right channel of Speaker in alsamixer, the left sounds like it was in Mac OS in the same mode (balance shifted to left speaker) - that is the right way how the balance should work! But balance slider in Ubuntu sound panel (let's call it slider U) works very strange: at first, when i start to move it to the left - alsamixer's Speaker right channel (slider A) goes down as it should be. But when slider U is approx. 5% till the end, slider A is already 0! At this point the sound is ok (coming from left speaker, but with bass as it should be). And if I continue to move slider U till the end, I see right PCM going down dramatically fast in alsamixer. And now the sound is incorrect (as stated in my bugreport). So I can say that when in normal mode (balance set to 50/50) the sound is ok and identical to Mac OS. The questions are: 1) Why does ubuntu's sound panel (and pavucontrol too) treat subwoofer speaker as the right one? 2) Why does ubuntu's sound panel balance slider behave in such strange way (described above)? 2) Why is the subwoofer speaker included in right channel of PCM control (in alsamixer)? Overall, I am happy to solve this puzzle (the answer looks so simple if to look back). Please tell me, should I post a new report(s) or leave it as is?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.12 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as Confirmed. Thanks in advance.

Well, hda-analyzer tool running in monitor mode shows that volume level of Bass speaker changes while moving corresponding sliders (left and right) in alsamixer, but those changes affect only right channel. Feel free to ask me for additional info/logs or for triyng defferent versions of kernel etc. I can ever totally ruin current installation with no sorrow, cause my main goal now is to struggle that bug and make ubuntu my main OS on that laptop.
