    Thumbs down kernel 3.8.0-14 : bad output sound

    ALC882 HDA Intel chip

    get a noisy "generic" sound output with that new kernel. Its a regression as the previous kernels works. What is new with that one : System Settings Sound has nothing listed (empty), so the hardware is not monitored.

    how is sound on your system with 3.8.0-14 ?

    Sound is fine here on my 64-bit desktop.
    I use Realtek ALC889A sound card.
    What is your sound card?

    You've made me peek into the abyss of propsed... No, sound is OK even with -14...
    Did You check udev upgrade?

    i was out for a while, so a cold boot later, that ALC882 chip is detected (can change the settings via the sound icon into System Settings) but when i start a sound stream (radiotray for example), i need to change the profile choice (analog output -> profile -> surround 4.0 -> surround 4.1) to get it activated.

    Thats it, i will see on the next boot if the sound chipset is detected (as now) or not (as the previous boot); seems erratic.

    note: the 3.8.4 kernel changelog has "ALSA: seq: Fix missing error handling in snd_seq_timer_open()"
    seems it has something to do with my sound issue.

    note2: looking at 3.9 kernel changes, i'm seeing that:
    "ALSA: hda - Fix typo in checking IEC958 emphasis bit"

    this is how that sound onboard chip is identified (numeric choice). So i need to test that vanilla one.

    Take contact with the kernel developers as soon as you figure out what's the kernel which has the bug.

    Acer Aspire 1 netbook with:
    Audio device: Intel Corporation NM10/ICH7 Family High Definition Audio Controller (rev 02)
    sound O.K. with 3.8.0-14 from BBC video. Now that's hardly a high definition source.....

    So far the only problem that I have had with 3.8.0.14 is the fact that Today's Build Failed the UEFI Security Check A.K.A. SecureBoot.

    Well, as i also use the gnome3-team ppa on that system, now the sound driver activation is well done; so i suppose that package(s) transition was to blame.
