Forward to upstream or whatever. I'd like to bring the sound back on my Bentley.

Thanks.

Hi kotqiue and thanks for reporting this bug!

Could you help me by confirming that this still occurs with the latest updates, in particular, the latest released kernel (3.2.0-32)? If so, could you please supply an alsa-info according to https://wiki.ubuntu.com/Audio/AlsaInfo

Thanks!

[Raymond (superquad-vortex2)]

there.was a model lg but your pci subsystem id don't match

if it work on 2.6 kernel, try to boot with 2.6 live cd and obtain the output of alsa-info.sh

http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commitdiff;h=ae6b813a4dbba2713df497c032798b845289653f;hp=b3b0abe11d606fa2344793edd3d69b98b430b0d4

[kotique (kotique)]

I booted 11.04 and collected the info. One small thing - sound doesn't go through built-in speakers on laptop, but plays when I connect headphone into green jack. Anyways, that's a progress -- at least the driver doesn't oops there...

http://www.alsa-project.org/db/?f=7f46be549e688b0e9217022de35113db663c6cda

Raymond, I tried modprobe snd_hda_intel model=lg, same result, it just sticks to "autoprobing". Maybe I could add pci id to LG model there?
Oh, and btw, why is it selecting ALC883 when " lg LG laptop (m1 express dual)" is in ALC880 section?

Thanks!

Analysis:

Under the 3.2 kernel, the Realtek codec driver tries to generate some kind of 10-channel surround output mode, out of your two mic input jacks and your two line input jacks. Do you really have so many jacks, btw?

The code is generating an OOPS because SND_CONFIG_DEBUG is not set, causing snd_BUG_ON() not to evaluate in alc_get_line_out_pfx:

 if (snd_BUG_ON(ch >= ARRAY_SIZE(channel_name)))
  return "PCM";

We might need an additional patch to take away the extra mic & line if you don't have them, but this should fix the oops at least.

With cc to stable it should reach 12.04 in some time, but if you want to fix it for yourself before that, you can follow this procedure: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

here you go with jack photo: https://picasaweb.google.com/lh/photo/qYuSii25N6W7_rxTd7xwgipMqeOizf5syumxy3i3sww?feat=directlink
So 2 jacks on laptop + internal speakers and internal microphone.

David, I'll try the patched module soon.

[David Henningsson (diwic)]

Thanks. It could be that the headphone takes a TRRS headset jack also, and that would be the extra mic, and that you have dual arrays of internal mic. But it could also be that BIOS is wrong when it advertises an extra mic and an extra internal mic.

[kotique (kotique)]

David, noah, it's a notebook from 2006, it won't have dual mics. The green jack outputs s/pdif laser beam when digital output isn't muted. I just tried your change to latest dkms-alsa from that page and it worked perfectly. I can hear sound from internal speakers in default config. I get sound through headphones when connected to green socket, so everything works as expected.

Though I heard very distorted sound from VLC when trying to play music in default config (directly to alsa?), but changed it to play through pulseaudio and now everything's fine.

Thanks for fixing this!

post the output of alsa-info.sh after you plugged in headphone and ext mic

the value of the hda jack kcontrol is true in the asound.state when the jack is plugged, so you can find out which pin complex is headphone / ext mic

need a pin fixup to make some pin complexes as [N/A]
