Bug Description

This bug is similar to the following, but affects the REALTek ALC883 chip set.
In brief: before adding the line "options snd-hda-intel power_save=0 power_save_controller=N position_fix=1 enable=yes" to my /etc/modprobe.d/alsa-base.conf file, I could hear sound from the mic and line-in jacks through my speakers and control it with the GNOME-alsamixer (both muting and volume) but I could not record that sound stream with any software. Adding the position fix seems to have done the trick.
Please let me know if you need more info that is provided below.
All the best,

Can you verify that *only* position_fix=1 is necessary? You seem to be
using a model quirk, too:

model : 6stack-dig,<NULL>,<NULL>,<NULL>,<NULL>,<NULL>,<NULL>,<NULL>

Seems that the quirk is not necessary. I had been trying fixes for other
problems and that was an artifact of that.

Looking at the reports from the script, it seems that the model 6stack-dig is automatically assigned by the software. I had tried to set it to 3stack-6ch and it was showing both that and the 6stack-dig in the Modprobe options (sound related) section, but was only loading the 6stack-dig module options. Even with the option commented out, the 6stack-dig is still showing up (report here: ).

Daniel T Chen (crimsun) wrote :

"automatically assigned by the software" isn't the case; generally this means that you've left a configuration file in /etc/modprobe.d with the option active.

grep -n 6stack /etc/modprobe.d/*

Reuben Bailey (reuben-e-bailey) wrote :

Well, so I did. I had made a copy as a backup, but (not realizing how things work) had left it as a .conf file... Anyhow, the model quirk of 6stack-dig is required to activate the inputs. The 3stack-6ch does not work, and leaving it blank also does not work.

Reuben Bailey (reuben-e-bailey) wrote :

blank as in commented out or deleted.

Daniel T Chen (crimsun) wrote :

So, just to be clear, you need both model=6stack-dig *and* position_fix=1?

Reuben Bailey (reuben-e-bailey) wrote :

link to Ubuntu forums above is incorrect. Here is the correct one...
seems as though the "t" got changed to a "p" in the first one I posted.

     That is what it has needed for me, yes. If the position fix is not there, the data stream from the sound inputs is not picked up by anything beyond ALSA. If the model is not there, no sound comes through at all.

Hmm. Let me restate that a little more clearly:

If neither the position fix or the model are present, no sound comes
through the speakers (plugged ito the speaker out jack) when there is input.
If the position fix is there but the model is not, the result is the same.
If the model is there but no position fix, I can hear sound from the
speakers and control the volume with the ALSA mixer, but no other
software picks up the stream.
If both model and position fix are present, I can hear the sound
directly from the speakers and all software picks up the stream.

Please note that there is an existing quirk for your hardware: model=3stack-6ch

Please verify with linux-alsa-driver-modules from ppa:ubuntu-audio-dev after a reboot that the existing quirk (which you also noted above) is incorrect.

Added the repository and installed the package, replacing the backports
module. Could not boot into the most recent kernel (2.6.30-20) in either
regular or recovery modes - one CPU would hang (soft lockup - CPU#1
hangs for 61s modprobe 622). Booted into 2.6.30-19, removed
linux-alsa-driver-modules and reinstalled equivalent backports. I can
now boot 2.6.30-29 with no problem. I was not able to find a
meta-package for the linux-alsa-driver-modules package - I don't know if
that makes a difference or not.

On the motherboard there are contacts where an SPDIF connector could be
located - there is no connector present.

Hmm, do you mean Karmic's most recent released kernel, 2.6.31-20? (I think you may have meant 2.6.31 instead of 2.6.30.)

Yes, I did mean 2.6.31-20. Sorry about that.
