Sound capture (microphone) works on LiveCD, but don't work after installation

I've pushed a patch for this to stable@ and upstream.

The abovementioned fix is now upstream in kernel 2.6.32.16.

SRU Justification

Impact: The upstream process for stable tree updates is quite similar in scope to the Ubuntu SRU process, e.g., each patch has to demonstrably fix a bug, and each patch is vetted by upstream by originating either directly from Linus' tree or in a minimally backported form of that patch.

The 2.6.32.21 upstream stable patch set is now available and contains fixes for this problem. It should be included in the Ubuntu kernel as well.

Related commits in the Lucid repo are:

8cbe9bd ALSA: hda: Use LPIB for Acer Aspire 5110

Accepted linux into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

Could people affected by this please test the proposed kernel and let us know whether the issue is resolved? We are awaiting confirmation that the problem is fixed by the proposed kernel.

See the previous comment for information about how to get proposed kernels.

Thanks!

I have proposed kernel installed (2.6.32-25-generic).
I did next:
- delete string:
    options snd-hda-intel position_fix=1
  from file /etc/modprobe.d/alsa-base.conf;
- restart notebook;
- look into sound capture monitor (no reaction on microfon voice);
- try sound recorder (no sound capture);
- try skype (no sound capture).

My actions are correct?

...hm cross-posting via email may or may not work. Manually adding and hoping LP does not think otherwise later...

This is updating a set of bugs, so things said may or may not be exactly matching the bug report itself.

There is a set of bug reports which, reading feedback from reporters, do not seem to be fixed by the patches which were thought to fix them. All of these patches are part of some upstream stable release, so if a real fix is found, it
should be submitted there as well.
Quickly reading over the reports they all seem to be positional quirk fixes in ALSA. In one of the reports David had a quick look and had the suspicion that the code path of activating the fix may not be hit at all.
So while not fixing the bug all patches are not causing things to regress. Due to automatic processes, these bugs will get changed by a bot to fixed when the proposed kernel moves to updates and the bugs need to be re-opened then.

David, Daniel, maybe you can have a look at the test feedback and find out why the quirks have no effect?

Thanks,
Stefan

I can confirm this bug in Ubuntu 10.10. Workaround in Bug Description still work.

@Leo David's patches fixing the core portion of this parsing landed some time ago but weren't in the Lucid release. Please follow https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules, and attempt to reproduce the symptom.

I just install Ubuntu 11.04. Sound capture works after installation. So issue fixed at this release!

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-lucid' to 'verification-done-lucid'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

lucid has seen the end of its life and is no longer receiving any updates. Marking the lucid task for this ticket as "Won't Fix".
