Thinkpad hda regression in 3.3

Thinkpad hda regression in 3.3

[Josh Boyer]

Hi Takashi and Jaroslav,

We've had a number of bugs reported about sound not working correctly on
various models of Thinkpad machines in the 3.3 kernel.  I've listed them
below.

I looked through the commits and found:

    commit 29c5fbbcfefba5225a6783683c46c39e10877703:

    ALSA: HDA: Use model=auto for Thinkpad T510

    The user reports that model=auto works fine for him. Using
    model=auto bring in new features such as jack detection notification
    to userspace.

I did a local build here with that comment reverted and so far most of
the people reported their sound to be working again.  The trivial revert
patch is below in case you want it.

It seems there are multiple models that have PCI ID 17aa:215e and using
model=auto does not work for them all.  It particularly messes with
machines using a docking station for some reason.

Aside from just reverting the above commit, do you have other thoughts
on how to fix this?

Subject: [PATCH] ALSA: hda - Use model=thinkpad for PCI ID 17aa:215e

Commit 29c5fb "ALSA: HDA: Use model=auto for Thinkpad T510" switched to
using model=auto for PCI ID 17aa:215e, however that breaks sound on a
number of thinkpads.  Change this back to using model=thinkpad for now.

Could you get alsa-info.sh output on the non-working T510?
If it's really about the built-in speaker or headphone jack, I doubt
it's rahter the muted output in mixer.  I see only "me too" in the bug
report, which doesn't help much to diagnose the problem.

I've got a few positive feedbacks of T410 and T510, so basically the
driver should work.  But I know the problem of docking-station (see
below).

The problem regarding the docking station is basically a BIOS issue.
ThinkPad BIOS doesn't expose the pins for docking stations at all.
We have already a workaround for X200, and similar others would be
needed for T410, T420, etc.

For testing, you don't need even patch the driver.  When the driver is
built with CONFIG_SND_HDA_PATCH_LOADER=y, create a file containing the
below as /lib/firmware/alsa-tp-dock:

================================================================
[codec]
0x14f15069 0x17aa21a4 0

[pincfg]
0x1a 0x21a11000
0x1c 0x23014250
================================================================

then pass the module option patch="alsa-tp-dock" to snd-hda-intel,
e.g. create a file containing below in /etc/modprobe.d/*

	options snd-hda-intel patch="alsa-tp-dock"

This will override the pin-default values of 0x1a and 0x1c, which
corresponds to the docking-station mic and docking-station output.
This will set dock-out as the line-out so that the built-in headphone
is preferred over it.

Note that after applying this, the new mixer elements will appear, so
you'd need to adjust the values manually once.

Similarly, for T420, create a file with the contents below instead:

================================================================
[codec]
0x14f1506e 0x17aa21d2 0

[pincfg]
0x19 0x0421104f
0x1a 0x21a19050
0x1c 0x2121401f
================================================================

The rest procedure is same.

If the above seem work (again, make sure that you adjust the mixer
mutes and levels), I'll make kernel patches to add these fixups
statically in the driver so that it works without extra patching.

Takashi

OK, I've asked for that.

The above is for the X200 docking station, correct?  So it should work
with an x201 thinkpad in an x200 dock.

OK.  I'll have the reporters test this out.

Forgot to mention that the above is only for TP410/510.
For TP420 & co, the second one should be used.

Also, for TP410/510, the following values might be better (this time
contains 0x19, too):

0x19 0x042110ff
0x1a 0x21a190f0
0x1c 0x212140ff

This will make the built-in and the dock headphones as headphones.
The mixer elements will be more intuitive than the former version.

Thanks.  As mentionted, the difference between two setups (sent in two
posts) is seen in the mixer setup.  I personally don't mind which
setup is taken; it's rather a choice of users.  So, let me know which
setup is preferred by testers.

The reason behind such multiple setups is that the codec chip has only
two DACs while you want to access for three or more outputs (two
headphones, one speaker, etc).  Thus some outputs must share the same
DAC.

You're referring to the inclusion of pin 0x19 or not here, right?

I'm guessing when someone undocks the pins are reconfigured back to the
jacks on the laptop itself somehow?

I must admit, ALSA and it's multi-codec hda driver with lots of pin
swizzling is somewhat intimidating at the moment.  If I ask stupid
questions, please bear with me :).

No, the configuration must be determined at the driver initialization
time.  So, the mixer elements stay unchanged with or without dock.
(For example, if the mixer elements were to change upon the
 dock/undock, this would be really confusing both for users and apps.
 In theory, it's possible to implement like that, but no one wants
 it.)

The jack-detection on the docking station works, yes, i.e. the
auto-muting or the mic changing works.  But it's different from
changing the configuration on the hotplug of docking station itself.

Looking through alsa-info.sh outputs from various ThinkPad models I've
gathered, it seems that we can use the same pin setups for all.

Below is a test patch for 3.3 kernel.  (Note that it'd give a merge
conflict for 3.4 kernel.)

We had a user try the alsa-tp-dock patch on an X201 and it didn't seem
to work for them.  See bug
https://bugzilla.redhat.com/show_bug.cgi?id=806217

Perhaps the [codec] section isn't set properly for their configuration?
The alsa-info for their machine is in comment #9 of the bug.

OK, I'll do a scratch build with this and get people to test.

Right.  This must match with the actual values.
Or the recent driver accepts 0 as the the second value.

In that case, check whether the reported machines have the

I built your patch in a scratch kernel and have at least one user with a
t510 laptop report success.  Christoph reported the mixers showing up,
but it wasn't clear to me if his sound actually worked on the x201.
I've CC'd both users (Kevin t510, Christoph x201 in a dock).

Good.  Should I wait for a copule of days for the test results before
merging the patch, or go for now?
