ASoC: wm9712: Microphone doesn't work, "Capture Volume" inverted

[Christoph Fritz]

Hi Mark, Liam, Hans J. and List,

 I have a "wm9712" codec-chip on an ARM mx35 board and everything works
except Microphone.

Strange is that I can't change the Mic-Select-Source:

# amixer sset "Mic Select Source" 'Mic 2'
Simple mixer control 'Mic Select Source',0
  Capabilities: enum
  Items: 'Mic 1' 'Differential' 'Mic 2' 'Stereo'
  Item0: 'Mic 1'

When I tested arecord for line-in, the "Capture Slide" in alsamixer was
wrongly inverted.
in sound/soc/codecs/wm9712.c:
       SOC_DOUBLE("Capture Volume", AC97_REC_GAIN, 8, 0, 63, 1),
should get:
       SOC_DOUBLE("Capture Volume", AC97_REC_GAIN, 8, 0, 63, 0),
If you want I can send a patch in.

I'm using the current linus git tree (3.4.0-rc4). I tried it with
linux-2.6.33.20 (with sound/soc/imx/imx-ssi.c etc. from 2.6.34) and it
works. On a fairly similar board I was told that it works on Kernel
3.0.4 with this patch applied:

Since patch "ASoC: Sync initial widget state with hardware"
(commitid: b66a70d5e9929f3b0df5a7177bba75652d2f4c3e) the mic capture doesn't
work. The MICBIAS bit from the "Power Management" Register are alway 1 (disabled).
So that the captering works the active status must be set to 1, at the right time.
That this works the stream name must be set.

Nothing springing to mind here, can you see logging for the register

Yes, please.  In general this is always a good thing to do if you spot
an error in the code.

This analysis seems a bit confused - how does changing the initial state
affect the dynamic changes at runtime?

This isn't right, the mic bias clearly shouldn't be associated with a
stream as you can do capture without microphone (eg, from a line input)
and you can have a bypass path with no capture.

I added some printks into ac97_write() "sound/soc/codecs/wm9712.c" and
when I do for example change "Item: Mic Boost [dB gain: 20.00] " I get
this:

 write  eh 8000  [6808]
 write  eh 8000  [6888]

but when I try to change "Mic Select Source" or "Item: Differential
Source", nothing happens here.

And in "sound/soc/codecs/wm9712.c":

static const struct soc_enum wm9712_enum[] = {
SOC_ENUM_SINGLE(AC97_PCI_SVID, 14, 4, wm9712_alc_select),
SOC_ENUM_SINGLE(AC97_VIDEO, 12, 4, wm9712_alc_mux),
SOC_ENUM_SINGLE(AC97_AUX, 9, 4, wm9712_out3_src),
SOC_ENUM_SINGLE(AC97_AUX, 8, 2, wm9712_spk_src),
SOC_ENUM_SINGLE(AC97_REC_SEL, 12, 4, wm9712_rec_adc),
SOC_ENUM_SINGLE(AC97_MASTER_TONE, 15, 2, wm9712_base),
SOC_ENUM_DOUBLE(AC97_REC_GAIN, 14, 6, 2, wm9712_rec_gain),
SOC_ENUM_SINGLE(AC97_MIC, 5, 4, wm9712_mic),
SOC_ENUM_SINGLE(AC97_REC_SEL, 8, 8, wm9712_rec_sel),
SOC_ENUM_SINGLE(AC97_REC_SEL, 0, 8, wm9712_rec_sel),
SOC_ENUM_SINGLE(AC97_PCI_SVID, 5, 2, wm9712_ng_type),
SOC_ENUM_SINGLE(0x5c, 8, 2, wm9712_diff_sel),
};

Why is wm9712_enum[0] never used?

Is "SOC_ENUM_SINGLE(0x5c, 8, 2, wm9712_diff_sel)," correct? Because of
the ">> 1" shift in ac97_write() ?

Odd.  Can you see the write actually happening on the bus?

I rather imagine it's just a simple case of the feature having being
missed when the driver was implemented.

ac97_write() doesn't get called when I try to change "Item: Differential Source".

Oh, right - you're not actually seeing any attempt to write.  There
won't be anything on the bus, then.  Still, why are you identifying the
shift there?  The write will be suppresed if the register contents don't
change which looks like what you're seeing here - though I can't see
anything obviously wrong with the enum from looking at the code, it's
saying that the enumeration exists in bit 8 of register 0x5c...

The shift should be fine here.

I can't immediately think of any reason, no - I'd step through or
annotate the code and have a look.

I'm still on.

And while testing WM9712 its touchpad interface, connecting a 800x600
display (instead of the default 640x480 one) results in a gone sound and
input-device - pretty queer:

WM9711/WM9712 SoC Audio Codec 0.4
asoc: platform pcm constructor failed
asoc: can't create pcm HiFi
asoc: failed to instantiate card PhyCORE-ac97-audio: -12

I have to admit that I used this time a 3.2 kernel. I'll test with
current later these days.

Same behaviour with 3.4.0-rc6:

Framebuffer driver mx3fb configured for a 800x600 display:

mx3fb configured for a 640x480 display:

  snd_soc_register_card()

When I do decrease from 800x600 to 800x594, wm9712 works.

It seems to be a dma problem and not directly related to wm9712.


But the not working microphone input still bothers me. I suppose this
is related to not beeing able to change some muxes:

$ amixer sset "Mic Select Source" 'Mic 2'
 Simple mixer control 'Mic Select Source',0
   Capabilities: enum
   Items: 'Mic 1' 'Differential' 'Mic 2' 'Stereo'
   Item0: 'Mic 1'

$ amixer sset "Differential Source" 'Line'
Simple mixer control 'Differential Source',0
  Capabilities: enum
  Items: 'Mic' 'Line'
  Item0: 'Mic'

They refuse to change their Item0 because they are defined as
SND_SOC_DAPM_MUX without a correlating path->name so that
snd_soc_dapm_mux_update_power() (in sound/soc/soc-dapmc) doesn't
change anything.

It works in 2.6.33, but current kernel has different mux handling and
it seems that no one since cared that much about microphone support.

Mark, can you confirm this, purpose a fix or even come up with
a patch?

A route into a mux without a path name (other than a supply) just isn't
meaningful and I'm surprised it ever worked.

It's nothing to do with microphones really, it's more that AC'97 CODECs
are rarely used with modern kernels as the boards that use AC'97 are
mostly quite old and suffer performance issues with modern software
stacks so newer kernels haven't been getting much testing with them.

> Mark, can you confirm this, purpose a fix or even come up with

Just filling in the appropriate mux value in the relevant route should
do the trick.  Looking at the code it looks like the widget isn't hooked
into the audio routing map at all so I'm a little surprised.  I'm out of
the office at the minute and so can't readily set up a test system
myself.

Thanks Mark, I'm pretty interested in testing too :-)

Do you mean filling in to wm9712_audio_map or wm9712_enum?

Does that mean that wm9712_dapm_widgets should be referred by a
struct snd_kcontrol_new ?

I'm not that into alsa and would greatly appreciate if you could have
a look with your test system.

There will need to be routes in the audio map.  Don't know if there are
any fixes needed in the enum, it was the routing I noticed was missing.

No, that should never happen.

For personal reasons I don't really have an ETA for when I'll be in the
office, sorry.

I'm not entirely sure you've looked at the code here...

The driver knows exactly which registers are volatile and takes
advantage of this - this is entirely idiomatic for devices like this and
not really that hard to get right.

That's...  horrifying, really.  The WM9712 really isn't at all complex
by modern standards for that matter, but the idea that it's common to
have devices with documented registers that might spontaneously change
in normal operation doesn't seem at all clever.  What happens if the
configuration that was set was important?

> all corner cases. And what about things like dirty supply voltages or EMI?

If you've got that sort of problem with supply quality or EMI there's
obviously a very serious system issue to contend with, one that
typically requires highly aggressive action to resolve - you're starting
to get into games like having to constantly poll the device and restart
it if you detect that it fell over which isn't pleasant and most likely
means you've already hit serious user visible consequences.  Things like
device initialisation will need to be redone, for example.  I can only
think of one driver that takes such measures, and it's actually relying
on restore from register cache for part of the recovery :)

That said, many devices will get a moderate degree of robustness against
this through power saving - the closer the device can get to cold during
idle the better from this point of view, and in many cases it's possible
to completely power down the device when idle.  A common idiom is to
take the device down to cold when idle then dump the setup changes that
don't need sequencing into the device from cache before doing the bits
that need sequencing, especially where many of the register settings can
be mapped direictly into userspace.

Indeed I'm not sure a cache isn't a bad plan for detecting this sort of
thing; if you find the cache values diverging from the physical values
for non-volatile registers you know something's up.

For the sort of devices we're talking about here it's way more than a
few clock cycles that are involved, you're talking about fairly slow
and at times congested buses like I2C here.  Never mind what happens
when someone decides to use a bigbanged controller, which is more common
than one might dream of.  Obviously if you're on a bus with trivial I/O
costs the tradeoffs vary but for the sort of buses we're talking about
it's much easier to see a win.

Indeed with many older devices readback just isn't physically supported
in the first place so if you want to do any kind of readback based thing
you're going to have to cache in some way.  This was true for the
majority of devices at the time WM9712 was new.

I don't actually think desktop drivers bother with this much, though 
ICBW.  They relatively infrequently use the slow buses.  I'd suggest
reporting the issue, anyway - it's probably more constructive.

> Fortunately, most other subsystems would never accept such code for mainline.

This is actually a standard feature of the regmap API that drivers can
use if they want, there's a bunch of device classes where it can offer a
useful win (those that typically have slow control interfaces and not so
mnay volatile registers).
