No sound on nitrogen6x + linux-boundary 3.10.17

[Erik Botö]

Hi,

I'm having trouble playing audio on this board using the sgtl5000. Can
anyone verify that it works on their system? Also any ideas of what
might be wrong are highly appreciated :)

Using aplay it get stuck here:

And using gst-launch with alsasink and GST_DEBUG=*:5 I get stuck on an
endless row of:

Update:

I built the exact same image but using the 3.0.35 kernel and then
playback works fine.

Re: No sound on nitrogen6x + linux-boundary 3.10.17

[Erik Botö]

I measured the different clock signals to the sgtl5000 chip and they
seem to be running at least. Approx 1,4 MHz I2S_SCLK, 44100 Hz sample
rate and SYS_MCLK is ~23 MHz. Those are similar with the older kernel,
except SYS_MCLK which seems a bit lower ~16 MHz.

Cheers,
Erik

I remember that I have helped John Weber recently to get audio working
on 3.10.17 on wandboard.

There were two patches that were needed:

https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/sound/soc/codecs/sgtl5000.c?id=9e13f345887c179068bbc1f7389b7177bf88f57e

This could be related to the problems that I saw in Wandboard.  The SGTL5000 
would not be properly initialize if I passed audio through it /and/ then 
rebooted the board (any type of reboot).  Fabio's patches worked to solve the 
problem.  It would be good to know if this fixes your problem.

I'm out of the office today, but CC'ing Troy to see if he can reproduce
things.

I just did a similar fix for the problem, but I also reset registers to power on
default value.

Like this one, I guess:

Yes, but without regmap.

Essentially yes.

Troy pulled in an older patch that also has some retry logic
around I2C reads and writes:
	https://github.com/boundarydevices/linux-imx6/commit/c8e4e642

Erik, I'll forward a patch against linux-boundary_3.10.17.bb later
today, but you can test by changing SRCREV to

I tried that now but I still can't play anything using alsa (or
anything else I've tried). Note that this is not just after reboot, I
also don't have working audio after a cold boot. Looking at the kernel
output from boot it looks like the driver load just fine, and I have
the device under /dev/snd/pcmC0D0p and it's listed using aplay -L:


Has anyone been able to test using a sabrelite or nitrogen6x to see if
they get the same result? I just use aplay to play a test file from
alsa (/usr/share/sounds/alsa/Front_Left.wav on most linux systems).

I just tested against this image, revision fe41f1e of our kernel
and nitrogen6x_defconfig on a Nitrogen6x and things worked
perfectly through a handful of re-boots:

	http://boundarydevices.com/yocto-kernel-3-10-17-beta/

Let me know if you'd like me to upload a binary kernel package.

Thanks for helping out!

After testing this out and getting really confused about it still not
working I started to look through the early boot output on the serial
console looking for some board revision info. Then I noticed that it
used the sabrelite version of the device tree file since board was
unset in u-boot. By doing a "setenv board nitrogen6x" in u-boot before
booting, which makes it use the correct dtb-file, sound works like a
charm. So I guess it was a user error all along, although a
not-so-obvious one :)

After upgrading u-boot on the board from "U-Boot
2013.01-00058-g5957f6d" to "U-Boot 2014.04" the board variable is set
by default and hence everything works out-of-the-box.

Again, thanks for your patience!

Cheers,
Erik

No problem. That's what we're here for.

Thanks for the note about this. Since upgrading U-Boot is a
separate operation for our boards, we'll likely have others
hit the same thing as they make the transition to DT.

Maybe you want to backport this patch into your 3.10 branch as well.

It fixes suspend/resume on sgtl5000:

So I tried to apply the following commits from the wandboard kernel
git, they didn't apply cleanly but I think I was able to get their
function in:

ASoC-sgtl5000-Convert-to-use-regmap-directly
ASoC-sgtl5000-Read-SGTL5000_CHIP_ID-in-i2c_probe
ASoC-sgtl5000-Fix-driver-probe-after-reset
ASoC-sgtl5000-Let-the-codec-acquire-its-clock
ASoC-sgtl5000-defer-the-probe-if-clock-is-not-found

But unfortunately I still have the same problem.

I measured I2S_SCLK, I2S_LRCLK and SYS_MCLK on the sgtl5000 chip using
both the 3.10.17 and 3.0.35 (alsa playback works on 3.0.35 but not
3.10.17):
                       3.10.17           3.0.35
I2S_SCLK       ~1.4 Mhz      ~1.4 Mhz
I2S_LRCLK     44100 Hz      44100 Hz
SYS_MCLK    ~23 MHz     ~16,5 MHz

Looking at the datasheet [1] it looks like things are setup
differently depending on if SYS_MCLK is > 17 MHz which is the case
with 3.10.17. Currently I'm a bit confused about how this clock get
set up.

I'm a bit out of my regular comfort zone here so if you think I'm
wasting my time looking at SYS_MCLK please tell me :) If anyone using
sgtl5000 + 3.10.17 with alsa playback working has an oscilloscope
nearby I'd would love to know how your clocks look.
