Internal audio does not work on CYAN #317

Closed reynhout closed 6 years ago

reynhout commented 7 years ago

CYAN is the only Braswell with the Maxim MAX98090 audio chip.

Current kernel builds (4.9.4-galliumos) include drivers for this chip, but they are not loading properly and internal audio is not working.

Temporary workarounds: Bluetooth or USB audio.

ghost commented 7 years ago

What's the priority for this issue looking like?

reynhout commented 7 years ago

kernel.org thread here: https://bugzilla.kernel.org/show_bug.cgi?id=151521

Kernel 4.9.4 with the patch in c14 (but without the @plbossart patch for rt5450) yields some new log messages: https://paste.debian.net/913490

reynhout commented 7 years ago

Init of MAX98090 gets further along with @mildred's patch, but now we hit a null pointer deref in the jack configuration. Perhaps there are more bits to pull in from the ChromiumOS tree?

@anorom No, they're not working yet. I haven't had a chance to see if I can push things any further, but the patches as-is do not resolve the issue.

It looked like the patches would not fix the issue but your testing and feedback seems to keep things moving. Appreciate your help.

Velyro commented 7 years ago

How's it going so far?

jeffkub commented 7 years ago

I've been digging into the audio issue on CYAN, and becoming convinced its due to missing initialization code that chromeos does in the depthcharge payload.

https://plus.google.com/u/0/+TimoJyrinki/posts/R1AqYCSPru8

Here is the board setup function in depthcharge

https://chromium.googlesource.com/chromiumos/platform/depthcharge/+/firmware-cyan-7287.57.B/src/board/cyan/board.c

I'm narrowing down specifically on the I2S interface (SSP2). The Linux driver doesn't seem to ioremap or touch these control registers.

https://chromium.googlesource.com/chromiumos/platform/depthcharge/+/firmware-cyan-7287.57.B/src/drivers/bus/i2s/braswell/braswell.c

My theory is that for the MAX98090 codec on Braswell, the SSP2 interface needs to be initialized. I'll try to modify the driver to do the initialization... My experience is with ARM platforms, not Intel, so I'll see how far I can get.

plbossart commented 7 years ago

The ACPI-related code does all the initialization of I2C (and the interaction with the maxim codec works fine), the SSP is configured by the audio firmware. I suggest you don't waste too much time on this. The only assumption which was made is that the clock is managed by the BIOS/Coreboot, if this was not correct then this would explain why there is no sound. Ideally we'd need to figure out how to enable a loopback inside of the maxim codec to see if the SSP connection works. I haven't had time to look into this but that's how we debugged other platforms.

  1. prove that the digital audio transfers work across the SSP link with a loopback
  2. do an analog loopback from mic to speakers to prove than the audio subsystem is not blown
  3. try digital to analog.
jeffkub commented 7 years ago

The MAX98090 driver appears to have the loopback bit LBEN already supported. My understanding of the driver and ALSA subsystem is that I can set this bit with the following commands.

amixer -c2 set 'LBENL Mux' 'Loopback'
amixer -c2 set 'LBENR Mux' 'Loopback'

However, when I play some audio, I'm seeing activity in pulse audio on the output channel but not the input channel. If the loopback was working, I was expecting to see activity on the input channel. I may be missing something...

I also added some code to print the SSP2 registers in the intel-sst-acpi driver

I can't find any documentation on the LPE or the SSP peripherals on the Braswell chip. However, from looking at the depthcharge code, bit 7 of the SSCR0 register is the SSP enable bit, which is read as 0. Though, it may be that this is early in the driver init before the audio firmware sets up the SSP2...

Update: After receiving the firmware init message, I'm seeing the regs change. It looks like the audio firmware is setting up the SSP2

plbossart commented 7 years ago

It could also be a recent bug that was discussed recently where settings up the clocks mucks with what the Coreboot firmware did. See https://www.spinics.net/lists/linux-clk/msg18650.html

jeffkub commented 7 years ago

Great news! I was able to get audio output through the speakers by mucking around with the alsamixer settings. It appears to have been a configuration issue.

I'll try to figure out what settings I changed and update here.

jeffkub commented 7 years ago

I have the speakers, headphone jack output, and built-in microphone working. The only bit not working yet is the headphone jack mic.

I modified the galliumos 4.12.0 kernel with the following patch, based on the findings here https://bugzilla.kernel.org/show_bug.cgi?id=151521

cyan-audio-driver-fix.patch.txt

I also used the ucm configuration files from the chromeos repo

https://chromium.googlesource.com/chromiumos/third_party/adhd/+/master/ucm-config/cyan/chtmax98090

with some modifications, as shown in this patch

ucm-mod-to-enable-audio.patch.txt

and placed the files at /usr/share/alsa/ucm/chtmax98090/. I can then reboot my computer and the settings persist.

Glad to finally have working audio on my chromebook 😄

ryanpcmcquen commented 7 years ago

@jeffkub, does that mean audio will soon work with GalliumOS on CYAN?

jeffkub commented 7 years ago

@ryanpcmcquen I'm not an active developer on the GalliumOS project, so I can't say if and when these changes will make it to release. That will be up to the distro maintainers.

lenlo commented 7 years ago

That's great @jeffkub! Thanks a ton for your sleuthing. Have you submitted your changes back to the GalliumOS project? I couldn't find your fork, but I'd love to try out your fixes. Would you be willing to make your precompiled custom kernel available for direct downloading until it's released? No warranties, of course. Cheers!

reynhout commented 7 years ago

@jeffkub Excellent, thanks for all of this work! I will try to repro today on the new 4.12 kernel and hopefully have something packaged up soon after.

plbossart commented 7 years ago

This is good progress, however I am confused on the fixes.

jeffkub commented 7 years ago

@plbossart the driver changes came from this bug on the Kernel.org bugzilla site. I specifically used the ACPI support, Fix I2S configs and remove useless code, and solve NULL dereference patches. All three look like patches that you had created back in February.

Here are the complete UCM files with my modifications

chtmax98090.conf HiFi.conf

plbossart commented 7 years ago

pretty funny, i didn't even remember my own patches. Gah. I'll give it a try on my cyan device, thanks.

friedman101 commented 7 years ago

Thanks for working on this guys, I'm looking forward to having working audio on my cyan :+1:

plbossart commented 7 years ago

The UCM config looks fine, the only weird thing is the reference to 'Ext HP Switch' which should really be replaced by 'Headphone Switch' My cyan device seems to be dead so unfortunately I couldn't test my cleaned-up patches. If someone was willing to test my branch it'd be a good thing. https://github.com/plbossart/sound/commits/topic/cyan

We may be able to use the same machine driver for rambi, but same thing my test device is fried as well.

Bloomca commented 7 years ago

I would like to help, but unfortunately I have zero idea how to test it. Maybe you can point out to me, where can I start in order to apply your patches on my CYAN device?

Thanks!

plbossart commented 7 years ago

if it helps I can provide this set of patches rebased on the regular gallium OS (need git remote information), it's no big deal. You would just need to recompile.

reynhout commented 7 years ago

@plbossart Thanks so much for your help! I'm excited to get this working on our CYAN test device. I had hoped to work on it yesterday, but it now looks like late today or tomorrow -- in any event, as soon as I get a couple hours to pull it all together and build some kernels, we should have packages available for testing.

@Bloomca I think two of the three patches are already in the repo (on the 4.10.5 branch, I think). The missing patch fixes the null deref error, which should be the last piece required. I'm going to apply all of them to the 4.12 branch, and (unless there are unresolvable issues) will push the kernel pkg to the testing APT repo. If you make a build before we can get the pkg pushed, let us know how if you run into any issues!

How to test those patches (how I did it) is:

For me, I still can't get any sound, but it's better than ever. The sound card is recognized. alsamixer show some controls. I can play sound and I see in pavucontrol the audio level moving with the sound I am playing. Mic doesn't work either. Note: the sound hardware is working because I still get beeps when I boot and I fail to select the legacy boot right away.

edit: this is basically a rewrite of https://github.com/GalliumOS/galliumos-distro/issues/317#issuecomment-322658720

@jeffkub how did you tweak the alsa mixer to make it work, do you remember? Could you share your /var/lib/alsa/asound.state ? I believe that's where alsa stores its internal state.

plbossart commented 7 years ago

Just to be clear, the patches I have on my tree are different. I scrapped my initial null reference patches to use the cleaner ones posted on alsa-devel (but never merged somehow).

Velyro commented 7 years ago

@reynhout do you know exactly when the new kernels will be available for download?

@mildred ahah, I was trying to figure out where that file was. I've noticed that some ALSA settings were persistent across reboots; for a while i had my config messed up to the point that the LPE firmware was returning errors.

I've noticed that not all ALSA settings are in the UCM file... I suspect that those missing would be persistent across reboots. Most likely I have a persistent setting that makes the audio work.

I'll provide my asound.state file when I have access to my CYAN device this evening.

jeffkub commented 7 years ago

@mildred here is my asound.state file

I've found it useful to do a amixer -c2 > amixer.txt to dump all settings specific to the chtmax98090 device. You can do a diff to see what settings have changed. Here is my working configuration

amixer.txt

Unfortunately, I've messed with so many settings that I can't remember exactly what I did.

mildred commented 7 years ago

It just works! Thanks a million. To restore the settings from this state file just run sudo alsactl -f downloaded/asound.state.txt restore 1 where 1 is the card number. The same you can pass to amixer -c1 to see the settings.

For me the chtmax98090 device is the card 1, 0 being the HDMI sound device.

mildred commented 7 years ago

The most meaningful settings that appear changed seem to be:

Note: headphone detection is not working, perhaps due to this last setting.

Here is my asound.state which was probably saved when sound was not working still and the diff asound.state.diff which shows the difference with the working asound.state.

I suppose that booting the machine with the asound.state missing from /var/lib/alsa (be careful that when you shut down the computer, the file is going to be rewritten), it should have default settings.

jeffkub commented 7 years ago

@mildred I was able to reset my alsa settings by following this and deleting the ~/.config/pulse directory. I noticed that the default config had selected the headphone port as the output. I was able to switch to speakers in the audio settings.

reynhout commented 7 years ago

Audio is now working on our CYAN test device! Thanks to everyone for help on this ticket, we are making progress toward a public release. Please help test the new packages on your CYAN!

Updated packages are in the galliumos-testing repository for now. To enable, see https://wiki.galliumos.org/Repositories.

Relevant packages are:

ii  galliumos-braswell           2.0.6             all          GalliumOS Braswell customizations
ii  linux-image-4.12.0-galliumos 4.12.0-galliumos4 amd64        Linux kernel, version 4.12.0-galliumos

Notes, and questions

I ended up keeping the 'Ext HP Switch' labels in chtmax98090.conf, to suppress some ALSA complaints about the device names at startup.

I added some logic in /etc/pulse/default.pa to select the sink and source properly on different Chromebooks. The .ifexists flow control meta command only works on filenames or module names, so I ended up using a sysfs entry for each codec: https://github.com/GalliumOS/galliumos-braswell/blob/82d26eea721f6f643450f3fba5ea3e1d2e0c2e80/etc/pulse/default.pa#L179, e.g.:

.ifexists /sys/devices/platform/808622A8:00/cht-bsw-max98090

This works, but feels like the wrong way to do it. Is there a better way?

Relevant logfile excerpts, and more questions

The "ASoC: no DMI vendor name!" is caused by a missing mapping between the ID and a text label, right?

Thank you! Tested with CYAN - internal speakers working, headphone jack working (no detection, manually switched output device) the internal microphone does not seem to be working though

SanzSeraph commented 7 years ago

Tested with CYAN. Internal speakers are working!

vb216 commented 7 years ago

Great stuff! Updated to galliumos-testing, worked straight out of the box for me

Thanks!!

Just did a quick install and internal speakers worked. Headphones didn't. My Sennheiser USB-Headset was detected as sink but didn't play any audio instead the speaker stayed on. Will do further testing.
