Allo Boss 2 device tree overlay or driver broken

[MichaIng]

Describe the bug

We have several reports across multiple forums that the Allo Boss 2 dtb is not working (well) after one of the recent kernel upgrades: https://github.com/raspberrypi/linux/blob/rpi-6.1.y/arch/arm/boot/dts/overlays/allo-boss2-dac-audio-overlay.dts

• https://audiophilestyle.com/forums/topic/67938-no-sound-output-from-allo-boss-2/
• https://dietpi.com/forum/t/allo-boss-2-does-not-output-sound-after-update-to-dietpi-8-15-8-16/16594
• https://community.roonlabs.com/t/update-to-8-18-2-completley-broke-my-system/244575
• https://forums.raspberrypi.com/viewtopic.php?t=350656

I am not sure who is responsible, Allo, RPi kernel repo, RPi firmware repo, no one? I had a look into it but could not see any obvious error, like false node or such in the dtb. Since it affects quite a lot of users for 2 months without any other solution than downgrading the kernel, I thought it cannot hurt to report it here and hope for the best 🙂.

Steps to reproduce the behaviour

Use Allo Boss 2 HAT, enable related overlay, play audio, which either plays nothing or highly distorted, depending on audio source and format.

Device (s)

Raspberry Pi 4 Mod. B

System

It affects RPi OS, DietPi, moOde, i.e. all distros which use these kernel sources v6.1.

Additional context

No response

[pelwell]

I don't have one of these devices, and no other sound cards appear to use the cs43130 codec, so debugging will be slow.

Any thoughts, @babuenir?

[MichaIng]

Me neither. But if someone has an idea how to debug/which output/logs to check, I will try to get everyone here from the other forums and/or forward/collect infos.

[pelwell]

Let's assume for now that the main codec driver is OK, since it is an unmodified upstream file. The overlay is extremely simple and hasn't changed since 5.15, so we can ignore that, which leaves the soundcard driver - sound/soc/bcm/allo-boss2-dac.c.
We can start to enable tracing in that driver, but before that we can capture the i2c traffic in the two kernels and compare them.

1. Clear the kernel message log:

$ sudo dmesg -C

2. Enable i2c tracing:

$ sudo sh -c "echo 1 >/sys/kernel/debug/tracing/events/i2c/enable"

3. Attempt to play a sound. You can use speaker-test, but turn the volume down first. On RPiOS (and perhaps others) you can also use aplay /usr/share/sounds/alsa/Front_Center.wav.

4. Capture the tracing output:

$ sudo cat /sys/kernel/debug/tracing/trace > i2c_log1.txt

5. If you want to run another test without rebooting, first clear the trace so far:

$ sudo sh -c "echo >/sys/kernel/debug/tracing/trace"

Run that test on both kernels, capturing the log to a different (and ideally suitably named) file each time.

If the playback doesn't appear to work, report what you observe, and the output of dmesg.

Good day, thank you for the help on this issue.

Firsts tests have been run on a vanilla raspberry pi os 64 bit lite install combined with enabling the allo-boss2-dac-audio overlay / driver. Apt update/upgrade has been ran in addition.

Kernel version:

Linux raspberrypi 6.1.21-v8+ #1642 SMP PREEMPT Mon Apr  3 17:24:16 BST 2023 aarch64 GNU/Linux

Output of the i2c traces as attached:
i2c_log_speaker_test_kernel6_1_21.txt
i2c_log_wav_kernel6_1_21.txt

After playback there was no output of dmesg whatsoever.

Same thing but for the older kernel Linux AlloPi 5.15.84-v8+ #1613 SMP PREEMPT Thu Jan 5 12:03:08 GMT 2023 aarch64 GNU/Linux on diet-pi; gives the following when running aplay /usr/share/sounds/alsa/Front_Center.wav:

Playing WAVE '/usr/share/sounds/alsa/Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1349: Channels count non available

This is probably also the reason aplay isn't captured in that particular log.

i2c_log_speaker_test_kernel5_15_84.txt
i2c_log_wav_kernel5_15_84.txt

In general the output of tracing the speaker test command seems quite comparable.

Thank you for your guidance.

EDIT: maybe worthwhile to mention here: after enabling the tracing, the speaker-test command in the old kernel 5.15.84 seemed to progress significantly slower than normal. This was not observed (not in this detail) for the new kernel 6.1.21

**this is a condensed copy of a post that i put in the dietpi forums moments ago.

[MichaIng]

The channel count error is btw expected with audio source formats which are not natively supported by the sound driver/card. You can enforce 2 channels with aplay -c 2 /path/to/some.wav resp. speaker-test -c 2. And when you enable the ALSA auto-conversion/plug plugin, it is converted automatically. This can also be done in dietpi-config.

However this is unrelated to the Boss 2 driver issue.

[pelwell]

There are differences between the traces associated with the two kernels (aside from the i2c spam from some python script), but nothing that screams error. Somebody who actually has one of these things and who cares more than the manufacturer is going to have to do some diagnosis.

[MichaIng]

Pinging the manufacturer here, @alloboss2 in case you are not aware yet.

[moodeaudio]

I could do some tests
Boss 2 kernel 6.1.21 all indications are that playback is working but no sound output.

Btw, their Katana driver also has issue but it's a driver load fail just on a Pi 4B, other Pi's are OK.

I think the cs43130 problem is due to this commit: e14bd35

It switches from describing a fraction with two separate u16s linked only by name and usage to using a standard u16_fract structure. Unfortunately the author and reviewer failed to notice that the conversion effectively swapped the numerator and denominator.

#5510 is a potential fix - I'm happy that it fixes the numerator/denominator ordering, but there might be other issues as well. Once the autobuilds have completed (in about an hour from now) you will be able to install a test kernel using sudo rpi-update pulls/5510.

[pelwell]

It's good to go, if anyone wants to try:

$ sudo rpi-update pulls/5510

And if you don't have rpi-update:

$ sudo curl -L --output /usr/bin/rpi-update https://github.com/raw/raspberrypi/rpi-update/master/rpi-update && sudo chmod +x /usr/bin/rpi-update

[moodeaudio]

One of our users confirmed the patch works.
https://moodeaudio.org/forum/showthread.php?tid=5644&pid=47286#pid47286

[pelwell]

Excellent. The patch was merged yesterday, so it will be in future kernel releases.

At some point I'll have to notify the upstream devs...

[moodeaudio]

Super nice!

Boss 2 is beloved by many Pi audio enthusiasts.

The patch is now queued up for Linux 6.4: https://kernel.googlesource.com/pub/scm/linux/kernel/git/broonie/sound/+/a9e7c964cea4fb1541cc81a11d1b2fd135f4cf38
Because it has a Fixes: tag it should be back-ported to LTS kernels (i.e. 6.1) as a matter of course, at which point we'll drop our downstream version.
