Build error on kernel: 5.15.30-v7+ (armv7l)

[theNorNi]

New kernel version for Raspberry OS Bullseye raspberrypi-kernel (1:1.20220328-1). raspberrypi-kernel-headers (1:1.20220328-1).

Build fails with error message: "Error! Bad return status for module build on kernel: 5.15.30-v7+ (armv7l)" make.log

[bnwlf]

Same here at waveshares 13.1 Magic Mirror with Raspberry OS Bullseye.

[dr-ni]

I've started to fix the problem: (see also https://github.com/torvalds/linux/blob/master/sound/soc/generic/simple-card.c)

Compilation is now working in my fork: diff: https://github.com/dr-ni/WM8960-Audio-HAT/commit/ae4522f44125754783ce12043bc0f3ffab075441

However, still some remainining problems:

I have now some noisy sound on raspberrypi zero 2. Can anybody test this also on other models and report?

https://github.com/dr-ni/WM8960-Audio-HAT

[TobiasVanDyk]

Yes thank you - tested on Pi4B waveshare Pi WM8960 Hat- git pull from your own fork - scratchy sound with VLC - but it is getting there!

[dr-ni]

and recording? is it working?

[TobiasVanDyk]

yes tested with arecord -v test.wav is working

[TobiasVanDyk]

speaker-test -t wav

gives me a clear "Front-Left" with no scratchy noises

[dr-ni]

and speaker-test -t wav -c 2

is the recording stereo and scratching?

[TobiasVanDyk]

speaker-test -t wav -c 2 Front-Right no scrathes very clear hifi

recording mike is inside a box on the hat but is sounds clear no scratches

[TobiasVanDyk]

speaker-test -t wav -c 2 Front-Right no scratches very clear hifi

recording mike is inside a box on the hat but is sounds clear no scratches

[dr-ni]

is it stereo?

[TobiasVanDyk]

speaker test -t wav -c 2 reports it as 2 channels arecord is mono

[dr-ni]

and arecord -f S32_LE -r 48000 -c 2 test.wav

[TobiasVanDyk]

Stereo

[dr-ni]

can you please test again:

git pull git checkout master sudo ./install.sh sudo reboot

[TobiasVanDyk]

Hi still crackling playback with vlc mp3 Goimg to do clean uninstall - install

[TobiasVanDyk]

Plays nicely with the wav files in /usr/share/sounds - no scratches

But 16bit 44.1kHz wav file still scratchy sounds

[dr-ni]

what does aplay -l and aplay -L show?

when using audacious getting much better quality sound - have to adjust the two volume (audacious and main) controls - still some background crackle but much less

Getting no crackle sound in Audacious when using Alsa with direct HW WM8960 setting - solved?

Yes using the same setting with VLC (ALSA and Direct HW WM8960) gives good sound - SOLVED by your code!!

[bnwlf]

Hi folks, I hadn't the time to check the new fixes. Since my post i found this repo: https://github.com/HinTak/seeed-voicecard. It works at least somehow. (But I will try it in the next days. Thanks for that!)

The wm8960-soundcard.service is there also failing (status 99). Do you know the sense of this service since the driver?

[dr-ni]

@TobiasVanDyk is aplay -D dmixed pcm16LE44100.wav playing clean?

[dr-ni]

@bnwlf sorry I'm not familar with this

[TobiasVanDyk]

@dr-ni

Yes it plays clean no noise - I used another 16bit/44.1kHz file: (no dmix plugin so it plays little bit too fast 48/44.1 x normal rate)

pi@raspberrypi:~ $ aplay -D dmixed pcm16LE44100.wav pcm16LE44100.wav: No such file or directory pi@raspberrypi:~ $ aplay -D dmixed 1.wav Playing WAVE '1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Warning: rate is not accurate (requested = 44100Hz, got = 48000Hz) please, try the plug plugin (-Dplug:dmixed)

VLC now plays cleanly using ALSA + wm8960-soundcard-direct-mixer setting in VLC preferences->Audio-settings Using pulseaudio still has the noisy distortion

To install first uninstall the old waveshare driver and reboot then delete the old WM8960-Audio-HAT folder Then: git clone https://github.com/dr-ni/WM8960-Audio-HAT cd WM8960-Audio-HAT sudo ./install.sh sudo reboot

Ignore the message "failed to load i2s-mmap" - it does load from config.txt and it is required Change VLC audio preferences to use ALSA and the mixer to wm8960 direct mixer

[dr-ni]

I have actually no clue about that noise is it only with pulseaudio?

you have to play like this: aplay -D plug:dmixed audio.wav

[TobiasVanDyk]

I assumed it is the same noise you experienced here?

dr-ni commented 23 hours ago update: https://github.com/dr-ni/WM8960-Audio-HAT/commit/4ec150d5a0042727143e3b910b99dd56a3a8011b I have now some noisy sound on raspberrypi zero 2. Can anybody test this also on other models and report? https://github.com/dr-ni/WM8960-Audio-HAT

[dr-ni]

I have now no noise with dmixed so maybe only a resampling problem. I don't have pulseaudio and no X

[TobiasVanDyk]

Yes I am happy - it now plays nicely I am hoping for others to comment on their experience?

The noise seems to be a distorted audio sub-level with clear audio super-imposed on the noise

[dr-ni]

yes, would be interesting how it is working on other systems

https://github.com/dr-ni/WM8960-Audio-HAT

[dr-ni]

I've now also tested https://github.com/HinTak/seeed-voicecard It is working very well

@TobiasVanDyk do you have the noise with this driver?

[TobiasVanDyk]

I tried to but it does not like my WM8960 waveshare hat: https://www.waveshare.com/wm8960-audio-hat.htm

dmesg | grep wm8960 [ 17.295029] wm8960 1-001a: ASoC: error at snd_soc_dai_hw_params on wm8960-hifi: -22 [ 17.295045] bcm2835-i2s-wm8960-hifi: ASoC: soc_pcm_hw_params() failed (-22) [ 17.295750] wm8960 1-001a: failed to configure clock

I think it either needs a custom kernel and/or a Seeed HAT and/or changed install.sh I attach the install.log install3.txt

[dr-ni]

can you uninstall your WM8960-Audio-HAT (sudo ./uninstall.sh) then cd seeed-voicecard make clean make and send me the output?

[TobiasVanDyk]

Hi dr-ni

make1.txt

[TobiasVanDyk]

Ok I made a mistake - when I did the git clone from HinTak then the drivers works first time - no need to put it into ALSA make2.txt

[dr-ni]

ok so my fork is still with errors...

[TobiasVanDyk]

Yes sorry about the mistake I made....

[bnwlf]

Hi @dr-ni i had some time to test your driver,..

• compliation without errors
• recording with arecored is working
• aplay the on the recorded file causes a scratch noise and causes then an instand reboot.

If I think a bit longer I tested the seeed driver first,.. maybe there are some issues with the old installation,.. I will check that.

so I would say its close,.. Thanks for your work.

[bnwlf]

Success,.. new install helped!

[bringItUpX]

Big Thanks @dr-ni for your work. Now i can use the module in the Raspi Desktop although i use the newer dtoverlay=vc4-kms-v3d in the config.txt. And this without noise. I wish to sum up all steps: I uninstalled the unworking WM8960-Audio-HAT from WAVESHARE and deleted the files that i downloaded from the WAVESHARE repo. I made git clone https://github.com/dr-ni/WM8960-Audio-HAT in my user directory of my Raspi 4 (32bit Desktop), (attatched with the WM8960 audio module and two speakers and a 7 inch touch display). cd WM8960-Audio-HAT sudo ./install.sh sudo reboot

Ignore the message "failed to load i2s-mmap" as @TobiasVanDyk mentined. Then, in the grafical desktop of the raspi you make a rigth click on the speaker symbol and select the wm8960-soundcard. After this you can open Chromium and play a youtube video. You will hear the music, but with some noise.

The next steps will install other drivers for the wm8960-soundcard. Only a new driver, the rest should come from the repo of @dr-ni and stay.

First i run cd WM8960-Audio-HAT and sudo ./uninstall.sh to uninstall the driver from @dr-ni . Then cd .. and git clone https://github.com/HinTak/seeed-voicecard cd seeed-voicecard make clean make sudo ./install.sh

The install.sh script above shows some errors in the midle of working. You need to reboot and run it again.

Then the necessary drivers are installed. Now you can run the install.sh from @dr-ni again, but before i changed this script a little bit. I opened WM8960-Audio-HAT/install.sh and changed this line: install_module "./" "wm8960-soundcard" to #install_module "./" "wm8960-soundcard"

Then run again the install script: cd WM8960-Audio-HAT sudo ./install.sh

I think a cold boot is necessary. Finish! Now you can open Chromium in Raspi Desktop and hear a youtube video without additional noise. Thanks to above two repos. Thanks @dr-ni .

[TobiasVanDyk]

Using the new 1 May 2022 Waveshare Drivers works perfectly:

git clone https://github.com/waveshare/WM8960-Audio-HAT cd WM8960-Audio-HAT sudo ./install.sh sudo reboot

After the reboot aplay -l should show the wm8960 soundcard and plays pulseaudio and alsa with no distortion
