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

dr-ni · 2022-04-06T15:43:41Z

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: dr-ni@ae4522f

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 · 2022-04-07T14:05:33Z

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 · 2022-04-07T14:09:43Z

and recording? is it working?

TobiasVanDyk · 2022-04-07T14:14:13Z

yes tested with arecord -v test.wav is working

TobiasVanDyk · 2022-04-07T14:22:53Z

speaker-test -t wav

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

dr-ni · 2022-04-07T14:27:40Z

and speaker-test -t wav -c 2

is the recording stereo and scratching?

TobiasVanDyk · 2022-04-07T14:31:31Z

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 · 2022-04-07T14:31:39Z

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 · 2022-04-07T14:36:21Z

is it stereo?

TobiasVanDyk · 2022-04-07T14:39:06Z

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

dr-ni · 2022-04-07T14:42:00Z

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

TobiasVanDyk · 2022-04-07T14:44:07Z

Stereo

dr-ni · 2022-04-07T15:23:36Z

can you please test again:

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

TobiasVanDyk · 2022-04-07T15:53:34Z

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

TobiasVanDyk · 2022-04-07T16:13:41Z

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

But 16bit 44.1kHz wav file still scratchy sounds

dr-ni · 2022-04-07T19:14:11Z

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 · 2022-04-07T20:50:13Z

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 · 2022-04-07T21:14:03Z

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

dr-ni · 2022-04-07T21:32:05Z

@bnwlf
sorry I'm not familar with this

TobiasVanDyk · 2022-04-08T06:46:11Z

@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 · 2022-04-08T11:32:15Z

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 · 2022-04-08T11:36:13Z

I assumed it is the same noise you experienced here?

dr-ni commented 23 hours ago
update: dr-ni@4ec150d
I have now some noisy sound on raspberrypi zero 2.

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

dr-ni · 2022-04-08T11:55:23Z

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

TobiasVanDyk · 2022-04-08T12:06:39Z

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 · 2022-04-08T15:06:49Z

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

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

dr-ni · 2022-04-08T19:24:27Z

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 · 2022-04-09T06:18:36Z

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

[ 17.295750] 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

dr-ni · 2022-04-09T11:38:26Z

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

Hi dr-ni

make1.txt

TobiasVanDyk · 2022-04-09T14:34:43Z

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

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.

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 .

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
