RaspberryPi-GPIO-Audio

Audio DAC interfaced through Raspberry Pi GPIO such as i2s and also two fan-cooled Raspberry Pi 4B 3d-printed cases with two different audio DAC hats.

WM8960 Wolfson Audio DAC

Waveshare WM8960 Play/Record Audio Hat with a Wiki and a Github repository.

It is also used in the Minidexed Synth.

An ALSA capabilities script indicates this DAC to perform up to 32bit audio resolution at a 384kHZ sampling rate - see alsa-capabilties card 4.


### Instructions for Pi5 with kernel 6.1.0-rpi7-rpi-2712 (2024) To **enable the WM8960 Waveshare hat with the Raspberry Pi 5** the following is required:
Refer to the [**solved issue here**](https://github.com/waveshare/WM8960-Audio-HAT/issues/51), and then use the [**script here to install**](https://github.com/ubopod/ubo-sdk/blob/main/system/setup/install_wm8960.sh). Also see the [**build here**](https://github.com/TobiasVanDyk/Raspberry-Pi-PC-PSU-Desktop-Computer-with-a-Hard-Disk-Drive-and-Fan-and-Switch).

### Instructions for kernel 6.1.19.xx (2023) Currently (March 2023) the default update for the 32bit install of RPi OS boots the 64bit kernel after the update to 6.1.19 - change that to boot the 32bit kernel by adding arm_64bit=0 to /boot/config.txt, and check with uname -a -> Linux raspberrypi 6.1.19-v7l+ #1637 SMP Tue Mar 14 11:07:55 GMT 2023 armv7l GNU/Linux. It is therefore advisable to use the 64bit Raspi OS - see [**Install-x64-WM8960**](https://github.com/TobiasVanDyk/RaspberryPi-GPIO-Audio/blob/master/WaveshareMarch2023/Install-x64-WM8960.txt) for the driver install results. **Install - Use the new March 2023 Waveshare Drivers:** ``` 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. ### Instructions for kernel 5.15.xx (2022) Currently (May 2022) there are two different ways to install the wm8960 soundcard on the new 5.15 kernel - both methods work well with pulseaudio and/or alsa. For a combination of the waveshare (Dr-Ni April version) and seeed drivers (HinTak version) refer to [**this posting**](https://github.com/waveshare/WM8960-Audio-HAT/issues/44#issuecomment-1113349654). This combo method was tried and also yields a noise-free functional pulseaudio and alsa wm8960 sound device - refer to [**install-combo**](install-combo.txt) for the details of the installation. *It is advisable to power-cycle the Raspberry Pi after installation of the sound driver - a reboot may not be enough.* **Install 1 - Use the new 1 May 2022 Waveshare Drivers:** ``` 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. If present, ignore the message "failed to load i2s-mmap" - it does load from config.txt and it is required. **Install 2 - Install using the [Seeed Voicecard](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT.html) Drivers** To [**install**](https://github.com/HinTak/seeed-voicecard) first uninstall the waveshare WM8960 driver and reboot then delete the old WM8960-Audio-HAT folder. (It is better to remove power from the Raspberry Pi and HAT completely before installing these drivers.) For more details about this HAT look [**here**](https://github.com/TobiasVanDyk/RaspberryPi-GPIO-Audio/tree/master/ReSpeaker2MicsPiHAT) or [**here**](https://www.seeedstudio.com/ReSpeaker-2-Mics-Pi-HAT.html). This driver also works without any adjustments to audio settings (i.e. works with both pulseaudio and alsa without distortion or noise). ``` git clone https://github.com/HinTak/seeed-voicecard cd seeed-voicecard sudo ./install.sh sudo reboot ``` **This seeed install also [works](64bit-kernel-515xx/) on the 64bit kernel-5,15.xx. You may want to change kernel.img to kernel8.img in the install.sh but it is not necessary.** If you use headphones as the primary output, use pavucontrol (sudo apt install pavucontrol), run it then and select wm8960-headphones instead of the wm8960-speaker, and adjust the neadphone volume to above 0. This will make the headphone level sticky. For the troubleshooting with an alsa-only settings, see the screenshot below [**First to Eleven's cover of Boulevard of Broken Dreams by Green Day**](https://www.youtube.com/watch?v=ilLTcTXTI0E)


### Instructions for kernel 5.10.xx (2021) If the wm8960 waveshare driver is already installed then uninstall it before updating the kernel to 5.10.11: ``` cd WM8960-Audio-HAT sudo ./uninstall.sh sudo reboot ``` Update to the new kernel, reboot and then delete the user folder WM8960-Audio-HAT if it exists. After the github clone as below, but before doing the install, [**download the modified wm8960.c**](https://github.com/Sybility/WM8960-Audio-HAT) from the Sybility WM8960-Audio-HAT github, and use as a replacement for the same file in the new WM8960-Audio-HAT folder. For more information about this file read about the wm8960 kernel 5.10 issues [**here**](https://github.com/waveshare/WM8960-Audio-HAT/issues/24) and [**here**](https://github.com/waveshare/WM8960-Audio-HAT/issues/23). The modified [**wm8960.c**](wm8960.c) has also been copied to this github. ``` git clone https://github.com/waveshare/WM8960-Audio-HAT cd WM8960-Audio-HAT sudo ./install.sh sudo reboot ``` Run alsamixer, press F6, select wm8960 audio, and check that the headphone volume is not 0 (if you are using that instead of the speaker output). **64bit kernel 5.10.11** Starting with the Aug 2020 Raspi OS 64 bit, which was then updated to kernel 5.10.11.v8+ (sudo apt full-upgrade), it also yielded a fully working WM8960 HAT using the compile method as above. All the configuration files and overlays are in the 64bit folder.


### Instructions for kernel 5.4.xx (2020) **Method A:** Start with last released raspios install image 2020-05-27-raspios-buster-full-armhf.img, then update it fully: sudo apt-get update, sudo apt-get upgrade -y, or whatever method you are used to. You will then end with a 5.45x kernel. Then do Step 1 and 2. **Method B:** Start with last released raspios install image 2020-05-27-raspios-buster-full-armhf.img, then do Step 1 which will do a kernel upgrade as well. Use Step 2 to check if the WM8960 driver is installed, if not repeat Step 1 without a cleanup or uninstall - i.e start with sudo ./install.sh. Reboot and check again. I had to do this twice for one of the installs - refer to this [**issue**](https://github.com/waveshare/WM8960-Audio-HAT/issues/10). **Step 1:** ``` git clone https://github.com/waveshare/WM8960-Audio-HAT cd WM8960-Audio-HAT sudo ./install.sh sudo reboot ``` **Step 2:** After reboot check if audio device has been installed with aplay -l, which should list the wm8960 device as card 1 or 2. You can then follow the instructions at the [**Sparkfun WM8960 setup for alsa**](https://learn.sparkfun.com/tutorials/sparkfun-top-phat-hookup-guide/wm8690-audio-codec). ``` sudo alsamixer sudo nano /usr/share/alsa/alsa.conf sudo alsamixer ``` The result is something like shown below - remember to select the wm8960 audio device and mixer in vlcplayer (or audacious) and either the headphone or speaker as the mixer element.
