 While the upstream wm8960 codec is not currently supported by current Pi kernel builds, upstream wm8960 has some bugs, we had fixed it. we must it build manually.

 ## 6-Mics Circular Array Kit

 The 6 Mics Circular Array Kit uses ac108 x 2 / ac101 x 1 / micphones x 6, includes 8 ADCs and 2 DACs.
 The driver is implemented with 8 input channels & 8 output channels.
 >**The first 6 input channel are MIC recording data,  
 the rest 2 input channel are echo channel of playback  
 The first 2 output channel are playing data, the rest 6 output channel are dummy**
 Check that the sound card name matches the source code seeed-voicecard.

 ## 4-Mics Linear Array Kit
 [![](https://user-images.githubusercontent.com/3901856/37194106-a0ccebce-23a7-11e8-88c5-ec611e44ec49.png)]()
 In contrast to 6-Mics Circular Array Kit for Raspberry Pi,
 the difference is only first 4 input channels are valid capture data.
 ### Usage:
 ```bash
 #for ReSpeaker 2-mic
 #It will capture sound an playback on hw:1
 arecord -f cd -Dhw:1 | aplay -Dhw:1
 ```
 ```bash
 #for ReSpeaker 4-mic
 #It will capture sound on AC108 and save as a.wav
 arecord -Dac108 -f S32_LE -r 16000 -c 4 a.wav
 ```
 ```bash
 #for 6-Mics Circular Array Kit and 4-Mics Linear Array Kit
 #It will capture sound on AC108 and save as a.wav
 arecord -Dac108 -f S32_LE -r 16000 -c 8 a.wav
 #Take care of that the captured mic audio is on the first 6 channels
 #It will play a mono channel sound file mono_to_play.wav
 #The file to play must be mono channel or else the speaker output nothing.
 aplay -D plughw:1,0 mono_to_play.wav
 #Doing capture && playback the same time
 arecord -D hw:1,0 -f S32_LE -r 16000 -c 8 to_be_record.wav &
 #mono_to_play.wav is a mono channel wave file to play
 aplay -D plughw:1,0 -r 16000 mono_to_play.wav
 ```
 **Note: Limit for developer using 6-Mics Circular Array Kit(or 4-Mics Linear Array Kit) doing capture & playback the same time:  
 1. capture must be start first, or else the capture channels will possibly be disorder.  
 2. playback output channels must fill with 8 same channels data or 4 same stereo channels data, or else the speaker or headphone will output nothing possibly.**

 For hardware testing purposes we made a Rasperry Pi OS 5.10.17-v7l+ 32-bit image with reSpeaker drivers pre-installed, which you can download by clicking on [this link](https://files.seeedstudio.com/linux/Raspberry%20Pi%204%20reSpeaker/2021-05-07-raspios-buster-armhf-lite-respeaker.img.xz).
 We provide official support for using reSpeaker with the following OS:
 - 32-bit Raspberry Pi OS
 - 64-bit Raspberry Pi OS
 And following hardware platforms:
 - Raspberry Pi 3 (all models), Raspberry Pi 4 (all models)
 Anything beyond the scope of official support is considered to be community supported. Support for other OS/hardware platforms can be added, provided MOQ requirements can be met. 
 If you have a technical problem when using reSpeaker with one of the officially supported platforms/OS, feel free to create an issue on Github. For general questions or suggestions, please use [Seeed forum](https://forum.seeedstudio.com/c/products/respeaker/15). 
 When you encounter any installation and use problems when you start your ReSpeaker Pi hat, please use the following image for testing. We have installed seeed-voicecard based on the latest PI image, which can be used by burning it directly on SD. If this still cannot solve your problem, you can ask in the issue. We will try our best to solve your problem.

Hin-Tak Leung	f4cc5722d0	relocating fixed-clock entry, based on upstream advice See upstream - https://github.com/raspberrypi/documentation/issues/1671 https://github.com/raspberrypi/documentation/pull/1673 Quoted here: * Only Device Tree nodes at the top level of the tree and children of a bus node will be probed. For nodes added at run-time there is the further limitation that the bus must register for notifications of the addition and removal of children. However, there are exceptions that break this rule and cause confusion: the kernel explicitly scans the entire tree for some device types - clocks and interrupt controller being the two main ones - in order to (for clocks) initialise them early and/or (for interrupt controllers) in a particular order. This search mechanism only happens during booting and so doesn't work for nodes added by an overlay at run-time. It is therefore recommended for overlays to place fixed-clock nodes in the root of the tree unless it is guaranteed that the overlay will not be used at run-time.	2020-12-02 15:30:31 +00:00
