Welcome to OpenEmbedded, the build framework for embedded Linux. OpenEmbedded offers a best-in-class cross-compile environment. It allows developers to create a complete Linux Distribution for embedded systems. Some of the OpenEmbedded advantages include:

adopted as the build system for the Yocto Project in March 2011.

support for many hardware architectures

multiple releases for those architectures

tools for speeding up the process of recreating the base after changes have been made

easy to customize

runs on any Linux distribution

cross-compiles 1000's of packages including GTK+, Qt, the X Windows system, Mono, Java, and about anything else you might ever need

step1:
git clone https://gitee.com/yanyitech/openwrt.git cd openwrt ### Quickstart 1. Run `./scripts/feeds update -a` to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default 2. Run `./scripts/feeds install -a` to install symlinks for all obtained packages into package/feeds/ 3. Run `make menuconfig` to select your preferred configuration for the toolchain, target system & firmware packages. 4. Run `make` to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

@jugg 如下图所示，电脑的line out输出经过衰减以后接入COOLPI耳机座的MIC输入端。正常麦克风的电平范围控制到20mv以内。所以电阻参数根据电脑line out输出的信号幅度决定。

@george Thanks for checking. That's really strange. At first I thought the issue was associated with the monitor—some HDMI compatibility glitch—but was able to get the same behavior across three different televisions. I've done it with both the 20230424 and 20230306 Ubuntu 22.04 images as well as the new 23.04 image. I've even installed the image on both the SSD care and the built-in eMMC.

I've also kept syslog and dmesg logs open (on an SSH session) and I'm not seeing any messages that make sense. All I know is that the instant I hit the OK button to log out or restart or shutdown, the screen freezes and the mouse pointer doesn't move. But it doesn't happen with the built-in default "coolpi" account.

If anyone has any theories or ideas of what I might capture to further diagnose, let me know.
