测试shairport-mmap可用.
碰到几个问题:
1.有时候配置之后, 在iphone仍然找不到airport (重启也无效). 重新用sysupgrade刷一遍就可用了.
2.声音出不来. 后来运行了其他播放或录音程序, 就能出声了. 什么道理还搞不明白

我的iphone搜不到板子的airplay. ios版本10.2.1

多谢啦。我先试试看吧。

用Alsa. 已经是mmap方式。如果确定是ctrl+c的原因那就没事了。我测试确实经常要ctrl+c强制退出。

0_1492698310639_openwrt-ramips-mt7688-Widora-squashfs-sysupgrade.bin

运行命令：
cd /tmp
xxzlyl ddd

有时候会崩溃，而且是随机性的崩溃。
