把第一个寄存器 [Headphone Playback Volume] 音量设置为 [63], 和第二个寄存器 [Headphone Playback Switch] 设为 [ON]
就可以用 tinyplay播放wav文件了
如何设置这两个寄存器?

设置:
/tmp # ./tinymix set 1 63

我目前遇到的情况是:
用群里提供的根文件可以实现声音播放了 ,我替换掉我自己制作的根文件就是不行。说明内核和设备树都正常了,我感觉是配置文件不对。
tinyalsa 这个软件怎么装进入的呀! 在buildroot 里面没看到呢!

这里有编译过程:小菜鸟又有新问题了, tinyalsa如何编译成arm-linux 静态链接版本
如果搞不定,需要静态链接的二级制文件请举手!
搞定的有点悲剧,我直接改的Makefile
CROSS_COMPILE =arm-linux-gnueabihf-
CC = $(CROSS_COMPILE)gcc
有点暴力的该法。

OK 啦 可以啦 !我明白了。我不能播放的最终原因是因为没有开启耳塞以及音量。别个的根文件就做了这事情的。

@晕哥
晕哥大神,请问下我使用了linux 4.13-y分支的内核,编译成功之后能够挂载u盘,也能够提示有声卡了,但是还是存在一个问题,当我使用移植好的alsa时,
输入命令:aplay 11.wav时,
系统提示:aplay:set_params:1437:not enough memory
这个问题我该怎么解决呢?

@晕哥
晕哥,在进行tinyalsa移植时,具体的移植过程是不是跟alsa库那样要移植对应的文件和文件夹到开发板对应的文件夹中呢?具体我想请教下晕哥这个tinyalsa的移植过程是怎么样呢?
离线
@晕哥
晕哥,我刚才尝试了一下,tinyplay成功了,成功的步骤我总结了一下:
一。tinyplay移植
(1) git clone https://github.com/tinyalsa/tinyalsa.git
(2)把所有Makefile的 CC行都改成这样:
CC = $(CROSS_COMPILE)gcc
(3)把所有Makefile的改为
CROSS_COMPILE = arm-linux-gnueabihf-gcc;
使用的是静态链接,当然前提是要在电脑上安装了 :
arm-linux-gnueabihf-gcc,
安装方法:sudo apt-get install gcc-arm-linux-gnueabihf
(4)在tinyalsa文件内执行make命令
(5)接着在arm板上移植步骤如下:
1.将tinyalsa/utils/下的tinycap tinymix tinypcminfo 和tinyplay 复制到开发板的/bin目录下;
2.将tinyalsa/src下的libtinyalsa.so.1 libtinyalsa.so
libtinyalsa.so.1.1.1拷贝到开发板的/lib即可。
(6)运行tinymix 来调节音量
tinymix set 1 63
tinymix set 2 1
tinymix contents
(7)在这个之前我是已经将alsa移植过一次,不知这个会不会有影响,目前还没有测试过。

@晕哥
晕哥,谢谢指导,确实我配置完uboot里的LCD启动之后,加上内核的配置simple framebuffer之后,再次启动内核,就出现了/dev/fb0了

前面我都uboot传递了480*272的屏幕参数。但是我的内核配置存在问题,所以我之后linux4.13-y使用了默认配置make ARCH=arm licheepi_zero_defconfig,重新编译一次,又神奇的出现了fb0了。

@晕哥
晕哥,请问下是不是如果开发板没有接显示屏的话,执行cat /dev/urandom > /dev/fb0会出现如下的错误的呢?
cat: write error: No space left on device
因为我订购的屏幕暂时还没到货,我是没有接显示屏来执行该语句的,所以想请问下晕哥这是配置出错了还是没有接显示屏引起的呢?

@晕哥,我使用 tinyalsa在linux 4.13-y 分支上已经可以正常播放音乐,耳机也有声音,现在换成bsp的内核,播放wav文件耳机没有声音。结束时打印这个:
# ./tinyplay 78.wav
playing '78.wav': 2 ch, 48000 hz, 16 bit
error playing sample
./tinymix contents的结果如下
