请教关于F1C100S的声卡使用speaker-test播放无声音问题

使用的linux6.1.54版本内核,移植论坛大佬提供的驱动。

目前现象是驱动加载后引脚上能有1.5V电压,声卡也能正常的显示出来。

内核启动时有以下输出:

[    1.191964] ALSA device list:
[    1.195021]   #0: Loopback 1
[    1.197913]   #1: suniv Audio Codec

然后使用speaker-test播放时喇叭只有一个上电的吧嗒声。

在DMA和声卡驱动中加上日志输出,从日志看DMA和声卡都有正常工作。
按理speaker-test播放应该会输出噪音,不知道有没有哪位大佬知道什么情况?

附播放时DMA驱动和声卡驱动日志:

Re: 请教关于F1C100S的声卡使用speaker-test播放无声音问题

已经解决,使用alsamixer把音量设大没有什么用,我以为把音量开启就可以了。

使用tinymix -D 1 contents 发现switch并没有开启。

使用tinymix -D 1 set 2 1开启switch后再使用speaker-test就有噪音输出了。

有内核参考吗?声卡出来了就是一直播放失败,不知道哪里少改还是什么
