src="https://pan.daliansky.net/d/blog/node_output.png" alt="node_output"><br>通过观察我们会发现,0x14与0x02连接,转换成10进制就是20->2,同样的,0x21与0x03连接,转换成10进制就是33->3,我们把它放到表格中</p><table><thead><tr><th>有效节点</th><th>10进制</th><th>设备名称</th><th>路径</th></tr></thead><tbody><tr><td>0x14</td><td>20</td><td>Speaker

alt="node_input"><br>再来看图片的上半部,最右侧的0x08和0x09是两个声音输入的节点,0x23和0x22是两个混音设备,最前方是设备节点,这个就是输入设备的路径.<br>我的声卡的0x12声音输入路径包括了3个节点;为了便于理解,被我圈起来的红线部分就是0x12(Mic in)的路径(pathmap),8->35->18就是路径,照样还是要将数据放到表格里<br><img

in),我需要将路径找出来,我发现0x19同时连接了两个节点:0x23和0x22,相应地路径为:8->35->25和9->34->25,顺手也把0x1a的路径也整理出来备用,将这两组数据补充进表格里</p><table><thead><tr><th>有效节点</th><th>10进制</th><th>设备名称</th><th>路径</th></tr></thead><tbody><tr><td>0x14</td><td>20</td><td>Speaker

如何新建一个注入id</h1><p>为什么要建立一个全新的layout-id呢?很多时候,我们其实仿冒声卡驱动,只是为了让自己的声卡驱动正常,而通常的做法是找出一个存在的ID,然后整理数据,修改路径和<code>ConfigData</code>,最后编译使用.</p><p>那如果<code>AppleALC</code>的维护者<code>vit9696</code>更新了源代码怎么办呢?你总不能再重复做一遍驱动吧?或者说你好不容易找人帮你做好了一个驱动程序,然后<code>AppleALc</code>就升级了,旧的驱动无法用到新的系统当中,这个时候你的选择是什么?继续找人帮你做驱动?或者自己动手仿冒?</p><p>其实最好的方法是:如果你的声卡不存在于<a href="https://blog.daliansky.net/AppleALC-Supported-codecs.html">AppleALC支持的Codecs列表</a>中,或者其中的某个注入id并不会很好地工作,那么你就需要新建一个注入id编译使用,测试无误后,你甚至还可以将这些修改提交给<code>vit9696</code>,他会将这些更新合并到<code>AppleALC</code>的源代码中,这样以后再有更新你只需要下载个<code>AppleALC</code>的发行版直接使用就好了.<br><img

issue?</a></p><blockquote><p>原引:</p><p>RehabMan对于VrefEn和EPT的部分讨论内容:</p><p>我也尝试了节点0x19的0x20。 这也工作。 所以不知道在我的情况下是否需要VrefEn或EPT。 但是他们与巫毒有关，所以我使用了这个价值。我没有看过Voodoo是否明确地设置了这些值，或者是复位后的状态结果。</p><p>我认为我的设置0xC0到0x21也是没有必要的（仍在试验）。 节点0x19不在任何路径图上，所以我对于如何知道节点需要调整有些困惑。 尽管它在Linux转储中有连接到路径图上的其他节点。 进一步造成神秘，它被描述为Linux转储中的外部麦克风插孔。 为什么麦克风上的控件配置会影响耳机，这是一个谜。</p><p>还要注意，VrefEn和EPT之间有一些奇怪的重叠，这在规范中是不清楚的（它们似乎都使用相同的位）。 例如，将VRefEn设置为001b或010b（50％/地面）将设置标记为“保留”的EPT编码01b / 10b。 它确实说EPT是特定于“关联的数字Pin Widget”，所以也许这个重叠解释了VrefEn不适用于这样的小部件。 它还指出VRefEn的有效值取决于PinCaps，所以推测数字Pin小部件的PinCap不包含任何有效的VRefEn值。</p><p>如果你沿着这条路走下去，你应该计划阅读大量的东西，让整个过程神秘化。</p></blockquote><h4 id="unsolicited-response-未经请求的响应"><a class="markdownIt-Anchor"

0x19 0x707 0x20</code>之类的语句,只是在睡醒唤醒后<code>CodecCommander</code>已经无法执行<code>hda-verb 0x19 0x707 0x20</code>这样的语句了,而<code>ALCPlugFix</code>却是以守护进程的方式存在于系统中,无论什么时候它都会监听声卡的状态,该切换时它就会发出命令切换,这样就保证了声卡总是可以工作在正确的状态下.</p></blockquote><p>基本上所有的耳机睡眠后没有声音的,只需要使用一条命令:<code>hda-verb 0x19 0x707 0x20</code>,就可以让你的耳机出声的.<strong>当然前提是你得先加载了<code>CodecCommander</code>这个驱动</strong>.估计我写完这段你们看完了还是一头雾水,我教大家一个简单的记法:<code>ALCPlugFix</code>作用于耳机,所以你需要知道自己的两个耳机节点,而<code>0x19</code>是耳麦的麦克风输入节点,只要找对了耳麦的节点,一条命令就可以搞定你的耳机切换.</p><h3
