# snd\_fm801.4

`snd_fm801` — Forte Media FM801 桥设备驱动

## 名称

`snd_fm801`

## 概要

`要将此驱动编译进内核，请在你的内核配置文件中加入以下行：`

> device sound device snd\_fm801

`或者，要在引导时以模块形式加载驱动，请在 loader.conf(5) 中加入以下行：`

```

## 描述

`snd_fm801` 桥驱动允许通用音频驱动 sound(4) 附加到基于 Forte Media FM801 芯片组的音频设备。这是 OEM 制造商在各种部件中使用的常见芯片组。

## 硬件

`snd_fm801` 驱动支持基于以下芯片组的音频设备：

* Forte Media FM801

## 参见

sound(4)

## 历史

`snd_fm801` 设备驱动首次出现于 FreeBSD 4.2。

## 作者

本手册页由 Joel Dahl <joel@FreeBSD.org> 编写。

## 缺陷

Forte Media FM801 芯片组是一种 PCI 桥，而非真正的声音控制器，因此可能存在无声卡支持。问题在于带声音支持和不带声音支持的芯片组都使用相同的 PCI ID。这使得无法确定安装的是哪一种。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://book.bsdcn.org/man/man4/snd_fm801.4.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
