也许是宏碁Swift 3 [Realtek ALC256]上声音问题的一个解决方案？
也许是宏碁Swift 3 [Realtek ALC256]上声音问题的一个解决方案？
提问于 2021-10-29 10:50:07
众所周知，宏碁Swift 3，以及一般使用Realtek 256音箱的设备，对扬声器、耳机和内部麦克风都有问题。
不过，我是来找你帮忙的，也许，我想找个解决办法。
我和我的一个朋友有一台笔记本电脑:在他的笔记本上的扬声器，耳机，特别是内部麦克风工作！唯一的问题是，当耳机插入时，必须手动选择耳机输出，而不是扬声器输出。
在我的笔记本电脑中，情况完全不同:最初我只有‘虚拟输出’作为输出设备，而空白作为输入设备。然后，添加了options snd-hda-intel model = generic和options snd-hda-intel dmic_detected = 0，我终于能够看到Seaker，耳机和内部麦克风，但没有工作。只有从蓝牙设备我可以听到声音，但内部扬声器，千斤顶耳机和内部麦克风不工作！当然，我用alsamixer、pavucontrol或hdajackretask尝试了很多东西，至少可以让演讲者工作，但没有成功。
我们都在运行Ubuntu 20。
我不是Linux专家，但我尝试搜索这两种设备的不同之处。我发现了pacmd list-cards输出和Alsamixer的不同之处。N
在工作装置上，pacmd list-cards的输出是

，而在不工作的设备上
那么，现在的问题是:你们中有人知道问题是什么以及如何解决吗？如何使不工作设备具有与工作设备相同的设置？我看到他们不同的声卡设置和固件。
如果你需要任何其他输出，我会立即编辑这篇文章！
编辑:我给出两个命令的输出：cat /proc/asound/modules和dmesg | grep snd。
1a.工作装置上的cat /proc/asound/modules给0 snd_soc_skl_hda_dsp
1b。不工作设备上的cat /proc/asound/modules给0 snd_hda_intel
2a。工作设备上的dmesg | grep snd返回

确保安装了声音开放固件包(Debian/Ubuntu上的firmware-sof-signed)。
如果Linux仍然坚持使用后备驱动程序(snd_hda_intel)而不是SOF驱动程序(snd_soc_skl_hda_dsp)，则可以通过在/etc/modprobe.d中创建一个文件(如/etc/modprobe.d/alsa.conf )来请求后者，该文件的内容如下：
options snd-intel-dspcfg dsp_driver=3如果由于某些原因而不能工作，您可以更明确地：
blacklist snd-hda-intel
options snd slots=snd_soc_skl_hda_dsp更改应在下一次重新启动时生效。在更多有关HD-音频驱动程序的注释中有许多来自内核文档和博士的很好的故障排除信息。
另外，您可以尝试禁用Fast / Fast，以确保在Linux启动之前正确地重置音频硬件。
