我刚买了一台名为 Asus ROG Strix G15 G512LW 的新笔记本电脑，配备 i7 和 Nvidia RTX，但根本没有声音。以下是我的一些设备信息：
$ cat /proc/asound/cards

HDA Intel PCH at 0xc5418000 irq 155
1 [NVidia ]: HDA-Intel - HDA NVidia

$ aplay -l

我尝试从 alsamixer 中选择 HDA Intel PCH 并检查是否有任何静音选择。
此外，感谢这个关于选项的线程，snd_hda_intel我尝试将下面列出的选项添加到 alsa 基础中：
$ sudo gedit /etc/modprobe.d/alsa-base.conf
options snd-hda-intel model=g50v
options snd-hda-intel model=g71v
options snd-hda-intel model=dell
options snd-hda-intel model= asus-a7j
options snd-hda-intel model=asus-a7m
options snd-hda-intel model= asus-laptop
options snd-hda-intel model=lenovo
但无论我尝试什么，我都无法听到任何声音。
顺便说一句，当我写信alsamixer并点击时，Enter我收到了这条消息：
$ alsamixer
cannot open mixer: No such device
So I reached it by writing `alsamixer -c 0` and its version is AlsaMixer v1.2.2
作为 Ubuntu 的新手，我已经尝试解决这个问题一周了，所以我认为寻求您的帮助是一个明智的决定。
