Fedora 29、Intel HD 音频、扬声器或耳机插孔没有声音

我使用的是 Fedora 29,但我的机器听不到任何声音。就操作系统而言(当使用 alsamixer、pavucontrol 等时),声音应该正常工作,没有任何静音或类似的情况,但扬声器或耳机插孔没有声音。我尝试卸载/重新安装pulseaudio,尝试使用各种模型选项创建/etc/modprobe.d/sound.conf(也尝试将其称为/etc/modprobe.d/alsa-base.conf),例如:

# cat /etc/modprobe.d/sound.conf
options snd_hda_intel model=imac27

这是 27 英寸 iMac (iMac18,3)

我在下面发布了有关该系统的一些相关信息,如果需要任何进一步的信息,请告诉我。如果有人能指出我正确的方向,我将不胜感激。

也许这可能会为某人提供线索?

# aplay /usr/share/sounds/gnome/default/alerts/bark.ogg
ALSA lib pulse.c:243:(pulse_connect) PulseAudio: Unable to connect: Connection refused

aplay: main:828: audio open error: Connection refused

(是的,我已经用谷歌搜索了这个错误相当广泛)

基本信息:

# uname -r
4.20.4-200.fc29.x86_64

# lspci | grep Audio

00:1f.3 Audio device: Intel Corporation 100 Series/C230 Series Chipset Family HD Audio Controller (rev 31)
01:00.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 570/580]

我只想要普通的内置扬声器和耳机插孔,因为这些机器将部署在教育实验室中,我对启用 HDMI 音频(Radeon 设备)不感兴趣。
