升级到 18.10 后没有声音，只显示一个虚拟设备

Question

更新到 Ubuntu 18.10 后，我的声音设备不再被识别。只显示了一个虚拟设备。

我有一个板载英特尔设备：

lspci -nnk | grep -A2 Audio
00:1b.0 Audio device [0403]: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)
    Subsystem: Intel Corporation 7 Series/C216 Chipset Family High Definition Audio Controller [8086:2036]
    Kernel driver in use: snd_hda_intel
    Kernel modules: snd_hda_intel

该命令pacmd list-cards不显示任何设备：

:~$ pacmd list-cards
0 card(s) available.

此消息/var/log/syslog可能与问题有关：

Oct 19 21:02:06 MyComputerName pulseaudio[14331]: E: [pulseaudio] 
backend-ofono.c: Failed to register as a handsfree audio agent with 
ofono: org.freedesktop.DBus.Error.ServiceUnknown: The name org.ofono 
was not provided by any .service files

有人有同样的问题吗？我怎样才能解决这个问题？
