更新到Ubuntu 18.10后,我的声音设备不再被识别。仅显示一个虚拟设备。
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?
