Ubuntu 18.04 No Sound Card detected
Solution 1
Is your sound device blocked by some other processes? fuser
should list the pulseaudio
command only:
~$ sudo fuser -v /dev/snd/*
USER PID ACCESS COMMAND
/dev/snd/controlC0: justme 2067 F.... pulseaudio
/dev/snd/controlC1: justme 2067 F.... pulseaudio
/dev/snd/pcmC1D3p: justme 2067 F...m pulseaudio
If you see anything else than pulseaudio
as the assigned command, try to get rid of and restart pulseaudio like pulseaudio -k
(as user, not root). Afterwards pavucontrol
should list your device again ...
Solution 2
I had a similar problems with USB card (Asus Xonar U7) on Ubuntu 18.04
I solved it using instructions from this answer https://askubuntu.com/a/1104763/354702 by João Pimentel Ferreira
1) Remove the ALSA packages.
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
2) Reinstall the same packages.
sudo apt-get install linux-sound-base alsa-base alsa-utils
3) Install further audio addon packages
sudo apt-get install dkms build-essential linux-headers-`uname -r`
alsa-base alsa-firmware-loaders alsa-oss alsa-source alsa-tools
alsa-tools-gui alsa-utils alsamixergui
4) Be sure to add the user to group audio
sudo usermod -a -G audio username
5) reboot
sudo reboot

I upgraded to Ubuntu 18.04 and sound disappeared and showed the infamous "Dummy Output", I thought the problem was with alsa and pulseaudio so I removed them and reinstalled them but that did not fix it. I tried the command
aplay -l
The output was :aplay: device_list:270: no soundcards found..
I triedlspci
and the output was:00:00.0 Host bridge: Intel Corporation Skylake Host Bridge/DRAM Registers (rev 08) 00:02.0 VGA compatible controller: Intel Corporation HD Graphics 520 (rev 07) 00:14.0 USB controller: Intel Corporation Sunrise Point-LP USB 3.0 xHCI Controller (rev 21) 00:14.2 Signal processing controller: Intel Corporation Sunrise Point-LP Thermal subsystem (rev 21) 00:15.0 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #0 (rev 21) 00:15.1 Signal processing controller: Intel Corporation Sunrise Point-LP Serial IO I2C Controller #1 (rev 21) 00:16.0 Communication controller: Intel Corporation Sunrise Point-LP CSME HECI #1 (rev 21) 00:17.0 SATA controller: Intel Corporation Sunrise Point-LP SATA Controller [AHCI mode] (rev 21) 00:1c.0 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #5 (rev f1) 00:1c.5 PCI bridge: Intel Corporation Sunrise Point-LP PCI Express Root Port #6 (rev f1) 00:1f.0 ISA bridge: Intel Corporation Sunrise Point-LP LPC Controller (rev 21) 00:1f.2 Memory controller: Intel Corporation Sunrise Point-LP PMC (rev 21) 00:1f.4 SMBus: Intel Corporation Sunrise Point-LP SMBus (rev 21) 01:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

As you can see without Audio device.
I ran the alsa-info script https://gist.github.com/craftyjon/902247 and This was the output:

I have dealt with sounds problems many times before but at least each time the card was detected by
lspci
command I don't know if that is a hardware problem.UPDATE:
I restored the default BIOS settings and the soundcard is visible now. The problem now is that in pavucontrol, the option "Analog Stereo Duplex" and "Analog stereo Input/Output" for that matter are missing. I reinstalled pulseaudio and alsa but it did not work.

CL. almost 6 yearsThe audio device would show up on
00:1f.3
(either HDA or I²S). Check the BIOS. -

hussien eloy almost 6 yearspastebin.com/m9wFWMPb. Here it is.

CL. almost 6 yearsNothing but the HDMI output.

hussien eloy almost 6 yearsYes that is the problem. Analog disappeared from my configuration. The digital are the only ones remaining.

Derek Eden almost 4 yearswhat if you get no output
-
ChristophS almost 4 yearsFrom man page
fuser
: identify processes using files or sockets. At least pulseaudio should be listed, otherwise it does not access your soundcard. In this case your problem is not a blocked device and my solution won't help. -
yankee over 3 yearsIn my case
timidity
was shown as command. I killedtimidity
and immediately my sound card was back! I did not even need to restart pulseaudio. Weird...
