"Dummy Output" for audio - yet aplay from CLI shows hardware and plays .wav file
Following process here: https:/
Now at Step 3 which uses an alsa-project.org script to capture system audio hardware/software information and directions to post that output on launchpad. Script output follows below.
NOTE: I have been wrestling with this sudden "Dummy output" issue for several weeks. I listened to audio on this system for most of the past week and most of today, but had to restart to fix an issue while trying to re-partition an attached USB drive. On restart "Dummy Output" reappears. Logically whatever is amiss cannot be an issue with drivers/hardware. I cannot have listened to audio on this Lenovo desktop this morning unless drivers/hardware are installed and correct. But multiple restarts over the past two hours have failed to re-establish working audio apart from the use of aplay from the command line.
Logically something is going awry on boot/driver loading/software loading. If I can, right now as I enter this text on this page do:
#> aplay -D sysdefault ding.wav
and hear the audio file, at the leat ALSA is correct. Again, logically, the issue is another audio component and not ASLA. Likely culprit is pulseaudio, but damned if I can figure it out. I've stopped/started pulseaudio dozens of times. pavucontrol shows the same information that the KDE AudioConfig controls show: "Dummy Output" for Playback Devices, and in Advanced NO hardware is shown (neither the Analog nor the HDMI, and there should be both, one for the output jacks on front/back of the case, and for the HDMI to my monitor that also has speakers).
After I submit this I will continue with Step 4 of the guide referenced above.
A google search for "Dummy Output" shows a LOT of people are having a similar issue.
Am also available at <email address hidden> for easier communication. If it helps, I'm a newly retired IT professional, though my work was not in operating systems, etc. I know my way around the command line and I'm unafraid of scripting having spent a decide as an app admin on Solaris systems (bash, perl, and powershell, though my perl is very rusty). Happy to get into the weeds if I can help get this problem fixed for both myself and other users.

Guy Stalnaker (gstalnaker) said : | #3 |
Very strange, naturally. A further trouble-shooting step, for gathering information, at the bottom of the referenced page, is to run
#> lspci -nn|egrep 'ultimedia|
Output PRIOR to my last reboot had two items:
Codec: Realtek Generic
Codec: IceCam USB (<-- this is not exact, but it did reference a macally USB cam plugged into the computer).
I edited /etc/modprobe/
options snd-hda-intel model=Generic
to
options snd-hda-intel model="Realtek Generic"
and restarted. Now, that same lspci shows complete different output:
Codec: Realtek ALC222
Codec: Intel Kabylake HDMI
The macally USB cam is gone, the Realtek item has a different value, and a new HDMI entry appears.
This is maddening. No change in hardware, nor USB port that cam is plugged into, yet the lspci command now shows that /proc/asound has different values.
AND ... the KDE pulse/phonon system shows the expected output options and "Dummy Output" is gone:
Advanced Tab
Built-in Audio (drop down, 3 options):
Profile: Analog Stereo Output
Digital Stereo (HDMI 2) Output
Off
I'm going to modify the alsa.conf file one more time
options snd-hda-intel model="Realtek ACL222"
Will report, hopefully, one final time, that sound remains functional and "Dummy Output" does not return.
Can you help with this problem?
Provide an answer of your own, or ask Guy Stalnaker for more information if necessary.
