KDE desktop install has no working audio - multiple fixes attempted
Hi all,
First post here, please pardon my dust on post etiquette.
Fresh install of Arch on a desktop - See following specs:
- KDE Plasma version 6.5.0
- Kernel version 6.17.5-arch1-1 (64-bit)
- Processors 12 × Intel® Core™ i5-10600KF CPU @ 4.10GHz
- Graphics Processor NVIDIA GeForce GTX 1080
- MOBO ASUS ROG STRIX
- Disk layout 500GB nvme with / and /boot
1TB nvme with /home
Attempting to gain functional audio after installation. Currently I have no audio out of any device. Sound indicators move when I change volume on the slider in both KDE and pavucontrol, indicating there should be a ping - but nothing. Nothing I am doing has worked after endless reboots and reinstallations from scratch. Wondering if the enlightened can help?
I have tried the following already:
1. Tried to install via archinstall, with AND without pipewire/pulseaudio after hearing archinstall has known issues, then tried installing after boot in the latter case with no dice,
2. checked systemctl, all pipewire, pipewire-pulse, wireplumber etc. are enabled and running - attempted stops and restarts of the services with no effect,
3. Quadruple checked pavucontrol and alsamixer to check my devices are not muted - they are not and I have checked both my HDA intel PCH and HDA NVidia sound cards,
4. Blacklisted snd_hdi_intel to try and remove proported issues with this module - this just gives me no devices at all,
5. Installed and reinstalled sof-firmware without the success had by many online.
Am I missing something? Appreciate all help you kind people can provide. Thanks.

Re: KDE desktop install has no working audio - multiple fixes attempted
Speakers plugged in properly and if you think they are where are they plugged into, the mobo, the monitor? What about the basics
sudo dmesg | grep -iE 'snd|sof'
aplay -lL
sudo fuser -v /dev/snd/*
amixer -c0
pactl list cards

Re: KDE desktop install has no working audio - multiple fixes attempted
Thanks for the swift reply.
One HDMI monitor (for now), plugged into my NVidia GTX 1080 graphics card - looking to use this as my output.

Re: KDE desktop install has no working audio - multiple fixes attempted
Mhm... I faintly remember nvidias hda codec having some issues recently but my info might be dated. FWIW to make sure we've covered the basics... you know that your monitor has speakers and you're certain they work by testing it with something "more likely to work" (Windows install, game console or so)? and they aren't muted on the monitor side (via the settings of the monitor itself)? The tech sheet seems to mention they should be present: https://www.acer.com/gb-en/monitors/ess … 8#pdpSpecs so that should™️ work fine
What output (if any) do you get from
speaker-test -Dhw:1,3 -c2you'd ideally hear some noise

Re: KDE desktop install has no working audio - multiple fixes attempted
Hello, pardon the late reply - work hours.
I am sure the speakers work on this monitor. I have also tried using a display port connected monitor I am sure works with the same lack of audio.
Your query:
$ speaker-test 1.2.14
Playback device is hw:1,3
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 64 to 1048576
Period size range from 32 to 524288
Periods = 4
was set period_size = 12000
was set buffer_size = 48000
0 - Front Left
1 - Front Right
Time per period = 5.002105
0 - Front Left
1 - Front Right
Time per period = 5.999940
0 - Front Left
1 - Front Right
Time per period = 6.000942
0 - Front Left
^C 1 - Front Right
Time per period = 2.662595This plays no sound at all. Sorry for the lack of helpful info - though I do know it is possible to get sound working on this setup as I have done it before with this very distro and machine a few days ago. I had to reflash that installation for another issue around partitions...
Do you recommend a reinstall or is there much else to try? Thanks again.

I'm not a Linux audio wizard so apologies if I'm confused here: wouldn't that be the third device on the Nvidia card? Would it not make more sense to use hw:1,0?

Re: KDE desktop install has no working audio - multiple fixes attempted
Got the following from your suggestion:
$ speaker-test -Dhw:1,0 -c2
speaker-test 1.2.14
Playback device is hw:1,0
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Playback open error: -2,No such file or directoryLooks like no luck, thanks anyway!

Re: KDE desktop install has no working audio - multiple fixes attempted
Ah yeah, I misread the aplay output. The third device on the nvidia card is exactly what you want.

Re: KDE desktop install has no working audio - multiple fixes attempted
Hi all,
Eureka - got it working. Posting the results of the first set of queries here for reference by others perhaps facing the same issue.
In short - by plugging in both a HDMI and a display port monitor, reinstalling sof-firmware, and rebooting (I think, I'll admit I was shotgun debugging by this point) - I managed to get the displayport monitor to output audio via the "HDMI 2" option in KDEs sound mixer.
See below the query results - hopefully this may help other weary travelers...
