Hi everyone,

I need some help with the configuration of the sound system of my Intel NUC10i7FNH.

Background:
Originally I was running Fedora and had the sound system setup to work with the various video conferencing software (Zoom , Skype, Bluejeans, etc.). A week or so ago, I logged onto my system and the sound didn’t work any more. I don’t know what caused it, but I read up on various sites on the net and tried to correct things fiddling with alsa and pulseaudio. To no avail, so I decided to change the Linux distribution and installed Linux Lite with a Xfce desktop environment. I’ve managed to get the system setup to some degree, but would like to some help to a) improve it and b) lock the configuration to disallow any changes to the system.

Problem Statement:
1. The hardware works. This is a software/configuration problem. I have played music using VLC or aplay, recorded from the internal mic using arecord, and at the moment the video conferencing software work.
2. My display has no speakers, and therefore all sound output has to go through the analogue ear phone jack on the front of the NUC, either via a set of external speakers or headphones.
3. I use a Microsoft usb camera as the video source for the video conferencing sfoftware.
4. However, I rarely use the camera for video conferencing for work, since we typically share our screen showing documentation to review and discuss. So I would like to have the sound configured in such a way that I can hear through the headphones and speak through either the headphone or internal mic, without the usb camera being plugged in. This is the improvement part (point a above).
5. For point b above, I would like to setup a configuration file that will force the system to use the same configuration for the sound system.

Description of the current setup:
Pavucontrol show the following hardware -see attached JPG.
For the built-in audio I have the configuration options - shown in the attached JPG.
As you can see there is no option for a simultaneous analogue input and output. If I choose “Analogue stereo output”, I can play sounds through VLC and aplay, but I can’t record using arecord. The video conferencing software don’t see any mic’s. If I choose “Analogue stereo input”, I can record using arecord, but I can’t play sounds through VLC and aplay. The video conferencing software don’t see any speakers. Is there a way to write a configuration file for either alsa or pulseaudio which would provide access simultaneous access to both analgue input and output?
If this can’t be done, I could live with using the camera microphone as is currently configured. In either case I would like to force the system to use the selected configuration and not make any changes due to system updates, etc.

Post the output of Both need root permissions - hence ust 'sudo' if you have not got root

uppon a time.. conflicts in 2 sound sources made me blacklisting few modules.. and it worked again https://www.linuxquestions.org/quest...ve-4175534057/
have a look there

Thanks business_kid, for your reply.
Output of lspci was provided in the original post.
Output of lsusb shown below:

Thanks floppy_stuttgart! Much appreciated. I will have a look.

Adding "snd_hda_codec_hdmi" to the blacklist file made no difference. Even after a reboot, the module was still loaded and the HDMI configurations were still available fr selection in pavucontrol.

I will however attempt to set the index order of the sound "cards" via kernel module options - that should take care of my 2nd question.

That leaves the 1st question:
Does anyone know how to configure the system so that I have simultaneous analogue input and output?

Thanks for the help guys!!

Perhaps it made no difference because the modules were already preloaded by the initrd.

There's also /etc/pulse/default.pa where you can set stuff.

you use ubuntu? look there for hints regarding HowTo blacklisting https://askubuntu.com/questions/1103...kernel-modules
