No sound cards available but there are at least TWO

Asked by Peter S on 2020-03-20

Hi I'm running Debian 10 and forgive me hat I couldn't find anywhere better than here to ask my question.
I tried to install the realtek alc665 sound card on my laptop and failed. As a result now no media can be heard through speakers or headphone. I have included some of the results of what i've done so far but please don't forget to refer to the link that I've put at the end of this post.
Here is the output from lspci | grep -i audio :

00:1b.0 Audio device: Intel Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 06)
 Subsystem: Dell 5 Series/3400 Series Chipset High Definition Audio
02:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev a1)
 Subsystem: Dell GF108 High Definition Audio Controller

and this is the output from aplay -l:

aplay: device_list:272: no soundcards found...

Here is a link to alsa information script that was ran on my machine:

What should I do to bring my sound cards back?

This is support for Ubuntu only, and not for Debian.

From your Output:

!!ALSA Version

Driver version:
Library version: 1.0.14
Utilities version: 1.1.8

On an Ubuntu System I would suggest to reinstall all sound and kernel packages (see step #1C in ) but I do not know how to do a similar action on Debian.

You should probably try

This is Ubuntu support only. The Debian forum will be where your distribution is suppored

Can you help with this problem?
