OBS has no audio inputs. It seems like it was disconnected from the computers' audio

I'm running Ubuntu 23.04 with Kernel 6.2 Low-latency. I have this issue since the last week and my last message was not published for some reason. I really don't know what to do, and OBS don't give any message from the command line, so I don't know what to say about the error. Please help me, I really need OBS working.
I'll post the log from the command line, but it didn't give any error.
I'm running OBS 29.0.2. I had the last one from the PPA repository, but it stopped working the same way.
A thing I must say is that audio from droidcam OBS is working, but the computer's audio is not.

Is the log file

I ran obs --verbose from the command line and found this:

debug: obs_source_output_audio: Null 'audio_in' parameter

Anything else seems ok.
Any ideas? I'd thank you a lot.

That sounds like your system has not loaded an audio driver for your sound board. I have been through this myself, there are lots of websites that lead you through debugging. Starting with "lspci" in a terminal to make sure your sound card is detected, and what model it is.

Exit OBS, and use the OS Sound settings to test your hardware. Once you have that working, return to OBS.

I've put lspci | grep Audio. My system has already loaded audio driver.

root@roberto:/home/sergio# lspci | grep Audio
00:01.1 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] Kabini HDMI/DP Audio
00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD] FCH Azalia Controller (rev 02)

I got sound by Bluetooth and it's recognized by pulseaudio. Monitors, microphone, etc.
I just have problems with OBS Studio, and weirdly, Audio from Droidcam OBS works, so I really dont know what's going on.
I'll attach the log.
Running it as Root

No, lspci has ONLY identified your audio card. this does not indicate if a driver was loaded. Try lspci -k This will list the Kernel driver assigned to each device. From the fist post I expect you will have no kernel drier assigned to this card.

In my own case, i had to specify a DELL driver option to get my sound working.

Bluetooth is a totally seperate "hardware" and "driver" system. OBS will only use the audio speakers currently set for OS default.
