Put the audio on my old LG 26LG3000 with my GTX 750 Ti by HDMI

I have visit this link, but I have seen that I have the last PulseAudio version installed (9.0):
https://www.freedesktop.org/wiki/Software/PulseAudio/

On the LXTerminal, I just typed:
pgrep -l pulseaudio
Then, the response for the command was: 1357 pulseaudio

So, I download lib32-libpulse from:
https://www.archlinux.org/packages/multilib/x86_64/lib32-libpulse/
Extract it to a new lib32-libpulse folder.

Also, I downloaded lib32-alsa-plugins from:
https://www.archlinux.org/packages/multilib/x86_64/lib32-alsa-plugins/
Extract it to a new lib32-alsa-plugins folder.

Follow this command line process:
sudo apt-get install xdeb
xdeb http://ftp.de.debian.org/debian sid main

But, I don't know how to install neither lib32-libpulse nor lib32-alsa-plugins.

First of all, thank you very much for everyone who could help me in this problem

Mixing Debian and Ubuntu packages will give you a big mess of a system. The dependencies are different and you won't be able to update your OS.

What is the output of:

wget -O alsa-info.sh http://www.alsa-project.org/alsa-info.sh && chmod +x ./alsa-info.sh && ./alsa-info.sh

Thanks

Sorry about the delay, I had a health problem.

- As ALSA asked me, I informed you.

Thanks a lot again, and sorry about the delay

This question was expired because it remained in the 'Open' state without activity for the last 15 days.

I found on the back of my TV an input to a 3.5 mm jack, that can be used to connect the TV with my PC, directly from the motherboard audio output, to mix the HDMI with the 3.5 mm jack.

So, that could be a choice to solve the problem.

Thanks
