ENABLE SOUND SURROUND 5.1 IN DEEPIN


Very good! I am MLopez_fpv as many of you know me from the Telegram channel ... I bring you a little tutorial that some of us like us have an 5.1 home cinema and we also have TVs connected by HDMI to enjoy our movies in Kodi or watch IPTV content or other ... with the following tutorial I teach you how to configure deepin to have the necessary 6ch audio to enjoy surround sound and quality with deepin.

We open the terminal and we put the following:

sudo nano /etc/pulse/daemon.conf

I use dwarf in the terminal because I'm used to it but you can use gdit, vim etc ...

then we must search and edit the following lines:

resample-method = speex-float-6
enable-remixing = yes
enable-lfe-remixing = yes

Then we locate the line default-sample-format and we modify it in the following way:

default-sample-format = s24le
default-sample-rate = 96000
default-sample-channels = 6
default-channel-map = front-left, front-right, rear-left, rear-right, front-center, lfe

finally we save the changes by stopping with control + x and pressing S to say yes and press Enter.

Finally it remains to configure in alsamixer and move from 2ch to the 6 needed for the 5.1
we wrote in the terminal:

alsamixer

And we press Enter... and then we can press F6 to select the audio card.

In my case I select the motherboard card where the connected 3jacks of the home cinema are.

Then we go to the right and in channels we press the arrow up and upload it to 6ch leaving it like this:

Once this is done we can go out with Esc and finally we just have to leave the changes saved in alsa, so we put the following in the terminal and press Enter:

sudo alsactl store

this is necessary so that the 6ch configuration is saved when the restart is made.

And we would have the sound to 5.1 in deepin, you just have to reboot the system and enjoy the surround sound!

Thanks and greetings to the entire GNU / Linux community!

Awesome mlopez Thank you very much, maybe this will help me solve an old problem that I have with the second audio channels on my motherboard

It occurs to me that it is valid for 7.1 by changing the channels to 8 and referencing the necessary outputs in the configurations.
