Davinci resolve plays no sound on ubuntu 22.10

Congratulations you have installed davinci resolve on ubuntu 22.10. But there is one small issue, it plays no sound. no

Why is it so?

Davinci on linux uses the ALSA sound subsystem, witch communicates directly with the sound hardware, but ALSA is a low level program that can support one program playing sound at a time. So every sane linux distro adds a sound proxy to allow multiple programs to play sound at the same time. Pulseaudio is the one used in ubuntu 22.10, it acts as a proxy that allows multiple programs to play sound at the same time.

How do you fix it?

Step one

Increase the bitrate on your sound driver.

Open the pulseaudio config file.

sudo nano /etc/pulse/daemon.conf

Find these three and set their values like this, dont forget to uncoment them (remove the ; in front of them)

 default-sample-format = s16le default-sample-rate = 48000 alternate-sample-rate = 44100

After you have done this restart your machine.

Step two

Create a asound.conf file in /etc/, it's the configuration file for alsa apps. This will tell davinci resolve to use pulseaudio

sudo nano /etc/asound.conf

Copy this into the file.

pcm.!default pulse
ctl.!default pulse

Restart your machine once again, and you should hear sound in davinci resolve.

Recommendation

It's better for your os to install davinci resolve as a deb file, since it doesn't follow installation procedures of debian distros.

For that there is an excellent tutorial at https://www.danieltufvesson.com/makeresolvedeb.
