Kubuntu 24.04 has no audio

Kubuntu 24.04 has no audio

My PC has no audio. I use Kubuntu 24.04 and KDE Plasma 5.27.12. I know nothing about computers. My monitor is a HQ 19.5". Apparently it has no audio output, but the audio also doesn't work if I try and connect earphones. I get audio only when I connect my CPU to the TV in the living room. Should I buy a new monitor?

Specifications:

   OS: Kubuntu 24.04
   KDE Plasma Version: 5.27.12
   KDE Frameworks Version: 5.115.0
   Qt version: 5.15.13
   Kernel version: 6.17.0-35-generic (64-bit)
   Graphics platform: X11
   Processors: 4 × AMD Ryzen 3 2200G with Radeon Vega Graphics
   Memory: 5.7 GiB of RAM
   Graphics processor: AMD Radeon Vega 8 Graphics

The audio system shows 2 outputs (HDMI and Pro Audio) which I can select with or without earphones connected, and I tested both with the earphones connected and there was no audio. I connected the earphones through the top and back connectors, and I tested with both outputs listed above. In the past I also tried connecting speakers to it, but it still had no audio.

Top Answer/Comment:

Comment: It seems you're expecting the OS to guess which sound output to use and that's not how it works. If it works automatically with a TV then it is defaulting to HDMI audio, so it just works. OTOH, the same default is applied when connected (HDMI or DisplayPort) to a monitor without audio. It doesn't automatically switch from that to the internal analog outputs (speakers or headphones). Make sure to go to System Settings > Sound and select the intended sound output. This isn't Ubuntu specific - any OS allows selecting from multiple sound outputs - and no programming required, obviously.
