Linux Mint DispplayPort audio issues

Post by pendy » Tue Dec 03, 2019 9:52 pm

Hi!

So i recently installed Linux Mint 19.2 Tina x64 on one of my PC that is hooked up to a older 32' Apple Cinema Display. For some reason it wont recognise the built in monitor speakers like in Windows or other distros. In the PulseAudio control panel it just shows "HDMI Audio [Radeon HD 6950] Digital Stereo (HDMI)" and i can hear a little bit of really silent audio coming out. I've tried: plug in the monitor to another display port slot, Kill running Pulse audio daemon, reinstall Pulse Audio, fiddle around with the GPU driver and alsamixer through terminal but nothing is working so far. Any help is greatly appreciated. Thanks in advance!



Cheers!

Hi pendy, and welcome to the forum.

Let's see the outputs of inxi -Fxz, aplay -l and pacmd list-sinks. Please have something playing sound when you run that last one.

Your outputs look fine. See if this gets the HDMI audio working:

Delete the files in /home/YourUserName/.config/pulse then run pulseaudio -k in the terminal. You may need to restart whatever you're using to play sound.

Good luck.

ROFL! You're not the first, and won't be the last to have that issue!

Glad you got it figured out. :D
