No sound through displayport on R9 290x

Post by TidalBurn »

I have a AMD R9 290x using the propietory driver 14.6 beta. I use the displayport cable, plugged directly into the gpu, which achieves video but fails to play sounds.

Code: Select all

    Playback/recording through the PulseAudio sound server
null
    Discard all samples (playback) or generate zero samples (capture)

It seems to show that only intel sound exists. It does not seem to reconize the radeon sound.
I don't honestly know how to fix it. I'm using Linux Mint 17 64bit.

This may be no help.

Rightclick the volume control to open Sound Preferences. Check what shows in the Hardware panel, and check what is toggled in the Output panel.

(That's in Mate, anyway. Cinnamon should be similar. No idea about XFCE these days.)

I upgraded the linux kernal,

Code: Select all

sudo apt-get install linux-generic
, edited the /etc/default/grub and changed the GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" by adding "radeon.audio=1" to the end. I installed the xorg drivers for the gpu. After I rebooted, sound still didn't come back. Then I saw an option in the sound menu that wasn't there before. However, it only sounds clean through headphones. Through the monitor (where the speakers are), its really garbled up. Help?

Thanks, ofb! It was the answer for me.

Though for the life of me, cannot understand why that doesn't work when the Sound Preferences are opened from the Start Menu, rather than the Sound Icon. Displayport shouldn't be so tricky to configure, it was working fine on Linux Mint 13 MATE x64. Had to fiddle around with Mint 17 also, added PulseAudio, which fixed the issue on that release, but didn't on 17.1.

System Specs:

Linux Mint 17.1 MATE x64
Dell XPS 8700
i7-4770 CPU
12GiB RAM
MSI R7770 PMD1GD5 (AMD Radeon HD 7770)
Intel HD Graphics (Disabled)
180GiB Intel 330 SSD
AMD fglrx proprietary driver activated

Hopefully this will keep the Topic alive, took me a couple of hours to find. Again, thanks for the fix, reinstall is my last option to revert to.

Happy New Year!
