The Radeon driver is already pre-installed in Ubuntu. Due to this, dynpm only works when a single head is active. It also needs firmware-linux-nonfree package to get it to work. Other options there might be needed as well, e. Muting and un-muting in rhythem box does not fix the HDMI sound problem. The options from the Sound card support menu need only to be set if the card supports HDMI or DisplayPort audio and you want to use it. Note With more than one monitor connected, the memory clock will NOT be on full speed as it was before.

After these changes, you may use as many monitors as possible without an increased power consumption of your system. On cards that are supported by radeonsi starting at Southern Island, see the feature matrix make sure to not only specify “radeon” but also “radeonsi” as the driver.

Despite the pavucontrol showing audio being sent through the 4th display port, no audio is actually received on the other side. Note With more than one monitor connected, the memory clock will NOT be on full speed as it was before. If you see errors like “glamor detected, failed to initialize EGL. Audii R6xx and newer radeons have an internal thermal sensor that is exposed by the driver on most cards that utilize it.


[SOLVED] Radeon HDMI no audio and video faster

It also enables clock and power gating. Another solution is to enable the pulseaudio USE flag, update the system and use pavucontrol to set the HDMI port as fallback or use pavucontrol to change manually which application uses which audio port. Changed in alsa-driver Ubuntu: To get the temperature on asics that use i2c chips, you need to load the smd hwmon driver for the sensor used on your board lm63, lm64, etc.

Also running xrandr –output HDMI-0 –set audio on produces this as output: Support for older AMD audjo ATI graphics hardware is provided by the xserver-xorg-video-ati driver wrapper package, which depends on three hardware-specific driver packages: Page History Login to edit.

Power management is supported on all asics r1xx-evergreen that include the appropriate power state tables in the vbios; not all boards do especially older desktop cards. If you have a laptop that’s getting too hot, try setting the power management profile to low.

The audio also doesn’t work for me with the driver installed.

ALSA playback test through plughw: If you see “no” instead of “enabled”, then you’ll have to look earlier in the log to see why it’s been disabled. I can confirm the bug and the workaround both hold on an up-to-date Precise system with a Radeon HD Neither this nor the AMDGPU article cover installation and configuration of the closed source drivers see the next paragraph.


To know which version of the Linux kernel you have installed, type this text in a terminal window: The Radeon driver is already pre-installed in Ubuntu.

Sun Oct 2 Grub shows up but when i select it i just get a black screen. In some cases it appears the ‘auto’ settings don’t work correctly, so make sure to explicitly enable the integrated graphics. If this is the case, you have a different bug.

As a result, the power consumption increases as soon as you activate a second monitor because the GPU hardware wants it so. Warning There are several options to tweak the radeon driver and some of these might break your desktop, so if you are uncomfortable with the console better stick to default.

The “dynpm” method dynamically changes the clocks based on the number of pending fences, so performance is ramped up when running GPU intensive apps, and sudio down when the GPU is idle.

It is possible to check the permissions using getfacl:. Check the version of Ubuntu you have installed: You can see this in your Xorg log:.
