Ati HDMI - Not detected sound card

English Hardware
1

Hello guys,

I have my tv plugged on to my laptop through a hdmi port. I can’t get sound in the tv loudspeakers. It seems that the the systems saws the hdmi board as disconnected all the time, since it is showed on the kde’s control center, but in a ‘unselectable’ state and gray color. I have already tried passing ‘radon.audio=1’ to the kernel command line but it was worthless (that’s all I could find on google). Any ideas?

My system: opensuse 13.2 64bit on hp dv7 laptop, hybrid muxless intel/amd graphic card.

Is the HDMI device showing in the Yast -Sound card section?

Try moveing it to first position

Also pavucontrol is great at straightening this kind of thing out.

I’ve had similar problems with both AMD Radeon and nVidia devices. In
both cases, the only way I found to get sound was to install the
proprietary drivers. As soon as I had installed a driver, the
pavucontrol configuration profile switched from “unplugged”. With the
default kernel drivers, there had been no profile in the drop-down list
that didn’t have “unplugged” against it.

assumption: sound is ok via internal speakers

configuration

hp-g7-2248sg laptop connected to Samsung tv via hdmi cable, Radeon driver,

no auto switching has been found for the sound between internal sb and hdmi installs

manual selection is required via
-Sytem Setting
–Multimedia (Hardware group)
— Audio and Video Settings
----Audio Playback (all)

if the hdmi cable is connected and sound is required from the tv speakers
‘RS780 HDMI Audio [Radeon (HD) 3000 Series] Digital Stereo (HDMI)’ (ymmd)
has to be first in the list

if the hdmi cable is not connected the and sound is required from internal speakers
‘Build-in Audio Analog Stereo’ (ymmd)
has to be first in the list

in vlc the selection is via
-Audio
–Audio Device
then select from pull-down menu

I have configured hdmi card as the first and configured the laptop speakers in model parameter. Now, both appears as disconnected for pulseaudio, as you can see on image. Only a dummy device appears as available.

No devices are available to be enabled or disabled on pavucontrol too.

Pacmd says:

0 card(s) available.
0 sink input(s) available.
0 source output(s) available.
0 cache entrie(s) available.

I would rather think this is a f*cking annoying bug. I’m really frustrated after been using linux for the last 13 years and it still hard to make a so basic stuff work.

Did you install the AMD driver as was suggested??

The syntax you typed in your post is wrong. Is that what you typed on your PC ?

The boot parameter is ‘radeon.audio=1’ and not ‘radon.audio=1’.

if nothing else works try,

in -yast, --sound,
make sure ‘Cedar HDMI …’ is ‘Set as the Primary Card’ (under the ‘Other’ button)

then make sure ‘Play Test Sound’ gives an output (under the ‘Other’ button)

if it doesn’t try deleting the card and then adding it again

then try a cold reboot

(after most major updates this process is necessary on at least one laptop/pc)

Guys,

I just removed everything under .config/pulse/ on my homedir and then restarted pulse. Now works fine. I already knew this trick but just now I could realize that the pulse config dir has changed. It used to be located on ~/.pulse, but now on 13.2 it is located in ~/.config/pulse, as I said above.
