[solved] No HDMI sound with RX580

Message

Elleni · Post by **Elleni** » Tue Jan 02, 2018 2:14 pm

I migrated gentoo to a new box. On the old one, I had an amd R7 250 (http://dev1.club-3d.com/index.php/produ ... .1604.html) with hdmi enabled soundoutput. All working well.

Now on the hardware (Saphire Nitro+ RX580 Special Edition http://www.sapphiretech.com/productdeti ... 9&lang=eng), there is no soundoutput over hdmi.

Is this still correct ?
https://wiki.archlinux.org/index.php/AM ... 2FDP_Audio
The open source AMDGPU driver relies on the DC (formerly DAL) code that was pulled into the 4.15 kernel. Until 4.15 Kernel is available in official repositories, audio support for HDMI and DisplayPort will not be available, unless using 4.15 kernel. (...) Another way to get HDMI and DisplayPort audio is to install the AMDGPU PRO driver.

How can I install 4.15 gentoo-sources kernel, Latest unstable is 4.14.10-r1 or do I really need amd-gpu pro which is not in portage?

There are no -rc kernel sources available as ebuilds, so you'll either have to wait until 4.15 is released (in a week or two) or download/git-clone it off kernel.org.
There's a dev-libs/amdgpu-pro-opencl package in portage, but it sounds like it doesn't contain the full driver and so won't help here.

(I have the same problem FWIW, but I'm working around it with pulseaudio-over-ethernet)

Elleni · Post by **Elleni** » Tue Jan 02, 2018 2:55 pm

Thanks for your confirmation, so I guess its not a problem of misconfiguration of my side

I guess, I ll wait and/or try amd-gpu installation on top of amdgpu to see where it gets. Your mentioned workaround with pulseaudio over ethernet sounds interesting, but I ll have to see, wether I find some usefull info to see, if that could help me get sound over to my tv

Post by **NeddySeagoon** » Tue Jan 02, 2018 4:10 pm

Elleni,

4.15.0 has a new amdgpu driver. Its worth trying.

Code: Select all

emerge git-sources

will get you the current release candidate.

Of course, it might drink all the beer in your fridge too :)

I seem to remember that hdmi audio is in earlier kernel but its disabled by default.
You need a kernel parameter to enable it. Of course, it will be disabled for good reasons.
I've not tried it.

Ant P. · Post by **Ant P.** » Tue Jan 02, 2018 4:15 pm

It's there but I have the same symptom as Elleni shows in the first post: the card shows a lot of HDMI outputs (5 in my case), but they all emit no sound. Presumably 4.15 contains the magic dust needed to connect the HDA codec to the video output.

Elleni · Post by **Elleni** » Tue Jan 02, 2018 8:07 pm

Maybe I ll try git-sources to see, wether there is sound in hdmi, else I ll wait some weeks till gentoo-sources-4.15 will be in tree. Thanks

According to radeon wiki, boot parameter radeon.audio=1 is only needed for kernels older than 3.13 and thus is enabled by default, so I never tried setting it.

Aquous · Post by **Aquous** » Sat Jan 06, 2018 3:52 pm

For some cards, you also need to add

Code: Select all

amdgpu.dc=1

to the kernel command line

Elleni · Post by **Elleni** » Mon Jan 08, 2018 8:37 pm

I tried

Code: Select all

amdgpu.dc=1

and also the obsolete

Code: Select all

radeon.audio=1

without success.

So I will try git-sources now and report back.

Elleni · Post by **Elleni** » Mon Jan 08, 2018 8:56 pm

Mhm, it does not work eather with git-sources-4.15-rc7

I guess, next thing to try would be to install amdgpu-pro

Elleni · Post by **Elleni** » Mon Jan 08, 2018 10:59 pm

failed @ installing amdgpu-pro, but opened a separate new thread for this one. Hope it works with it, else I don't know, what I could try.

Elleni · Post by **Elleni** » Sun Jan 21, 2018 1:44 am

The combination of Neddy's and Aquous' comments did the trick. I had only tested amdgpu.dc=1 with 4.14 kernel. Now re-tested with this kernel commandline and git-sources and have hdmi sound output

Thanks guys

Ant P. · Post by **Ant P.** » Sun Jan 21, 2018 7:21 am

That's good to hear; I've been using a dumb pulseaudio-over-LAN setup in the meantime (dropouts like it's 2004!) and it'll be nice to restore some sanity to my cable management...

Elleni · Post by **Elleni** » Sun Jan 28, 2018 11:27 am

I successfully installed amdgpu-pro driver, but hdmi sound does not work with it, at least not out-of-the-box.
