HDMI/DP output device not recognized

jaramo · 6 March 2021 17:03

Hi,

I’m new to manjaro and just set up a machine that will be my multimedia box.
It’s connected to my TV using a DP->HDMI converter. The TV is connected to a Yamaha AVR using ARC. But I can’t get sound over DP.

I’ve already spent half of today looking around on the internet and trying a few things (Kernels 5.4, 5.10 and 5.11, Kubuntu 20.10, connecting directly to the AVR instead of the TV, plug into second DP, reboots, turning TV/AVR off and on again) but it seems no matter what I do there is just no HDMI output device found.

Works fine using Windows 10 - but I’d rather not that be the solution. But being able to get sound to my soundsystem is the whole point of a multimedia box…

I’ve read that a second sound device should show up for HDMI/DP. But it doesn’t.

As you can see, all analog device. No HDMI/DP. Therefore nothing to select in pavucontrol.

Can anyone help me?

Is this an active converter? (I.E. Does it have its own power supply?)
If no, is it from a reputable brand?
If no: Change the connector

That doesn’t mean anything: the converter might have a Windows driver, but no Linux driver.

That kernel is EOL: upgrade to 5.4 LTS (Long Term Support) or 5.10 LTS (try both: you might get lucky with your Cheap! Chinese! Crap! connector. )

jaramo · 7 March 2021 16:12

No, it is not an active converter. I was not aware those needed drivers. So the converter might actually be the issue here.

Is there a resource that would help me find a compatible converter?

So the default install leaves me with a system running on a EOL kernel? Meh.
As I wrote in my first post - I already tried 5.10 without success.
Also: The Kernel application only lists 5.10 but no 5.10 LTS.

Fabby · 7 March 2021 17:11

It’s called a store and you walk in and test it out and buy if it works.

It’ll get updated soon. Please don’t kill the messenger.

5.4?

it does: https://kernel.org

jaramo · 7 March 2021 17:36

Well, having to try them out myself is not going to be much help in the sense of making the task easier…
Not that I even could go to a store right now. Or that there would be stores nearby that had different converters in stock and let me try them out on a desktop PC i brought with me…

I also tried 5.4, as stated in the initial post.

And Manjaros Kernel application does not say 5.10 is LTS (even though it is)

Fabby · 7 March 2021 20:20

I have an active one that converts from s-Video, VGA, HDMI, DVI, to all of the same, made in Deutschland, but the brand doesn’t exist any more, so I can’t help you there…

I use the command-line, so I have to have a look at https://kernel.org anyway, but that looks like a bug, so @philm How do I file a bug for 5.10 not being marked LTS in the kernel GUI?

jaramo · 9 March 2021 15:46

So following your advice I got a HP HDMI Port Flex IO. (Believing it is an internal active converter)
But that didn’t help either. No audio device even without the cheap passive converter. (But a lot of noise - green pixels/lines - in the image that comes over the HDMI connection…)

So back to square one. For now I’ll dualboot Win10. But I hope someone can point me in the direction of a solution.

Regarding your guess that there might not be linux drivers for my cheap adapter I’m still a bit confused:
As far as I read the last couple of days those shouldn’t need drivers. (I mean - how COULD a passive component even interact with a driver?!)
Dual-mode DP should output a HDMI-signal over the DP-port and the converter is just a plain cable. At least that is what various sources say.
So maybe the issue is with the dual-mode DP support. Any ideas how to investigate this further? My google-fu is not strong enough…

I see lots of problems with converters under Linux, but mine never posed any problems with me. You’re the first one that changed to an active converter that still has an issue, so my knowledge ends there but maybe our resident sound expert @nikgnomic has a better idea?
