DVI and USB Audio?

[TopherBarnett]

Well, since I don't have a TV with HDMI, I was really hoping I could run my OUYA on my computer monitor with an HDMI to DVI cable. I do get picture, but the resolution is horrible. I've contacted support about this, but have not received a reply in over a month. Apparently I am not the only one with this issue as it can be found all over the support forums. Not sure if it's a resolution issue or HDCP issue or something else, but I'm hoping some enterprising dev can figure it out.

On the same note, since my monitor doesn't have speakers and an HDMI audio extractor is about the same price as the OUYA, it'd be nice to be able to use a USB DAC to output audio to my desktop speakers. Apparently the SGS3 has it enabled, it just isn't in the stock android kernel yet: See Android Issue 24614

Anybody working on this or heard directly from OUYA support?

The resolution isn't an OUYA specific problem, it's the same on many devices. I believe it does have to do with HDCP. I know there are some people out there with similar situations as you that have a converter cable that works, but it's not very common. IMO this is something I believe they never thought would come up was a problem that seems to be more common than not.

And yes, any type of converter box or audio splitter is going to cost you. the HDMI to Component box that I was looking at that I heard works costs 150, so it's not really worth it.

As for the sound over USB, I haven't heard of that yet for OUYA, but I know it was actually part of android starting with 4.1. That does not mean it works with the OUYA, however, as it seems only a few phones/tablets actually have the ability. If you have a micro USB to USB adapter, you might try it through that, but other than that not sure if there's any options.

I was really hoping this thing would have a AUX port, but it doesn't. I know there's some devs working on pushing sound and video from android over a network, but it's still in early stages and as far as I know no one has it working yet.

Really hope someone finds a good workaround. I don't particularly want to buy a TV just for this little box.

 

[TopherBarnett]

Well this is interesting...I just installed CWM, and while in recovery it shows full screen and looks rather nice. This must mean that it's not an inherent problem with my screen or connection, but is something do do with the software. This makes a work-around seem feasible, no?

Just found a reply in the StockPlus thread in the Dev section, but thought I'd repost here since I don't have 10 posts yet and can't reply there:

This one, from what I understand it's Android compliant, so it just needs the standard USB Audio modules. I know the Nexus 7 got it working with certain kernels that had the necessary modules loaded. Jellybean was supposed to make this easy, but it's been hit or miss on which ROMs have the files.

I have the same USB audio adapter and it's not working for me either. Really hoping someone cracks this nut.

The issue with this is that the Ouya looks for screenmodes of 1920x1080p and 1280x720p in the monitor EDID.
Failing this, it reverts back to a letterboxed 640x480 screenmode.

There's a thread here with more info.

I have an old monitor that runs 1600x900 I use it on next to my computer just to root. If I could make it use 1280x720 and my logitech usb sound card I'd get more use from the ouya as it's now hooked to a shaerd TV. I can run my PS3 and xbox on the monitor at 1280x720 and get sound from the av outputs.

Good info on that thread, too bad nobody has seemed to make much progress though. My monitor is capable of up to 1920x1200 and supports 1280p and 720p resolutions. Sounds like the solution is either to get the EDID talking correctly, or hack in a way to override the OUYA settings and change the resolution manually.

I am running a HDMI Audio Switch (Ligawo HDMI Audio Switch ~35€) using a hdmi-cable between ouya and switch and a hdmi-dvi cable to connect the switch with my computer monitor. The switch comes with a cinch-output that is connected with my 2.0 Amplifier.

Funnily enough the switch also solves the resolution problem, I still have when connecting the ouya with my monitor via hdmi-dvi cable. Now my monitor runs brilliant on 720p.

I bet the switch provides some EDID spoofing. Most do in order to keep display sources from freaking out when the display is disconnected and reconnected.

Glad to hear it works...hopefully that means it's less of an issue with HDCP and more to do with EDID. I'd rather not have to buy a switch that is almost as expensive as the console itself when DVI and USB audio (in my opinion) should work out of the box. Hopefully the OUYA devs get around to adding support, but I have more hope for the XDA chefs.

Hi.

I am running a HDMI Audio Switch (Ligawo HDMI Audio Switch ~35€) using a hdmi-cable between ouya and switch and a hdmi-dvi cable to connect the switch with my computer monitor. The switch comes with a cinch-output that is connected with my 2.0 Amplifier.

Funnily enough the switch also solves the resolution problem, I still have when connecting the ouya with my monitor via hdmi-dvi cable. Now my monitor runs brilliant on 720p.

I just bought such a Ligawo device, and whenever I plug in the HDMI-DVI cable, the OUYA seems to turn off sound via HDMI, seemingly because al that digital stuff is so "clever" it knows that DVI doesn't do sound. At least that's what I think, and one of the customer reviews on the device on Amazon (the link I cannot -yet- post here, grmbl) confirms it, kind of.

You don't have that problem?
