AMD Intentionally Added Artificial Limitations To Their HDMI Adapters 256

An anonymous reader writes "NVIDIA was caught removing features from their Linux driver and days later Linux developers have caught and confirmed AMD imposing artificial limitations on their graphics cards in the DVI-to-HDMI adapters that their driver will support. Over years AMD has quietly been adding an extra EEPROM chip to their DVI-to-HDMI adapters that are bundled with Radeon HD graphics cards. Only when these identified adapters are detected via checks in their Windows and Linux Catalyst driver is HDMI audio enabled. If using a third-party DVI-to-HDMI adapter, HDMI audio support is disabled by the Catalyst driver. Open-source Linux developers have found this to be a self-imposed limitation and that the open-source AMD Linux driver will work fine with any DVI-to-HDMI adapter."

          HDCP doesn't rely on cable behavior (aside from good-enough-for-signal-integrity performance) between sources and sinks to enforce DRM. So, for a mere physical pinout adapter, there should be nothing that a 'malicious' cable could do (unless that 'cable' were a full-fledged HDMI sink baked into a line lump, which would be physically possible but wouldn't really be a 'cable' anymore), nor would there be anything (save blocking the audio entirely) that a 'trusted' cable could do to control a malicious HDMI si

          It shouldn't, since it's ridiculously easy to work around.

          Don't install the Realtek drivers.

          Remember, Microsoft provides the Stereo Mix utility of the audio subsystem, and in order to pass WHQL certification, the drivers have to meet the minimum spec defined by Microsoft. So Realtek may have agreements with whoever-it-is (and it's not Microsoft) to remove the Stereo Mix from their drivers, but the WHQL certification process requires that it be enabled.

          So don't install the drivers that have Stereo Mix disabled, and let Windows Update install the WHQL certified ones instead. I have Realtek audio in my system, and the Stereo Mix path works fine. It can take a bit of work to find how to activate it in Windows 7, but it's there, and it works.

      Because DVI isn't supposed to carry audio.

      I suspect there's a licensing agreement somewhere saying they must conform to the DVI spec, including its lack of audio support, but if they count the HDMI adapter as a part of the whole system, they're just using a DVI-like connector in the middle of an HDMI system.

      Another cause could be avoiding liability. If they send out audio by default and it breaks some other device, they're at fault. If the other device asked for it (by the presence of the special chip), it should be able to handle it just fine.

      As yet another possible reason, the audio-over-DVI system could have been designed as a feature, that AMD simply abandoned. Since they've done the work implementing it in their chips and adapters, it costs almost nothing more for them to keep using it, probably even costing less than it would to support separate product lines with and without the capability. However, they may not want to run the extra expense of publishing and supporting yet another standard, when HDMI is already showing wide adoption as the next standard for everything.

        This is exactly what's happening. Reading the summary, my first thought was that it was incorrect and my second thought was that the writer was clueless. After all, DVI doesn't support audio so how can DVI out provide audio to a DVI - HDMI adapter? The answer is; only by breaking the standard.

        So, if you break the DVI standard and send audio out what happens? There are no adverse effects, at all, ever, even when the connection is DVI - DVI? It seems to me that they are simply adding a safety feature to their non-standard implementation. 'If we don;t know for absolute certain that the end point is HDMI, don't send audio out the DVI interface.'

        So that they can choose when their hardware becomes obsolete.

        One of the biggest unspoken threats of Linux is the added longevity hardware picks up. People can use much older hardware because Linux has a much more broad range of support for hardware than any one version of Windows. Why is that? You could argue that supporting device X under all versions of Windows is expensive or some crap like that. But at the end of the day, Linux does this because it's just there... in the kernel source somewhere. But when hardware makers want to push new high-end devices, they sometimes encourage upgrades by disabling features, decreasing performance and all manner of dirty tricks.

        If people were wondering why AMD and NVidia have been holding back so hard on their Linux support, I think this is a much more plausible reason than "we outsourced development of the drivers and they patented and/or copyrighted stuff."

      My guess is because the DVI standard doesn't actually have an audio transport channel, so they only switch it on when a DVI connection that they recognize as a DVI-to-HDMI adaptor is attached. They can only do that when one of their adapters is attached. Otherwise, they see a DVI device so they output a proper DVI signal. It's sticking to the DVI specifications very precisely (perhaps a bit too precisely).

On most Blu-Ray discs it happens at least twice before you get to playing the movie. With DVDs it sometimes takes place 4 times. I swear that an old CRT TV and a VCR were faster to cold-boot to a visible, playing movie, with inclusion of loading the tape, than the current generation of HD gear. It says something when a system that could, theoretically, be up and playing in 5 seconds from power-up is almost a factor of magnitude away from what the hardware allows it to do. It really takes the cake when such a system is about as "fast" as an electromechanical variant. Yeah, VCRs are nowhere near the quality of even DVDs, but still.

    Terribly sorry for not RTFA, but when did AMD try to add this to the Linux driver? When was it noticed? When was it corrected? And can I shove this in the face of windows fanboys who say that anyone could submit anything they want to Linux and you don't really know what's in there?

  • I wasn't aware that DVI could carry audio. Of course, most of my available DVI output display doesn't have audio. And if I have audio-out with DVI, I probably also have HDMI. So basically the only time that this is a problem would be if I had a DVI only display with audio and I needed audio.

      It can't. The complaint is that a non-standard feature is only enabled for known non-standard adapters. The story is flamebait.

    • solution is to NOT bundle a+v together. its a stupid idea, the way its done now, anyway.

      carry your audio over spdif (opto or coax). its standard that way! you can run into YOUR dac of choice for audio and also into your spdif opto port on your typical avr receiver.

      you won't get blueray 2496 audio - it will be 48k audio at 16bits (maybe 24; spdif has no problem with 24bit audio even at 48k sampling) but for movies WHO THE HELL CARES. redbook is and always has been good enough for movie use. and dd5.1 an

    • The adapter in question allows you to plug a HDMI cable into the DVI connector on the video card. My 4850 card from ASUS had two DVI connectors and no HDMI connector, so I would have to use the adapter to plug it into a TV for example. The card came with one. My later 6850 card has HDMI and DisplayPort and didn't come with one.

      Since the 4850 card has two DVI ports, I wonder if the idea was something as simple and stupid as if there are two DVI to HDMI adapters plugged in, only activate HDMI audio on one, a

    While I didn't try sound over my third-party DVI-HDMI cable, I did have issues with the open source Radeon driver and these cables. Once Linux booted, the monitor would keep dropping the video signal and then re-establishing it. At first I thought X was in a crash loop, but the keyboard and mouse seemed to remain responsive. Rather than mess around with it, I just used a VGA cable, but that definitely left a sour taste in my mouth and had me longing for the days when cables just shoved whatever data was pushed to them.

    I guess I'm missing something here. What is the big deal if HDMI audio is turned off when using DVI since DVI doesn't carry an audio signal anyway?

  • Haven't they realized by now that one tiny little reason to make a customer buy their competitor's products will cause them to do so? Here it is. Mandatory, proprietary, overpriced crap is why Dell fell off a cliff in the business world. Why buy that $3 replacement fan when you can get a $40 one from dell because one one little plastic tab? Customers gave them a big, fat "fuck it, we're buying Lenovo" and jumped off that train like it was on fire. Good luck with that one, AMD.

    Do people really think this is to screw with their customers? AMD makes pretty much zero off their adapters. They clearly aren't doing this to protect revenue streams. It's obviously some workaround hack for something, or some end case that wasn't initially considered in the design, or conforming to the dvi spec somehow. I'm really not sure why people think this is malicious. Really? THIS is what's going to make you not buy AMD?

    If AMD put HDMI ports on their video card, they'd have to pay licensing/royalty fees to HDMI Licensing, LLC. By only putting DVI connectors on their video cards, ATI doesn't have to pay the fee. But for the small percentage of customers who *want* HDMI, they sell the adapter and pay for the licensing costs with that instead. Since they sell far fewer adapters than cards obviously, the overall license fees paid become much less.

    Presumably the EEPROM is in there because the HDMI Licensing lawyers aren't complete idiots, and required the card to make sure the adapter is licensed. Tossing a 10-cent 24LC01 or something in there with a magic byte on it probably didn't break the bank.
