1. Kanex Usb Zu Hdmi Adapter Mit Audio (for Mac) 91 15 Chf Symptoms

Hi, I just purchased a Kanex Mini DisplayPort+USB Audio to HDMI Adapter for my new Samsung flat screen so I could watch netflix movies. The guy at Tekserve (NYC based authorized dealer) said it's really cool b/c it's audio and video all in one. Two cables are attached to a small box on one side and on the other side of the box is for the HDMI cable which goes to the TV (most of you prpbably already know this) 🙂. The two attached cables fit into the the USB (audio) + mini display port.

The video works great, but no sound. I called Apple for tech support and we tried a few things like changing the sound output to USB, but no luck. I can call Tekserve on Monday, but would love to figure this out before then for the week-end.

Thanks everyone for your help. There are actually 2 different Mini Display port to HDMI adapters from Kanex. One supports 2 channel audio through the USB audio out cable, which is the one you have Mary. The other one with the extra audio plug cable supports 5.1 digital audio.

I don't have either of these adapters but I would think that you 'should' be able to go into your System Preferences under Sound. If the USB plug from the adapter is plugged into your MacBook, then it should show up in the output window in the Sound preferences which you would then choose instead of outputting the sound to the built-in MacBook speakers.

At the bottom of the product description page of the adapter that you have (the USB 2.0 version), it says this: +Sound Output setting on Macs must be changed to 'USB Sound Device/USB Type' to have the adapter operating correctly.+. Let us know if you get it working properly. I'm considering getting one also. I just re-read your initial post and it sounds like you already DID try switching the sound output to USB with no luck. The only other thing I can think of is the adapter might be bad and maybe exchange it for another one from where you purchased it.

Or you could maybe exchange it for the 5.1 digital audio out version. Although it sounds like your sound is going directly into the tv via HDMI and not a surround sound receiver. Kanex does have tech support and contact links on their web page.

Maybe you should email them directly about your problem. Unfortunately I'm sure you'll have to wait til sometime during the work week to get a reply back.

From displayport.org/faq: Q. Does DisplayPort also support audio? Yes, DisplayPort supports multi-channel audio and many advanced audio features. DisplayPort to HDMI adapters also include the ability to support HDMI audio.

I wound up on this page however because my DisplayPort audio wasn't working. After searching many sites, I learned that the video driver (vs. Audio driver) is responsible for the DisplayPort audio; while updating my video drivers (Intel HD Graphics 4600) I specifically noticed in the log it installed an Intel audio driver as well. After this driver update I'm able to see the TV/audio device listed under Control Panel-Sound (LG TV/Intel Display Audio), as well as under Device Manager as Intel Display Audio (in addition to my regular audio device).

As others have mentioned, it's up to the manufacturer to support/implement audio over DisplayPort. Other research has indicated that the DisplayPort to HDMI adapter must also support audio. Odds are if you're using a laptop with a common video device like Intel or AMD, they implemented audio over the DisplayPort and you just need the drivers for it. Bottom Line: Update Video Drivers.

Thunderbolt is a combination of DisplayPort and PCIe and is the same formfactor as MiniDisplayPort.

When using a DisplayPort cable (MiniDisplayPort receptacle on one end, fullsize on the other, I can only do video, System Preferences Sound does not give me the option to output sound to my TV/Monitor (this is the same monitor that I can output sound to when using a HDMI adapter, a Dell 3008WFP). From my testing it may technically be possible to do audio over the DisplayPort protocol, ports and cables, but on a MacBook Air 13 inch, Mid 2011 model it is not possible with DisplayPort - it is possible with HDMI (presumably it is using PCIe-to-HDMI and not translating DisplayPort-to-HDMI).
