Thanks for the news and the effort on our part, Jamez! I ordered, and received today, the Nvidia/BizTalk DisplayPort<-->HDMI dongle.
I am pleased to report that when connected to my Samsung HDTV via HDMI, the TV shows up as an audio device in the sound applet in Windows 7 Control Panel. Selecting it does send sound to the TV. I don't know why the similar dongle I bought from Monoprice doesn't properly get detected as supporting audio, but perhaps it is because that dongle isn't marked as supporting DisplayPort ++ (dual mode).
Disclaimer: I am running the latest Nvida "Verde" Quadro NVS 3100M notebook reference driver, version 266.58 from the Nvidia website, not the older, official Lenovo ThinkPad-tweaked version (257.38) of the driver. Your experience may vary with the older driver.

Based on engineering's feedback, Nvidia notes that the driver 188.8.131.5238 corrects a prior bug that affected the accuracy of identifying different interface dongles - DP to VGA, DP to HDMI, etc. It detects the dongle as a DP->DVI dongle rather than DP->HDMI dongle. Following additional testing based on our inquiries, Nvidia confirms the new driver is working as designed and will correctly identify adapters. I realize that some members of the forum have adapters that will not provide sound when used with the updated drivers and actually benefited by the functionality quirk of the older drivers.
A tip has been released by Lenovo engineering that summarizes the situation: -> Tip
This is the Lenovo recommended dongle
This is the Nvidia recommended dongle
If you would prefer not to purchase this dongle in favor of another dongle you were already using with the older driver, you can revert to the prior drivers - this is covered in the community KB article here: DP->HDMI Article
Please note that by reverting to previous driver, your Windows Aero might not work properly with 4GB of RAM as this was one of the issues that was addressed by the new driver.

The 184.108.40.20638 driver is for XP...its counter part 220.127.116.1138 for Windows 7 64-bit is what I use. These drivers are the same ones people are using since late 2010.
I can see HDMI but cannot choose it in SmartAudio. The issue is still unsolved.
Also, how about providing DVI-to-HDMI cable that works...that is what I would prefer over a HDMI cable PLUS a dongle converter.

For all with audio issues over HDMI on Win7 64bit, please try this:
The issue seems to be in driver versions v8.17.... of the NVS 3100M.
1. In Device Manager, uninstall your current NVS3100M driver and, when asked, delete all files associated with it. Laptop will revert back to generic VGA driver. You can adjust to 1280 res after reboot to make things a little more comfortable to read.
2. Install v18.104.22.16855 driver for the NVS3100M:
3. Reboot for good measure... connect DP to HDMI to TV, you should get pic immediately. If not, use Fn+F7 to duplicate display. Then Fn+F6 to bring the audio applet, click more audio options double click on HDMI icon,you should have a green checkbox. Open audio mixer and verify audio coming from HDMI device. Also, in audio playback devices you should see the HD Audio device as connected.
I am not sure how a company like Lenovo can go on like this. Simple integration testing discovers these issues.
Hope this helps.
