Playing sound over HDMI on a Samsung TV

When I tried to connect my HP laptop to a Samsung TV via HDMI, I expected sound to work out of the box, but unfortunately this is not the case. After making sure that my laptop output sound to the ‘HDMI adapter’ and that it was not disabled per the HP support forum, I came to the sudden realization that Samsung treat the input port differently on how you tell it. I registered the HDMI input port as ‘DVI PC’ and usually I use a separate 3.5mm audio cable, so I tried to fiddle with the option (via the input menu -> context menu button -> edit device)

Because DVI cannot convey sound, I had to select ‘PC’, which is a little weird since ‘PC’ is also the term Samsung applies to VGA input, but well, if there were a separate ‘HDMI PC’ category it would have been clearer

Debugging the Galaxy Tab 10.1

When I first plug the tab in, my computer automatically install all the drivers, but it won’t show up in ADB and Eclipse. I did a little searching but people were pointing me to Samsung’s developer page with a USB driver for phones. Sadly that driver just isn’t for the tab, a search on their site found nothing interesting either. It looks like Samsung can’t keep information for developers updated while they are still battling legal issues around the tab.

Fortunately, I remembered I haven’t turned debugging mode on the tab on, so I went ahead and do it, this time… Success!

Now I’m installing Android 3.1 platform and looking forward for a happy time debugging 🙂
