HDMI

 I installed Ubuntu Local Language Remix on my dynabook N40, but there was a problem with unstable bluetooth, so very difficult to use it .

The other day I started using a Toshiba REGZA as an external monitor, and while I was doing so, I found that HDMI sound was recognized by Ubuntu when I opened the sound menu from the settings menu. I selected this option and the REGZA began to play sound (!!). This solved the problem, but for some reason, this setting reverted back to the original every time I rebooted the dynabook N40, so booting up and setting the sound became a routine task every time. This is tolerable, but I will give up bluetooth for the time being, because I don't have to worry for a while as long as I can hear sound, although the bluetooth instability problem of Ubuntu has not been solved (:-o).
