Mini Mac late 2009 to HDMI TV audio issue

[ramin8296a]

I am using my mac mini (late 2009) which doesnt transfer audio over mini display port. so i connect the mac to tv via a hdmi cable and I'm using a mini display to hdmi converter. and for audio i am using an av cable directly from mac to the tv.
My TV (LG 32LB550B LCD HDTV) doesn't recognise the audio and video together. It seems to be 2 different inputs as far as the menu goes (i can switch to "hdmi" and see the video and i can switch to "AV2" and hear the audio.
is there anyway that i could have both audio and video together on tv?

To my knowledge, using a mini display port to HDMI converter should transfer sound as well (since HDMI is a digital signal and carriers sound and video), at least it does for my MacBook Pro. You shouldn't need to run an AV cable. Have you tried it without the AV?

You are right that there is no audio input associated with an HDMI input since that is audio and video. You need one of these:
