View Full Version : mythbuntu hdmi to tv overscans and no audio

July 1st, 2010, 12:42 AM
i just installed mythbuntu 10.04 on my acer aspire m1100, but the output to my tv (th42px80u) through my geforce 8500 gt (hdmi) and it's overscaning the screen. the audio through hdmi isn't working either. i had i working on vista right before i installed mythbuntu (ironic isn't it?). i installed nvtv, but when i click on it to start, noting happens. i searched the internet for several hours without success. i updated the nvidia driver, but still nothing.

Did you unmute HDMI in alsamixer?
Did you set the audio to HDMI in Mythtv setup?

i got the overscan worked out (i installed the other driver shown and the overscan option in nvidia panel worked). i went to asla mixer and made everything visible and unmuted them all, and unfortunately it's not working. i looked through myth tv front end and back end settings and i couldn't find the relevant setting, am i in the right place?

i changed the output device to hdmi and spdif (i remember that was the name of the internal connection i used), but neither of them worked. i do have an old crappy speaker that i plugged into the headphones, so that is working. what's aplay? im a noob.
