I have an nvidia gt220 card in a lucid machine running 0.25 fixes via mythtv repos.<br><br>I can't get hdmi audio to work.<br><br>The following data points seem relevant:<br><br>kernel 2.6.32-44-generic<br>cat /proc/asound/version - 1.0.21 (suspect a problem here)<br>
ls /proc/asound shows an ICH card and an NVidia card.<br>ls /proc/asound/NVidia <br><br> codec#0 codec#1 codec#2 codec#3 id oss_mixer (NOTE: no pcm devices)<br><br>myth scan shows only ICH devices (as well as the usual null and /dev/dsp stuff)<br>
<br>nvidia drivers are 195.36.24<br><br>There are no /etc/asound.conf or ~/.asoundrc files<br><br>This machine is an older P4 SFF machine that was last used pre the 22/2/2011 earthquake, when it was connected to an external usb sound device to a spdif 5.1 sound system. Times have changed, and now I want it to simply connect it to a TV via hdmi for a kids room (no surround sound system). I have updated all the packages after moving mythbuntu-repos to 0.25-fxes, so it is right up to date.<br>
<br>I am thinking the solutions might be any of:<br><br>*get a newer nvidia driver from some ppa or other (if so which one)<br><br>*get a newer alsa version via some ppa or other (if so which one) <br><br>*ditch the current os and install 12.04 (which is probably future proofing as I will want to move to 0.26 and beyond soon anyway, but I'll only do it now if it will fix this right now).<br>
<br>However before I start futzing with an otherwise good system (the graphics form the gt220 are good aren't they!) I'd like to know if anyone has a solution, rather than me experimenting all weekend.<br><br><br>
