Re: [pulseaudio-discuss] Pulse audio does not work with my hdmi output
Ok I found out more, it can work but I have to do a step first. My testing before was pulseaudio then alsa but I never went back to notice that pulse started working. It seems on my hdmi output that after ever boot I have to use 1,9 first then it initializes 1,3 1,7 1,8 and they work fine after that. So all I need to know is how can I force Pulse Audio to use plughw:1,9 always instead of the first detected 1,3?

Does the VU meter in pavucontrol indicate sound is playing? Can you supply pacmd ls when something is playing (e.g. a stream should be audible, but it's not)? Also: amixer -c [card name/number here] would be useful too. If you want to be super helpful, then the output from pulseaudio -k; pulseaudio -vvv would be nice too (although you may need to copy /etc/pulse/client.conf copied to ~/.pulse/client.conf and disable autospawn to get past the pid file error this produces when PA is already running.
