Pulseaudio preventing dual audio outputs
Summary
I am attempting to output audio through the two monitors I am using on ubuntu 20.04. Ubuntu settings shows both monitors as options in the settings, and I installed saprefs whickh will only recognize a tv and the headphone jack. with the help of a reddit user we found that the two outputs are part of different profiles. ultimately i was able to get both outputs to play an audio file at the same time by following the directions attached here: ` pasuspender sleep 600
now open two other terminal windows
and in both of them, navigate to where the asd.wav file is (it should be where the original file was)
then run
aplay -D "hdmi:CARD=NVidia,DEV=0" asd.wav
and confirm that you can hear it on the TV, then don't stop it, go to the other terminal, and run
aplay -D "hdmi:CARD=NVidia,DEV=1" asd.wav
and check if you can hear the audio from both TVs
then stop the "aplay"s by pressing Ctrl+C in their terminals first, then do the same with "pasuspender"`
environment
Please see attached pa-info.txt
Steps to reproduce
As far as I know this bug is default. this is a fresh installation and prior to the aforementioned help I have only installed paprefs
What is the current bug behavior?
I cannot play audio through two attached devices simultaneously.
What is the expected correct behavior?
being able to play audio through both devices simultaneously.
