RE: Sound not working
I think there is a error in your advice. The correct command you want
is
groups username
Without the user name, at least on my distribution, the groups command
gives the
groups for the current process.

> I have a pc where I have two sound cards. I have a software application which receives audio signals from network and plays it using alsa. However, I have two sound cards in the system and I need to have the same audio from the other sound card as well. I tried to do this in alsa but couldn't manage it. Therefore, I ended up here in pulseaudio. However, I have no idea where to start and how to implement it. Is it just a matter of configuration file? My purpose is to copy the audio which is being played in the other sound card.

When you take it to the Ford dealer, they say "Sorry, the problem is with the quality of steel used in the engine design.? This problem is below Ford.? We don't make steel.? Go talk to the steel manufacturer."? This is exactly what you told me to do.
