Re: Pulseaudio - mutliuser issues.

Okay, After multiple tests, adding users to the audio group is a disaster. Lose much of the idea of using Linux.

Last night did my updates and did a reboot for the kernel and did a quick audio test and everything seemed to work okay with people in the audio group and I did test just playing a video on at least three different users and they worked.

This morning I needed to do a web conference and plugged in the camera and couldn't get it to work or the mic on the camera or an external mic. All have worked in the past.

After this, the audio was screwed up in other accounts. I didn't log any of them out since my test last night.

The only way to get things working correctly is to remove all users from the audio group.

Will have to play with the camera and mic later to see if that is working again.

    I did make one change to groups and I have reverted it just now.  I
    added the user that takes control of the sound card to the audio group
    as I was trying to get ZynAddSubFX to work and that was one of the
    suggestions.



I believe that this might be actually the reason. Add the other users to the audio group, too,
and let's see what happens. I believe it could solve the problem.
