[Alex Mayorga]

Steps to reproduce:
1. Play audio in one session (pause audio)
2. Switch to another session (via shutdown menu)
3. Mute audio on the second session
4. Close the second session or switch back to the first one

Expected results:
Audio on the initial session remains at the initial volume level.

Actual results:
The audio is muted on the initial session too.

Hi Alex,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

Are the users the same account or different accounts?

[Alex Mayorga (alex-mayorga)]

Different accounts.

[Alex Mayorga (alex-mayorga)]

Tried with the kernel below from http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/current/ same problem.

$ uname -a
Linux VPCCW1FFXL 2.6.34-999-generic #201003271003 SMP Sat Mar 27 10:10:21 UTC 2010 x86_64 GNU/Linux

Also figured this workaround to regain sound on the incorrectly muted session:
- Click the audio icon on the notification area
- Click "Mute All"
- Click the audio icon on the notification area
- Click "Unmute"

I'm pretty sure this isn't a bug in the driver, and I'm pretty sure it
isn't a bug in pulse - the latter notes that it's by design, since the
active consolekit seat has control of the mixer device.

Are you _certain_ that your users aren't in the audio group?

[Alex Mayorga (alex-mayorga)]

User on the initial session that gets incorrectly muted:
alex-mayorga@VPCCW1FFXL:~$ groups alex-mayorga
alex-mayorga : alex-mayorga adm dialout cdrom plugdev lpadmin admin sambashare

User that I switch to and mutes the initial session:
alex-mayorga@VPCCW1FFXL:~$ groups nelisalr
nelisalr : nelisalr adm dialout fax cdrom floppy tape audio dip video plugdev fuse lpadmin netdev

[David Henningsson (diwic)]

Please make sure that user nelisalr is not member of the "audio" group and then try again.

[Alex Mayorga (alex-mayorga)]

Removed the user from the "audio" group.

alex-mayorga@VPCCW1FFXL:~$ groups alex-mayorga
alex-mayorga : alex-mayorga adm dialout cdrom plugdev lpadmin admin sambashare
alex-mayorga@VPCCW1FFXL:~$ groups nelisalr
nelisalr : nelisalr adm dialout fax cdrom floppy tape dip video plugdev fuse lpadmin netdev

Still when switching to the second user whose audio is muted, logging off and logging back as the first users mutes the first users audio.

There is no support on such deprecated version; that one has died long time ago.
