Applications segfaults when accessing audio

[John Lik]

Most applications with some kind audio component segfault when started as a normal user, works ok when launched with sudo.

Sound does works.

Example :

$ alsamixer
Segmentation fault
$ dmesg | tail -1
[85176.329383] alsamixer[1311]: segfault at 9f9eebd8 ip 9feedaf7 sp bfc5dfb4 error 4 in libpthread-2.8.90.so[9fee7000+15000]

But
$ sudo alsamixer

Works ok

Same with the volume control applet

User is in the audio group :
$ id
uid=1000(demo) gid=1000(demo) groups=1000(demo),4(adm),20(dialout),24(cdrom),25(floppy),29(audio),30(dip),44(video),46(plugdev),107(fuse),109(lpadmin),115(admin)

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.
If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
